Recently the doom light and cargo light fuse blew, of course with this fuse blown the windows wont work. I replaced the fuse and it blew again. After a few days I put another fuse in and it lasted for about three days and blew again. After futher checking the doom light relay(under the dash drivers side) was getting hot. I replacer it but the fuse is still blowning as soon as I install it. I removed the relay and the fuse dosen't blow, this lets my windows work. Any ideas.

 

Try a meter on it and see if you're getting a short. Also, test the relay seperate from the rest of the circuit to see if its flakey.

Sounds like your dome light is "the light of doom!" The light in my truck (1998 F150 4x2 4.2L) starting turning off and on by itself... then would not turn off at all. I removed the bulb as I didn't want to have to subject myself to an all day trip to the Ford dealership for just a bulb. Will have it looked at on the next scheduled maintenance. Good luck and best regards!

From your description, it sounds like something on the circuit that is fed through the relay's contacts is the problem.
Wasn't there some problem with wiring at the dome light on some run of the trucks? Seems I vaguely remember something about that. Might want to do a TSB search on it.

 

Thanks for the info... I wasn't aware there was a bulletin about the light and will look for it.
Best regards...

I checked all TSBs relating to 1998 F150 dome lights and could only find info on running lights for Canadian built trucks. I'll keep searching.
