1998 GMC Sierra Signal Fuse Blowing

Hello,

I have a '98 GMC Sierra 1500 4X4 that keeps blowing the fuse (20A) in the circuit that controls the turn signals, back up lights, and brake/shift interlock. The hazard lights still work so the flasher relay is ok.

Any thoughts as to what I should be looking for?

Thanks!

Jim

It seems you have a short in either one of the lights or interlock. all are connected to the same fuse. trace the wiring from the fuse box back to the component. Using a test light test in between the wires. check for any obvious breaks in the wiring.

Blown dashboard light fuse


Since they are on different circuits I would say something in the wiring harness. It may be tough to find if it takes a few days or weeks for the problem to show up.
It could be a short in the harness in the column, or elsewhere.

Keep blowing turn b/u fuse as soon I turn on key 1993 gmc sierra


Check out your tail lights, sounds like they are grounding out. Remove the bulbs install a new fuse and install one bulb back on at a time and turn the key if one does not blow the fuse then the socket has worn out.

No turn signals


I would start by checking the fuses and if they are blown replace fuse.If it keeps blowing the fuse I would check your conections to make sure they are correct and not shorting out to ground.
