Rear brake lights & third light were staying on intermit. White smoke is now coming from steering wheel after the brake light switch was replaced today. This switch should have been to the subject prior recall of Blazer brake light and multi function break light switches. According to the repair shop, the old break light switch showed a burn mark. And, I kept the old part. We just drove it home and the break lights still stayed on and the smoking started which scared me so the shop has it once again this time to replace the multi- function switch. Note: that we were told by GM customer service that our Blazer was a few VIN numbers off the recall and wasn't effected by the break light recall.......... The problem was in at the time. The repair shop is now in the process of changing out the second switch at great cost to us.

On this occasion we had a heavy snow that day and as I was driving on the road I switched to 4 wheel drive. As I turned the corner, thinking I was in 4 wheel drive my car went out of control when it hit ice and I hit boulders and landed on a tree. Earlier when we purchased the car we noticed a light kept coming on that said 4wd. We called to have it looked at but were told it was nothing to worry about. My husband called GM and complained about the malfunction. After my car was taken to the dealership GM reps came out to see it and agreed there had been a malfunction in the 4wd system. They claim to have fixed it but my car has never been the same. I hurt my neck but since I don't have health insurance never did go to the doctor. They reimbursed us $600 for the repair. My problem is worrying that there are other vehicles out there that could have the same problem. …
I have a 2002 Blazer. Since I have owned the vehicle it has performed unsatisfactorily. The engine randomly makes roaring noise, the rpms rise and there is concomitant loss of power. I am told this is normal and that it is related to the fan clutch motor and a sensor that works erratically. The fan clutch has been replaced once and the vehicle has been in the shop several times. I have been involved in several near misses as the vehicle does not perform in a predictable manner. Chevrolet refuses to take any responsibility for this issue though I was offered $2000.00 toward the purchase/lease of another vehicle. In reviewing this website I note that there are several other complaints about this problem and in all cases GM/Chevrolet has refused to accept any responsibility. …
