Hi all. Having trouble with fuse #10 blowing on my 2002 E250 van. It controls the running lights, instrument panel light, and main light switch. I replaced the trailer hitch wiring harness under the rear bumper (which was corroded and looking crummy) and that solved the problem for roughly 30 minutes before the fuse blew again. Does anyone have access to the wiring diagram for a 2002 E250 so I can trace out what else might possibly be on that circuit?

 

Welcome to the site..

Multifunction switch is on the #10 fuse as well. Could be a wire chaff at the switch/column if you certain the trailer tow or lamp harness isn't the cause. I have the schematics but usually print to PDF which doesn't copy over well. Can print/scan/email if your stuck..

 

So I guess I should have looked a little harder....found this in the wires going down to the passenger side rear light setup.....amazing that the fuse doesn't blow anymore since I fixed it.......thanks for the help guys!

 

Good deal..

You get the schematics too?
