98 GMC Z71 brake light, new bulb didn't fix
The passenger side brake light wasn't working, so we assumed it was the bulb.
Purchased a new bulb, installed it, and same result. The brake light, tail light, and turn
signal on that side do not work - even with new bulb. Suggestions?
its the fuse or relay for that side. also, check the wires for rust or shorts.
Carefully examine the IC board inside the tail light housing, it may have a broken or corroded contact, the boards are available from most parts stores.
Is there a brake switch? Or maybe a sensor? We have tried everything else.
