When I started my car, I went to turn the AC on and there was beeping and the emergency brake, ABS/stability, and a few other instrument panel lights come on. The overhead interior light comes on as well and the air will not blow out. The only way to get this to stop is to turn the A/C off or either turn it up to the highest level (5). If it is on 5 and I try to turn it down, the beeping starts and the lights come on. Sometimes it will just happen randomly even if I don't touch the air. Once while I was on the interstate doing 75 MPH, it randomly happened and my car stalled and slowed down as if it were cutting off which scared me so badly because if my car had cut off I could have been in a serious accident, or even with it slowing down the way it did. My foot was on the gas driving and the car just started slowing out of nowhere. Also, the air bag light has come on and will not go off and the air bag has never been deployed. I love my truck so much, but am considering getting rid of it if I cannot get any assistance with getting it fixed because of my concern for my family's safety as well as other drivers on the road.
2007 Chevrolet Trailblazer electrical complaints
Page 6 of 8: complaints 131 to 160 of 200, newest first, as owners wrote them.
Driver noticed smoke and burning electrical/plastic smell coming from the driver door in the area of the door and window buttons. Stopped at a service station and had the mechanic look at it. He pulled out the driver control module and said it had started to burn. The top and side of the unit was melted. This rendered all of the buttons inoperable. The door control unit was left out of the door to minimize further risk. *tr updated 9/13/12
The fuel gauge level indicator just went from "full" to "empty", it just went that fast. Minutes before it had just been filled at the gas station. When starting, the gauge rises then falls to empty. On occasions the warning message, "please tighten gas cap" comes on. Now months later, same problem; after contacting "gm" hotline, they still have not shown any concern. I keep track of miles driven since last fill-up and gas used, so I know when it is time to fill-up. I have read many same complaints, and I wonder why "gm" has not issued a recall. It is now 08/21/2012 and problem is still ongoing. Can you please help. Please. "gm" has on numerous occasions suggested that the wire harness on top of the gas tank needs to be replaced, to do so, requires a five (5) hour visit and they expect the customer to pay half the cost. Please help.
During a heavy rain, opened door and inside of door panel was soaked after it was done raining I dried off door panel and window would not work I was told that a module may have gotten wet. *tr updated 09/05/12*lj pictures received 09/05/12
Intermittently the power locks, windows and auxiliary power would work and not work. After a few weeks of the 'work, not work' it just plain failed to work. *tr updated 09/07/12*lj repair orders received. Updated 09/11/12
Vehicle was parked with all doors locked and the vehicle not running. The remote unlock button was engaged and all doors unlocked with the exception of the driver door. The remote unlock was engaged 3 to 4 more times. The door was manually unlocked from passenger's side. When the door was opened, smoke was pouring out of the inside. We poured available liquids down the window slot but smoke was still pouring out. While my spouse went inside the business where we were parked to grab a pitcher of water, I jerked the plastic oval piece around the inside door handle off and saw flames. He returned with the pitcher and we poured the water down the open hole at the door handle and finally managed to extinguish the flames. We drove the vehicle home but none of the door functions worked at all. It is going to cost me approximately $600 to fix this issue. I have been afraid to drive my trailblazer since that time. Also the fuel gauge quit working about 3 months ago. We finally fixed that issue today. The next issue to repair after the door is the heat/air actuator as the air conditioning no longer comes thru my air conditioning vents. *tr..

We were on vacation and we were getting ready to leave and we tried to unlock doors to enter vehicle and all doors except the driver door unlocked. A passenger leaned over to unlock the driver door and hit the driver window down switch. The key was not in the ignition. A burning smell was noticed and the driver door was completely dead. We were able to open the door and drive the vehicle. When I returned home I popped out the driver door module and noticed that the plastic case was melted. I opened the unit and noticed that a wiring harness connecting the 2 printed circuit boards was completely burned. Luckily this did not cause a major fire. *tr updated 12/27/12 *cn updated 12/31/2012
Driver's side door switch panel had an electrical fire (smoke only, no visible flames) while in motion. Driver side window operated without driver's touch, smoke from electrical fire inside of door came thru seams of the interior finish panels. Fire did not spread however no controls on the panel work anymore.
