My truck is blowing fuses when I turn on the lights. My dash, running lights and tag light! I did have two blown bulb's. So I changed them. I also changed the fuse . I did however have lights for about 5 min. Then they went out again. Please help!!

 

Have a look at the headlight switch, and connector......

 

The headlight switch is the only thing I haven't checked yet. I have removed both headlights and I have checked the wiring. I hope it's just the switch. I haven't checked to see if I even have trailer lights.

 

Yeah, where the trailer harness hits the rear harness is another problematic area.......
