2004- Factory fog lights not working??? Help!
 

My factory fog lights are not working, They aren't receiving any power. I checked the fuse and it is good! I checked for power at the fuse and there was 12v. I went ahead and replaced the Relay too! Still not working.

Please Help don't know what else to do!

1st thing to do, don't post in all bold.

2nd, do both of your high beams work ?

Is your truck a 2004 New Body style ( I made the assumption, but could be a bad idea ).

Did you do any modifications ?

Yes both High Beams work and yes it's the new body style!

I haven't made any mods to the lighting system, just audio!

Which fuse did you check ?

There is the fuse to the fog lamp relay coil, and the fog lamp relay.

When you pull the knob for the fog lamps, does the fog lamp icon on the switch illuminate ?

If you pull the fog lamp relay, you can jumper the fog lamps to check the fig lamp fuse to the fog lamps, and the bulbs.

Jumper pins 3 & 5 in the fog lamp relay socket.
