The multi function switch located on the driver's side under the dash is problematic. The failure of the switch results in the rapid clicking noise that can be heard from behind the glove box on the passenger side. This is such a common problem I can not believe there is not a recall. This is the second gm of this model that my family has owned with the same problem.
1999 Chevrolet Blazer lights complaints
Page 2 of 2: complaints 11 to 32 of 32, newest first, as owners wrote them.
The multifunction switch has malfunctioned and caused a ticking under the dashboard.
The only continuing problem is this: most cars have a few items that are typical failure points, and we've found one. The combination switch (turn signal, cruise, wiper/washer, flasher) on the blazer is at the top of the list. We've found that it's very common for the flasher relay (under the dash, right side) to start clicking endlessly and audibly while no lights are flashing. Turns out the blazers combination switch is the problem. It's usually either failure in the turn signal stalk, or contact problems with the emergency flasher switch mounted on top of the steering column. If you remove the shroud, you'll find the switch assembly and turn signal stalk must be replaced as a unit. I don't know dealer prices, but the part on the aftermarket starts about $140 and goes up to $250 or so depending on the specific model and options (tilt, cruise, etc). Labor will add at least another hour if you can't tear down the steering column far enough to do it yourself. This problem is so common that it's a topic of discussion on blazer and s10 discussion boards, but don't expect a dealer adjustment. If it happens to you, expect to pay for a repair. In some cases owners have been able to spray generous amounts of contact cleaner into the switch and stop the relay clicking, but it's a very hit-or-miss proposition and you have to be lucky to avoid replacing the switch. However, if this is the biggest problem you ever have with the vehicle, life isn't that bad! Also this same switch causing the brake lights to not work. Similar to what has been already recalled for the 2000-2002 blazers. I have no brake lights and it will cost me $300 to repair due to a faulty switch.
1999 chevrolet blazer ls: approximately 120,000 miles (4-door /4wd) constant turn signal/hazard relay while vehicle is running. Odi id# 10043711 the multi-function switch seems to be the source as seen in many on-line forums/discussion groups. Most are dated, 2001-2003 time frame. I am just wondering if any resolution has been made for this issue. I am in the process of getting the vehicle looked at, while at the shop I was asked by the dealer to use opportunity to add my complaint to the odi id# 10043711 issue.
Dt: the contact complained about multiple problems with this vehicle. The 4-wheel drive actuation motor was replaced. The heater core became blocked and was flushed by the dealer. The steering box and pitman arm were replaced. Also, the front wheel bearings were replaced. The headlights became dim. The rear windshield wiper stopped working. The dealer performed numerous repairs, and could not offer an explanation as to why these problems occurred at such low mileage. The vehicle is remained at the dealer awaiting repairs on the rear windshield wiper. Also, replaced loose front hubs.
1999 chevrolet blazer 2wd / 4 door bought used 5/2004. Sudden onset of uncontrollable "clicking" of turn signal flasher unit / controller switch. This has continued for the last month. Smoke was recently produced from steering column. Turn signal noise is not only annoying, it is distracting and potentially unsafe, especially when driving in traffic near crowded intersections. I have been informed that 2000-2002 blazers have been recalled for signal controller problems, but not 1999. Gm holds that the malfunctioning signal controller is not a safety problem, I disagree.
When turning in either direction the turn signals continued to flash after a complete turn. Please provide additional information.
The hazard warning switch has a defect which causes the hazard flasher to function while riding down the road. The lights do not come on, but you can here the flasher clicking, and it gets worse over time. The potential exists for the switch to reach the point where the hazard flashers come on during normal driving.
The turn signal, hazard light and brake light engaged prematurely due to a malfunction within multi-function switch. This occurred without warning and could cause an accident. *ak *sc the manufacturer issued a recall, however the consumers year of vehicle was not included.
