well, i blew a fuse yesterday when the trailer i hooked to had a bad wire, so i replaced the fuse and went on. about an hour later i noticed i didnt have any brake lights. i stopped, checked everything and rode on home as i was in a hurry. when i got home i replaced the fuse and it blew it immediately. i checked all the wiring again and checked all the fuses (i.e., pulled them all out.) redid a few wires on the trailer and replaced the fuse again and it started working again. figured everything was good. got in the truck to go to walmart and the abs and brake light came on, but the lights still worked. also, the speedo quit working. this time it set a u0121 and a p0513. then this mornin the check engine light came on and now its got a p0500 and the cruise dont work, the speedo still dont work and im gettin pissed off. i took all the battery cables for about 3 mins over lunch and it did nothing. so now im home for the night and ive got the negatives off while i sleep. any help you guys!?!?!?!?!?!?!?!?!?!
