Ok got a 02 F250 super duty 7.3 6spd single cab an got few questions:

1st: When got truck had after market aluminum wheels with 315s an little lift. Pulled that off back to stock I went with 1.5" leveling kit. Found set 16" steel with set oem lugnuts and ive tried 2 different sets center caps. They will not stay on. Tried set with 4 stays an set with 8 stays. What I need do?

2nd: My fog lamps work sometime. I was checking wiring on back headlight switch and had power probe and was checking yellow wire for power cause trying to mod so fog stay on with brights, anyway done something now dont have any fogs ever. Is it common for headlight switch go bad? Cause to test it went to friend that has 03, he said his lights dont wrk either. I said maybe u got blower bulbs, I know mine good. So switched switches and still no fogs.

3rd: At random cruise dont work. Once was as I stepped in I caught ebake and didn't work and caught it. Also noticed when does work the green light dont come on every time.
Help greatly appreciated.

 

I think you pull out on the switch with the lights on to engage the fog lights. I could be wrong. The center caps should pop on no problem. I haven't had an issue with super duty headlight switches but I did have a Ford Taurus that nearly caught on fire because of a faulty head light switch

 

o I know the fog come on when u pull out on headlight switch. Wonder there a test I can do to confirm the switch faulty, cause there expensive. An on center caps its like chrome cover on wheel sticky out to far.