Following is part of the background first submitted 9/6 to chevy for a major safety issue with our 1999 blazer ... Closely related to a recent gm recall for faulty hazard and turn signal lights. Our hazard/blinker flasher just started (9/1) turning on/clicking intermittently for no apparent reason ... Doing so randomly about half the time. This concerns us for our safety ... As we are now constantly making both kinds of major safety errors that can happen with this defect: we frequently think the blinkers are on for a turn were making, when in reality they are not, but the flasher is clicking just like they are on, so we wrongly think they are on. The other error is that we have accidentally turned the blinkers on and don't realize it since the flashing noise is happening so much. The major reason for our concern is a statement from our local chevy service tech around our exact issue ... As our exact concerns/issues stem from a well known/documented safety issue with blazers (per the words of our chevy service tech around our exact issue, & this has been a big/major problem with blazers & ... And '90% of the time a defective multi-function switch/contacts is responsible for the identical symptoms we were experiencing', and indeed unique to chevy/gmc.) given how emphatic/honest the service tech was with us, you should be able to readily substantiate his statement through chevy's records around repairs for this problem. As such, our safety issue is clearly: a well known/documented safety design issue with blazers, and related to the recent safety recall for gm flashers; with our blazer only a year off of the recalled vehicle age; unique to chevy, and as such, not 'normal wear/tear that should be expected'). We very much appreciate the opportunity to forward our concerns to your agency, and look forward to hearing from you on your latitude to pursue this further after continual rejections from chevy. Thank you in advance. *ak *jb
My car has had two recliner mechanizms break in 2 years. My security lights come on for no reason,my paint is checking and peeling.now it appears that my control arm and lower ball joint were failing at 85,000 miles.*ak at about 70,000 miles my 4wheel drive would slip in and out at freeway speed. I have a 1999 chevy blazer,4dr, completely maintained and driven with care.
Consumer advised that the vehicle's head, tail and interior lights will brighten and dim without warning while driving. Finally on 11-4-02 all vehicle lights failed completely. Ts
Consumer states almost rear ended when brake lights were inoperative. Third light works but other two work on and off. Dealer found multifunction switch is shorted out.
On several occasions upon filling fuel tank with gas, smell continues to enter into vehicle, took vehicle to dealer. *ak dealer tightened loose gas cap, advised consumer not to continue filling vehicle after pump clicks off, replaced evaporative canister and evaporative vent solenoid, fuel tank module, removed left quarter trim and sealed, removed fuel tank sender, and filler tube assembly, diagnosed fuel and exhaust system, dealer found body seams in filler tube assembly leaking fumes, cause still unknown, dome light stays on all the time, dealer replaced right and left door jam switches, heating and air conditioning now hot at times or too hot, dealer replaced rad cap and polished neck, serpentine belt noisy, replaced serpintine belt, wipers won't clear and are noisy, replaced wiper inserts.
Lights on dashboard for 4x4/2x4 began flashing while driving. Vehicle was in normal mode. Also, service 4 wd drive light came on. Took to country cehvrolet in warrenton, va-advised of 4wd problem also advised check engine light comes on, headlights dim occassionally when driving. In addition, when engine is turned off and radio remains on, battery died 2 times. Mechanic found circuit 1133 shorted to steering column bracket, replaced wire. Problem reoccurred immediately. Returned to country chev-rechecked and replaced wiring. 4wd lights still flash. Unable to determine trouble.
Vehicle lighting system, including dash, interior lights, head lights, etc, will blink erradically. The manufacturer is aware of the problem, and has indicated that it could be the ABS system malfunctioning, or something else, they are unsure. I have contacted gm on several occasions for updates. They provide nothing.
Problem with lane change feature in turn signal switch. Lane change signal will operate front or rear signal indicator indepentalty or just give audio acknowledge for flash with no indicators illuminated. In many cases the only indication is the flasher will flash at a more rapid rate. Many gm cars and trucks have this problem and it is very dangerous because the operator does not know that an indicator is not illuminated because the dash indicator is operating and one or more outside (front or rear) indicators will not be operating.
Floor vents under dashboard put out very hot air, when controls are set to off. Also, daytime running lights do not have an override switch, which would allow the driver to turn lights off.
While driving with headlights on, instrument lights and the headlights would go off without prior warning. This could happen from time to time.
Daytime running lamps were standard safety feature. Began working intermittenly, took to ealer for sevice. They disconnected, gmc rep said would not fix due to egineered improperly at factory.
Standard daytime running light were not installed because manufaturer felt they were too close to the turn signal which would confuse motorist which lights were being used. Nlm
Daytime running lamps are listed on the invoice as a safety feature and dealer states that they were removed by general motors and not to be activated, even though dealer has attempted to do so.
