Question about 2003 GMC Envoy
I have replaced the license plate lights on my 2003 envoy ...and they still don't work ..does any one know if it's a fuse or a short
The licence plate lights are in the same line as your tail light wiring assembly. I assume your tail lights are working or you would have got a ticket for that. The wire is either cut, broken or unhooked from the tail light wires (which usually are brown). If you can not find the problem, you can always run a new wire to the tail light wire from your licence plate wire. Then they should work.
Your other problem is that the license plate ground is rusty & not grounding, which would also not let them work, so you should probably check that first. Rick

SOURCE: # 4 fuse blew out,
I KNOW YOU HAVE AN ELECTRICAL SHORT.WAS AN ALARM INSTALLED OR ANY OTHER TYPE OF ACCESSORY? CHECK WITH DODGE TO FIND OUT ABOUT A RECALL.IF SOMETHING WAS INSTALLED, TAKE IT BACK THERE TO STRAIGHTEN IT OUT IF NOT HAVE A AUTO TECHNICIAN CHECK IT FOR YOU.

First chk. all fuses and bulbs. There is a backup light switch under dash either on steering colume or someplace close. plate lights should be hooked in with running lights, If bulbs are ok chk for wire unhooked or bad ground. can't help on diagram.

theres usually a pressure switch behind the brake pedal, sometimes the plastic hex nut rattles loose and you have to retighten it.
