Welcome to AF, the tailite circuit boards were troublesome on the TB's check for voltage to the back of the sockets.

There was an official GM recall on TB/Envoy tail light circuit boards for I know '02-'03, maybe later years too. Any Chevy or GMC dealer oughtta be able to replace with updated circuit boards free of charge if it hasn't been done already.

I have a 2003 Z-71 and my break lights are out and I've changed bulbs and fuses and nothing works, do you know if there was a recall on the tail light circuit board?
