Question about 2000 GMC New Sierra 1500
Fuse on turn signal and back up light (15 amp) keeps blowing when I turn on the ignition switch. What started this problem is a short that melted the fuse so it appears I have a grounding problem. I replaced the turn signal switch under the steering wheel but still the fuse blows. I think it might be the back up switch on the wire to the transmission back up module but do not know what wires they are. No obvious wires melted on the main control box on firewall or on the back of the fuse panel. Need help looking for a short or some kind or some direction to look for. Thanks
Check the flasher unit, the transmission module unit should ground the backup lights, so I don't think its that. installed any new electronics or drilled any holes?

Have you checked if the globes are shorted?