On vacation with my family last summer the windows upon entering the vehicle started to go up and down all by themselves. It almost caught my sons arm inside of it. After a few minutes the windows stopped and remained down. We couldn't get them to go back up for a few hours and had to leave them down overnight. The next morning my husband went out, turned the key, pushed the buttons and they all went back up. He told us not to touch the windows just in case weren't able to get them back up. Once we returned from vacation I took it to a suggested mechanic as per my warranty company. They diagnosed it as the master window switch, the gentlemen told me that they are about 2-3 hundred dollars and are not covered under warranty, imagine that!well I paid the gentlemen for his time and have been without windows for over a year now because I make my 500 payment every month and do not have the extra money not only for the part but then for labor and to have it programmed by an authorized dealer. Now I see that this is a common problem with this year trailblazer, are we waiting for someone to die before we issue a recall? I sent an email to gm about it and they did contact me, what they said is to once again have it diagnosed at an authorized gm dealer (ok more $) then they would look at the report and if they ok it I would then be reimbursed for everything (ok good one) I just had it diagnosed and still have the report but I need to get another one, come on people I don't make your salary and have 2 kids to support! . So I took it, well when I talked to the gm dealer they said just to look at it will be about 100 so I cancelled the appointment. That is very sad that gm would knowingly let this go on with out offering to fix the problem. I will never buy another gm motors vehicle in my life, sad to say that I will be buying not made in the USA vehicles from here on out. *tr updated 8/22/12
The power window, side view mirrors power seat and power door locks stopped working. Took it to a private mechanic and the wires have melted. The module cost me $385.00 plus another $110.00 to program the module. I also have a problem with the gas gauge, it tells me that I have low fuel but even when I fill the car up, it still tells me that I have low fuel.
Vehicle was parked for the evening, turned off, no key in ignition, and unattended. Driver door module worked fine the previous day. The next morning, no parts of the module worked. Upon investigation, we discovered that the left side of the module by the driver window button had a burn spot on it and smelled like an electrical fire. The dealer quoted the part only price as over $300.00. *tr updated 7/31/12 *cn the dealer replaced the door lock module. Updated 08/01/12

I noticed months ago that the lights weren't working on the power windows switches on the driver's side of the truck. I have definitely noticed some odd smells (burning/melting/plastic/chemical) that I was never sure where they were coming from. Before the issues with the lights, which was probably around the beginning of november, the one touch window opening control button (all the way down with only one touch instead of holding the window button) stopped functioning, the window would stall in the middle of either closing it or opening it and when it didn?t stall and closing/opening was successful it would be very, very, very, very, very slow. The window in my truck is now dead. It will not operate at all. I went to try to shut it monday night and it wouldn?t shut, there is about 2-3 inches of space where the window is down. There is no power to any of my window controls, or to my power locks on the driver?s side. While doing some research on this issue I came upon this site where others had listed very similar problems. I also understand that this is currently under investigation to see if a recall is warranted. Given that this is a very well known problem, what recourse is there for the unsuspecting consumer? I purchased this vehicle less than 1 year ago as a used vehicle.
I had a drivers master power switch that melted too, it happened on march 04 2012. We got in the car and could smell something, we drove with the windows opened for about 1 hour. On march 5, we went out again but had to pull into a auto repair shop, the smell was still there. They pulled the master switch on the drivers door and the switchs had all melted together. He disconnected everything. We contacted chevrolet and they are in the process of replacing all the switchs. I'm worring about the smell and if it will go away. This must have happened during the night before we got in the car.
I noticed that when I roll the windows up or down the lights flicker. Now I am hearing the sound like the doors are locking or unlocking by themselves and I am not touching anything. This happens when I am going 60 as well as when I am going slower speeds.
2007 trailblazer ss drivers door module/window switch on my normal commute to work, I had noticed a faint burning smell of plastic that would only linger in the cabin for a few seconds. The smell continued for almost a week with the same symptoms and then disappeared for almost 4 days. After the smell of burning plastic was no longer there, one night while driving, the drivers door module lights (drivers, passenger, rear windows, window locks, and lock) were flickering and noticeably power surging. I was concerned about this issue so I had done some research online looking for any information that may lead to a solution to my problem and if any other trailblazer owners were experiencing the same problem. Seemed to be a pretty popular problem among trailblazer owners ranging from 2004 and up. Some research indicated that wires may had been broken inside the insulation that goes from the interior of the car to the door. I had the vehicle inspected at a chevy dealership and they told me that the ddm was functional and just needed a fuse replacement. That same night when moving the vehicle from the street to my driveway, smoke started pouring from the top of the door panel and it was obvious that plastic was burning and on fire. I then pried the drivers door module off and noticed a dime sized hole right under where the drivers window switch button is located. That hole still singing I disconnected the ddm and have been driving with non-operational windows ever since.
