Anyone know exactly which fuse is for the dome lights? TIA.

 

The dome lights arent on a fuse by themselves.If the fuse was out you would see various other things out as well.None the less I'll look in my owners manual tommorrow and see wich one it is and what else is on that circuit.If you have your owners manual you can look in the very back in the index for the word fuse and it'll tell you what page the fuse panel schematic is on and there it would be

 

My manual disapperaerd when I had some work done on the truck. Thanks for checking.

The plot thickens...my dome lights are out intermittently (for no apparent reason). In addition to the dome lights, the winshield wipers and lights on/ignition off warning "gong" also don't work. On the way home tonight I tried the overhead light and it worked. I then washed the windows with the wipers. I tried them again a minute later and they are out again. I'm stumped, any suggestions are greatly appreciated.

 

This all could be any number of problems.

Regarding your wipers, multifunction switches flaking out was a common concern. As was individual pins in the connectors to the switch backing out and making intermittent contact. Also, water entry into the central junction box/GEM module from a windshield leak can cause all kinds of havoc in '97-'03 F150s, Expeditions and Navigators. Did it rain recently before all these problems started?

 

My truck is not garaged and yes it has rained, however, I can't say exactly when or if it's related to the start of the problem. It wasn't raining yesterday...the wipers and dome lights worked once while I was out on the road. a possible culprit is a windshield leak into the GEM box? Any suggestions how to proceed from here? When the wipers don't work neither do the dome lights.

 

I too am having the same problem....no wipers and dome light....and it has rained recently......so do I need a new GEM module? I have had the original windshield replaced in the last couple of years....about six months ago....my radio shorted out and was fried....had to replace...
