Multi- function switch problem. The wipers quit working during the rain. In the past I have spoken to dealer service managers and they said a lot of complaints have been made about the multi function switch that controls the wiper delay but there has been no recalls made on it. Mostly what happens is the wipers will not turn off with the switch, the ignition has to be turned off to turn off the wipers. The concern is the wiper stopping during heavy rain causing loss of visibility. This has been occurring for years, I just became aware of this route of complaint process. The replacement of the multi function switch is expensive. Clicking is also heard at times due to the switch, a service manager has said the multi- function switch causes this also. The 10 for number of failures is the minimum number of times I can remember the wipers stopped when operating.

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 s10 Blazer started vehicle, drove down driveway out on to street. Smelled smoke, returned home. Found back of drivers seat on fire, put out with garden hose. Wiring under drivers seat started on fire? we do not have heated or power seats on vehicle and we don't smoke. Damage was burned seat, carpet, rear floor mat, melted wiring. The vehicle does have the hazard/blinker that turns on intermittently for no apparent reason. Don't know if this is related.

Blinker noise persists even when blinkers are turned off. Sound disapears after engaging brake pedal then persists when break pedal is released. In a heavy rain storm, had to use windshield wipers and after a few minutes of use white smoke came from the steering column. Talked to a gm mechanic who told me that this problem could cause my airbag to deploy - a real liability. Called gm to explain the problem & possible liability of airbag deployment (case #1-333564043) & was told that because of the Blazer being a 1998 there may be nonthing they can do. The same multi-function switch was made in mexico for 1998-2001 models and if it disfunctions can cause break lights not to work as well as major electrical issues like airbag deployment or fire - wouldn't this be a recall for all models that have the part?.

The turn signal on my1998 chevy Blazer won't stop clicking. I've already replaced the combination flasher/signal part that's behind the glove box with no result. Today I saw wisps of smoke coming from the steering console. I checked the fuses and they are fine. I'm afraid my car is going to catch on fire!.

Failure Date: 08/03/2004

Had drivers side door rehung due to sagging. Shortly after that my interior lights began to malfunction and my auto reserve power(allows radio, interior lights and power windows to operate for 15 minutes after engine shutoff) began to work "occasionally". Also, the windshield wipers operate randomly - juggling the wires under the hood helps to make them run . Now, at 3:30am this morning, I realize that my headlights are not operating, checked in the morning and the daytime running lights work, but when you manually turn the headlamps on, the daylights go out and you have no headlights on.

There is a bad design in the bundle of wiring above transmission with plastic ring holding bundle, this bundle is not attached to anything allowing move rub till they short out in the Chevrolet Blazers, mine is a 1997. My Blazer wiring caused my transmission switch to short out and I was first told I needed a new transmission so I took it for second opinion, the second shop cut the wire from the bundle, rerouted it from transmission switch and the transmission switch worked. Other wires in the same bundle caused shorts through out all wiring causing a constant draw of electric and running battery down. When a fuse is removed it breaks the circuit and battery does not run down. The shorted wiring caused day lights to not work, interior lights to stay on unless I pulled the fuse and numerous other electrical problems. This is the second time I have had it in the shop for the same thing. They are now dropping the transmission to get to the bundle of wires to fix shorts and I am taking pictures of all of this. The shop had two other Blazers in at the same time for the same problem. I will also take pictures of those Blazers, one of the Blazers is the shop owners wife. The shops are telling me it should be a recall. I plan to report this to as many agencies as possible and interview as many shops as possible about this problem, I believe it is a fire hazard since it shorts out. The wiring bundle is also connected to the fuel pump at the gas tank. I hope Chevrolet will act soon and take responsibility for this problem. There should be a recall on this. I have also had it in nix Chevrolet where I bought it and the ac did not work, they have worked on the ac 8 times and totally rebuilt everything and I still do not have ac???? they said they will look at it again. I also have numerous recalls I will have to have fixed. I have had so much trouble with this vehicle since I bought it, it's been in the shop more than I have got to drive it. I will never buy Chevrolet again.

Brake lights will not work when applying brakes. Bulbs and fuses are all ok, hazard flasher when flashing causes an electrical static sound under dash and when wiggling the hazard flasher switch, brake lights will work and come on. I also own a 1996 Chevrolet Blazer that had the same problem and was repaired at bob hook Chevrolet 09/07/99 invoice no. 156312. Very little chance that I own two of the same vehicles five years apart and same defect happens to both. This is a serious safety problem that needs to be recalled before accidents occur because the vehicle behind didn't see vehicle in front stop. I am not only concerned about my family being safe but for the safety of others! why would the dealer service shop tell me that the part will have to be ordered and there is a national back order on that part but to continue to drive the vehicle? I have contacted gm. And filed a complaint # c05965366 and they said; we will do the best we can to get the part shipped. Please help get this defect recalled so potential accidents can be avoid.

Our Blazer caught on fire while driving down the interstate. We were traveling at 75 mph using the cruise control. The steering wheel jerked a little and we immediately saw black smoke coming from the rear of the vehicle. White smoke was coming out of the passenger side under the hood. We pulled over to the side of the road and turned off the engine. As we were pulling off the road the computer controlled dash instruments started to malfunction, but at no time did the engine appear to have problems. As soon as we pulled over we realized we had a fire & immediately called 911. Someone stopped with a small fire extinguisher to try a stop the flames. The fire appeared to be located towards the dash on the passenger side down in the middle or lower area of the engine compartment. The fire was so hot that it went through the passenger side below the dash board and entered the cab of Blazer. At that point we had nothing left to extinguish the fire and shut all the doors and the hood to try & contain & smother the fire. We then waited for help. We were 150 miles from home when this happened on a rural stretch of interstate (the nearest town was 18 miles away). We would like an investigation to find our what happened to our vehicle. Our insurance company won't help. We have contacted the dealer and we are still waiting for the general manager to call back. We contacted gm and got as far as the product allegation resolution team. They sent a letter stating "our investigation revealed no evidence to support product allegation". We called them back and they admitted that they never looked at the vehicle. He said he followed procedures according to company policy (we have requested a copy of that policy). Our vehicle is still where it was originally towed in March. We would appreciate your help in this matter. Thank you.

I wanted to report this defect on my 1996 Blazer because it is the exact same defect I have just reported on my 2001 Blazer. What are the odds this only happened to me on my vehicles five years apart? this electrical wiring defect could cause a vehicle to catch fire anong other things. I have had the repair completed on my 1996 Blazer but it appears parts are not readily available to repair my 2001 Blazer. I would guess several 1000 other Blazers are having the same problem. Please help get this defect a recall so potential accidents can be avoided.
