I noticed last night while driving home that my fog lights were not working. I have a 06 Supercrew. When I pull the switch out the amber light to indicate the lights are on does not light up. I checked Relay R202 under the dash and it is good. There is another relay under the hood on the driver side but I am not sure how to test it, no reference. I am wondering if anyone else has had this problem, they just stopped working, I have not done any work on the truck in a while.

Thanks

 

If youve checked relays and fuses, next place I'd check would be loose wires. Gotta voltmeter?

 

It's corrosion in the pigtail that runs from the harness to the lights, Just had my 07 done under warranty, 2 new lights and 2 new tails about 10" long. It was only $88.00 If I would have had to pay.

 

I could get a DMM from a friend but I think I am just going to take it to the dealer truck is still under warranty until June. Maybe Ill have them replace those 50/50 window switches too.
