Okay so here’s my problem. While driving a few nights ago, my dash lights went out. Upon getting home I check the #14 fuse and it was fine. Then I noticed my parking lights were out. I looked in my service manual and checked fuse #8, it was shot. I replaced it and checked again, still no parking lights. Checked the fuse again and it was shot.

I used my meter to check voltage on the power side of the fuse, and it was fine. On the other side of the fuse I checked continuity to ground. It is grounded when I engage my parking lights. I pulled out my service manual again and tracked the pink/red wire to the headlight switch. At the headlight switch it changes to a 18BK/YL* wire. For those with Service manuals, this is on page 8W-86, for those without here’s a link. http://goo.gl/hqgCY

I have checked the parking lights by pulling them out and seeing if the circuit is still grounded. It is not the lights.

I also checked fuse 14 for ground. Somehow both sides of the fuse are grounded with the fuse out of it.

I have no idea where the ground is. My best guess is a melt between the headlight switch and front lights.

All information is appreciated.

If you have a trailer plug on the truck. Check it for being full of mud and corrided.

Glove box and ash tray illumination lights are also fed off the headlight switch and can cause problems......

Reach under the dash by the headlight switch and feel the wires for burns. Thats what was wrong with mine doing similar things yours is doing.
