2005 Chevrolet Trailblazer electrical problems

Filed Dec 30, 2022 · Electrical, Lights · OK

For several years the low beam headlights would go off and on intermittently. Now, they are mostly off which means I cannot drive my vehicle at night anymore unless I want to blind people or get stopped. I have changed headlamps, relays and fuses to no avail. Now, I see that many others with the same make and model SUV have been having the same issue but no recalls have been issued for this year model. This is a major safety issue when we have to drive with the high beams on and when the lights go off unexpectedly. If you will issue a recall for one year model having a particular issue, why would you not do the same with all year models having the same issue? Come on chevrolet and the federal safety agency, let's get this problem solved to save some lives. It is very scary to be driving and have your headlights go out and a major pain to have to be sure you are home by dark or not be able to go out after dark because your headlamps are or may stop working.

The gauges don't work properly and when the gauges are tapped the trailblazer stalls. The vehicle was in motion on a highway.

I own a 2005 chevrolet trailblazer (bought new) with approximately 79,000 miles. The fuel gauge light is illuminated indicating I am low on fuel however my gas tank is full. I noticed the problem after filling my tank (no light on at the time). After filling the tank, the fuel light came on and the gas gauge bounced back and forth from quarter tank to half tank and now the light stays on with gauge showing empty. I would appreciate any help you can give or recommend any possible action to take.

The speedometer isn't working. I've been hearing how common this issue is. Every now and then it will jump to a random spot when I start the vehicle and stay there. But it never moves while driving

In motion or parked my speed and my tac just stop at random numbers. I have to shut my car off if my speed is stuck. Everytime I do this my speed drops 5 MPH so if I'm stuck at 20 I have to do this 4 times just to get back to 0 MPH I have called chevy . They told me it will cost me over $800 to fix this. Kinda strange the recall doaent effect only the trailblazers don't you think. I have been in the automotive feiod for over 10 years now and I know alot of chevy have had this recall so it's time for you guys act.

Vehicle purchased 2008. It had 35,412 mi. In 2011 the vehicle would have a rough idle and stall in traffic. Sometimes as many as 3 times on a six mile round trip. Always would stall driving around town. I had replaced cam vrr temp sensor fuel throttle. All coils plugs water pump battery motor supports belt windshield washer bottle and motors flush fuel lines. Wheel hubs and bearing rounds crankshaft and power steering pulley power steering pump oil changes 2500 to 3000 miles synthetic oil. All fluids changed and flush rear differential transmission shifter cable. Several diagnostics at chevrolet. Left there they drove it cut off once. Finally, I kept watching gauges oil pressure dropped 44 to zero. Car cut off rectangles it pulled over wait 30 mins. No oil on dip stick. Called firestone took it there. Oil sending unit defective. Changed all oil. They found it. This was a big safety issue over several years for me. Afraid get run over by truck. The vehicle has not cut off one time. I reported to chevrolet. Put in bank there. Please check oil sending unit. Seen numerous trailblazers with this issue. On the web.

I am experiencing all issues identified with recall due to door switch sensor being defective. Intermittent working of door locks not locking or locking and won't unlock . Windows won't work sometimes, and sometimes they will . Lights won't shut off in interior, or won't go on . Delay feature where radio , and other features stay on after turning ignition off , and still in vehicle won't work , and sometimes do work . These things happen when vehicle is either moving, or not moving in park . They happen both city driving, and highway as well. All of these crazy electrical problems began several months ago, and when in the vehicle and I am in park, and shut off ignition, and the doors won't unlock, the key fob won't work to unlock doors either, and I am trapped inside vehicle until someone is close enough to hear me yelling for help, and can hand them my keys out of sunroof in order to put it into lock on the door and manually unlock the door. I absolutely must have this fixed because nobody near my residence to either let me out of vehicle, or to call . Closest person I can call is over an hour away . I am on disability of 720.00 a month and can't afford this repair .

Gauges (fuel, battery and oil) quit working. So now the check engine light is on.
