Hi all, I have a question that I have been dealing with and it has driven me nuts. My 88 Bronco was working fine until my son plugged in a friends trailer to haul 4-wheelers. ever since then the headlights will not work with the switch all the way out, you have to pull it out and then push it back a bit to make everything work, same situation on the parking lights. Also, the wipers will not work on low or intermittent with the engine running, but fine with the engine off. I have pulled off the trailer wiring and any accessories, checked every fuse, replaced the headlight switch, you name it, but the problems are still there. Can anyone help me out on what to check next before i jsut set it on fire?
thanks in advance! Oh, also, the truck seems to smoke now and seem to be burning rich and never has before.....
