2001 XJ Factory Fog Lights Not Working

I've looked around this forum and a whole bunch of others and all the solutions I have tried weren't any good. I have cleaned the switch of any corrosion so that is out of the equation. Also, the relays and fuse for the fog lights are good. I did notice when I opened the bottom of the fog light that there was one blue wire that was connected to the bulb and another black one that a rusted out connector. I tried connecting the bulb to both of the wires and nothing happened. Any help with this?

Yes. I just bought new ones to make sure that wasn't the problem.

Are you getting voltage to the lights? Switch work?

Switch works and I know there is power between one of the two wires because when I contacted both wires with the contact on the light bulb it made a spark at the contact and the bulb started to glow and went out.

You can clean the corrosion out of the switch, but it can still fail. (I went nuts with this on my Wrangler, cleaned all the corrosion out with a wire brush, it turned out to be the switch), also, trace the wires from end to end, I had one ground out on another lead shorted the darn things out.
Good luck

There do not appear to be any shorts. Any other solutions? What is the second spade connector for? It has black insulation and has some rusted up piece of metal in it. Is that ground or the original connector? Is the cleaner looking blue wire new or extra?

Odds are the black connector ground is your problem. If I'm not mistaken the blue wire goes to your low beam power so the fogs turn off when highbeams are activated. Ground is probably the most common problem with any wiring issues.

How do I ground the black wire? I accidentally touched the two wires together and I blew a fuse. It is getting very foggy here right now....

By touching the two wires you grounded 12 V which will pop a fuse every time. Find a place to screw the black wire to the frame or chassis or a clean spot on the body no paint, no rust .. a nice clean spot. there are existing holes in front Behind the bumper

I would clean the ground. If you know there's power at the lights it could be the connectors for the light bulbs. Or any connector after the lights.
