I recently changed both upper control arms on my 2002 f150 supercrew. While doing this, I noticed some wires hanging low and decided to tighten them up. When test driving my new install, I found the power windows along with the dome lights and running board lights no longer working but were prior to this. I noticed a wire I had secured touching my exhaust and the sheath had melted so I suspected this contact caused a fuse to blow. I have checked all fuses and swapped a couple of relays in the fuse box under the dash and spliced the wire with no resolution to the problem. Anyone have any suggestions? Please email me dennispattarozzi@gmail.com

 

How did you check the fuses? If you pulled them out and looked at them-that doesn't always work. A test light is the best way to check fuses in the circuit. I'd start there.

 

If you melted wires it's probably not gonna be just a fuse your gonna need to repair the melted wire and replace fuses and a test light is the best method to checking fuses so I agree with the above post it's a lot quicker and your able to test all fuses within minutes

 

It was only one wire that had melted and I have repaired it. Due to time, I have only been able to swap the #1 and #2 relays and the #4 and #5 relays in the dash fuse panel with no fix but will try testing with a tool as soon as I can. Any ideas on which relay may be the culprit? Hard to believe I'm having this much trouble solving what seems like an easy problem. Thanks
