NHTSA complaint #10025805, filed 2003-07, 39,127 miles“I have a 2002 Chevrolet Blazer. The hazard lights and the brake lights on the body quit working. The brake light over the hatch still worked. The turn signals also were not affected. I checked fuses and light bulbs but both were fine. When I turned on the hazard lights there was a clicking sound coming out of my speaker, like there was a short in the wiring. I'm glad it didn't start a fire. I then did an online search for possible solutions to the problem and came across some recalls on my model describing the same problem. …”
NHTSA complaint #10300184, filed 2010-01, 85,876 miles“In march of 2010, my drivers side brake light went out but the bulb still lit up. It is a dual filament bulb, one for tail lights and the other for brake/turn signal. My mechanic investigated and the issue was a faulty switch for the brake light. This is a part that can only be purchased from the dealer. No aftermarket switches/circuit boards are available. The whole circuit board must be replaced. Again on 9/1/12, I was notified that both my brake lights are out. I called general motors and went to my local dealership only to be told my vehicle is not under a recall. …”
