I haven't done anything to the XK lately.

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.
