Yesterday I changed out the stock no good battery cables to 2 gauge wire. I put everything back in the exact same spot. Then I changed my door speakers out to Audiobahn speakers. When I was driving to my girlfriends house the music stopped, my heater stopped, the vent doesn't blow air anymore, the a/c compressor won't turn anymore (but the a/c didn't work before, but i could hear the compressor turn and stop), my windows won't roll up my windshield wipers don't work anymore, defroster doesn't work anymore, my turn signals don't work anymore, and my reverse lights don't come on now. But my brake lights still work, running lights still work, headlights and high beams still work, and the flood lights i put on it still work, my in-dash trailer brake system still lights up when i hit the brakes, and my hazards still work. i tested all the fuses in the fuse panel and there's no power to all but 4, but none of them are blown. All the wires on the solenoid are still hot and the truck still starts no problem.


So over all what the hell happened to my truck??????

 

Check the fusible links at the selinoid you may have blown one of those.

 

Depending on the year model of your truck you may have a fuse panel under the hood, driver's side, on top of the inner fender. Check there too.