I was driving home from work and started smelling burned wires - then smoke started pouring out of all creases in my driver side door. I pulled over and had a drink with me and dumped the whole thing into the door to get it to stop. Fire dept came and told me not to drive the vehicle and had it towed to the dealership. The dealership determined in was a faulty driver door window regulator and it had a hole burned through it. I looked on internet and saw this ad: http://autos.winnipegfreepress.com/news-article/id-4400/ this is exactly what happened to my car. Insurance says not covering it. I could have been injured very badly as I was on the highway and there was so much smoke in my car.
Tl* the contact owns a 2007 chevrolet trailblazer. The contact stated that the wires in the door panel melted. The contact took the vehicle to a local mechanic and the mechanic could not diagnose the failure. The contact did not take the vehicle to a dealer. The failure mileage was 64,000.
The fuel gauge on my 2007 chevy trailblazer began fluctuating from proper fuel level reading to empty at around 74,000 miles. After few weeks of this, the fuel gauge now consistently reads empty after driving 115 - 120 miles on a full tank, which indicates a failure of the fuel sensing unit. I am driving the vehicle based on the trip odometer and I have run out of gas twice since this is not a reliable way to estimate the amount of fuel in the tank. Both times I was on my way to work a on heavily traveled bridge with no shoulder. This is a huge safety hazard!!! Also at around 75,000 miles the driver side door lock stopped working and the electronic stability control off light and electronic stability control maintenance light periodically turn on.
Fuel sensor never gives correct reading causing me to run out of gas on 2 separate occasions, also the drivers side door control panel keeps going on and off only working some of the time and going in and out as I am driving.
My fuel gauge no longer works. I also have no power anything on my drivers side door.
Fuel gauge drops to empty with low fuel light coming on, no matter how much gas is in vehicle. Sometimes it fluctuates back and forth. Never sure how much gas is in vehicle. Which this creates a big problem since I transport handicap people in my vehicle. Also driver side window operates very slow, sometimes it hesitates on rolling up. I have to let it set for a while, then try rolling it up again. After several times doing this, it has finally rolled up all the way. I think the dealer should fix these problems, without consumer paying for any of it. Especially since these seem to be ongoing problems. I have been lucky reference my door panel hasn't caught fire yet, which could cause a serious traffic accident. Also my slick, skid control lights come on very easily when I take off and stay on till I can shut the car off and restart it, and hope doesn't come back on when I start to drive.
My right passenger door panel caught on fire. The car was parked in the drive way and was not running. When will this be recalled? Does some one have to die before this is fixed. This is a known on going issue. Its sad when you look out your door and see your car smoking while it is not running.
Tl* the contact owns a 2007 chevrolet trailblazer. The contact stated that the driver's side window was open and there was an odor of smoke. The vehicle was taken to an independent where they advised the contact that the door mechanism was melted. The vehicle was repaired for the door mechanism. The manufacturer was contacted and offered no assistance. The failure mileage was approximately 50,000. Updated 04/10/12*lj updated 04/16/12
Initially the driver's door lock and window controls (for all doors and windows) stopped working. On february 17th, while driving the vehicle, smoke was visibly emitting from the inner door handle. The entire switching system had to be replaced.
I woke up one morning to a smoky garage and noticed my driver door module had caught on fire, luckily the whole truck did not catch on fire in my garage while my family and I were inside our home sleeping. I can no longer control the power windows and locks in my truck. I contacted my local chevy dealer and they tried charging me nearly $1000.00 for a module and door panel replacement and notified me there were no such recalls on my vehicle at this time. This is not the first incident I also had another fire while at a drive through window, the wiring to the cigarette lighters inside my vehicle caught on fire a few weeks after the door again the chevy dealer said there are no recalls and I would have to pay out of pocket. So many what if questions come to mind. This is not the only trailblazer I have known or read upon to have electrical issues or even fire damage. Gm definitely needs to take responsibility before there is harm to anyone due to these unknown fires.
I was having problems with the drivers side door control panel for about 3 days. On 2/22/12 the controls did not work for the drivers side window and the window was stuck in the up position. On 2/23/12 when returning to my vehicle the window was in the complete down position. I started my vehicle in attempt to roll up the window but the controls didn't work. After about 15 seconds I noticed a burning plastic smell coming from the controls. I immediately shut off the vehicle and popped off the control module to find smoke coming out of the opening. I disconnected the wires and removed the module. I could see what appears to be an internal fire in the module due to the melted plastic and housing of the unit. I'm glad that I have some sense of mechanical aptitude because this could have caused a lot of damage.
