Courtesy Lights Stopped Working, Auto headlights Stopped Working

After my runaround with my XK slipping into traction control, engine dropping back and finding it was a fuse
under the hood from an add on wire, nothing surprises me.

Electrical issues cause weird things to happen. It is all related.
Test all your fuses under the hood. You can use a continuity
tester across the open ends of the fuses.

Check the battery with a load on it.

Have you done anything to the Jeep recently?

Nick, is your AC cold? could it be leaking?

Don't forget the fuses under the dash.

Nick have you had problems with your dash lights flickering? Mine do but if I tap the multifunction switch it tends to stop. Multifuntions switch is the one on the left of the steering wheel. From my understanding it will cause all kinds of light problems within the jeep. It should be to hard to replace either I believe it is one screw. When I looked into it, the part was only like 70 bucks not to bad.

I'm docking him cool points if he asked without checking the fuses

Happens to the best of us.... I blew a fuse and my trailer lights weren't working. I didn't think to check the fuse at first, thought it was the harness since my tail lights worked. Little did I know the trailer harness was on a different circuit!

I had the same issue when i moved to texas pulling my car behind the xk. Didn't know why the trailer lights weren't working and everything else worked. Realized that with the tow package add on they had a whole different circuit for the trailer lights.

I'm going to check the fuses again, honestly I only checked the fuse box under the hood. I'll definitely check the interior fuse box. I was thinking it could be the multifunction switch as well. I removed it yesterday and cleaned the contact point. However if its failing cleaning won't fix it. When the auto headlamps/wipers stopped working it was so sudden. I went into the gas station with them working, left the gas station and they stopped working.

The only module I can think of is the Front Control Module.

As for the AC issue... I had the Jeep dealership look over the compressor, they said it operated fine. I'm wondering if its power steering related because the Hemi XK's have a hydraulic systems. I'm wondering if the power steering pump is failing, possibly causing it to stress harder when the AC is on.

Well check ALL the fuses especially with a sudden failure like that The dealer ship from what I understand in checking your AC will only check your high and low side pressure and the temp blowing out the vents. If all those are in range then its fine if there not standard answer you need a new compressor. What exactly is going on when you feel the engine struggling can you duplicate it?

That was the first thing I thought when I read his posts.
