Question about 2003 Chevrolet TrailBlazer
The brake light on the back door works, the turning signal works on both sides however the brake light, which is the same bulb as the turning signal, doesnt work,
Try checking the brake light switch attached to the brake pedal,very common problem. has about 5 contacts in it ,they all operate different things. If you have a scan tool with live data readings you can watch them all. also check fuses and bulbs ,but you say the signals work so that seems ok.
