Stock Fog Light issue

'03 stock TJ fog lights aren't working. Me and a friend have been trying to diagnose the issue. The lights are testing good. Getting no reading when testing the harness plug where they attach to the light harness. Fuse is good and relay is good, but getting no reading when testing the fuse port.
We think it may be the factory switch (or pull), but we haven't figured out how to test the stock switch.
Any ideas would be much appreciated.

First thing, get to the connector for the switch. Check that and make sure there are no issues. Mine was burnt and melted. If thats ok, you'll need to check for power to the switch and then power coming out when you pull the switch out. You can find a wiring diagram online. A google search should find one for you. I cant recall what website I got mine from. If you cant find any issues there, you may need to continue tracing the wiring down.
