Two problems related to brake light switch have been reported for the 2002 Chevrolet Trailblazer. The most recently reported issues are listed below.
A couple months ago my right rear brake light went out. And I replaced it. Then last week my truck did not start. And I realized I had a dead battery, but nothing had been left on. I then discovered my left rear brake light had burned out . No sooner before I could replace it my right rear , the center rear and the left rear all stay on like the brake is applied . This is very unsafe to operate and am concerned on how I am going to get this repaired let alone get it to a automotive shop.
I experienced total brake light failure with no warning or indication on a 2002 Chevrolet Trailblazer with 44,000 miles (which I take very good care of)! I was sitting at a stop light and the nice driver behind me informed me that my car has no brake lights. He said that happens a lot with these cars, the brake light switch blows. I wish I had more time to talk to him, bill estes Chevrolet in indianapolis charged me 200 dollars to diagnose the problem and put electrical tape around it. I nearly got rear ended driving to the dealer with my hazard lights on! at the dealer, the mechanic explained to me that when I applied the brake, the brake lamp switch harness was pinched between the bracket and something else. The documentation from the dealer reads like this: diag as shorted brake lamp switch harness aproximately 3" from brake lampswitch. Repair harness and reroute away from braket. The only parts described were 'shop supplies' (electrical tape?). The customer service rep explained to me that they don't design these cars; indicating, that he thought it was a design issue. While I'm disappointed that we had to spend 189. 54 to get the thing fixed, I am thankful that no one was hurt - I transport my 3 year old twins in this car. I am very disappointed in this issue and concerned for the safety for other drivers. I decided to check out the NHTSA website after I read on an internet chat room that there was consideration to ordering gm to recall the cars for this issue.
