^^^ I'll make sure to check the ground for the front end harness. It's supposed to be grounded on the radiator support, so I don't see any reason it would be messed with if the headlight panel was all that was replaced, but I'll check regardless.

Also, the issue as to why everything was not working or working funny was because of a blown fuse. Had to actually remove the CLK-ACC-CTSY glass fuse to see the gap and that it had blown. When I glanced at it initially, it looked fine. After replacing it, everything now works like it should - in fact, my radio reception is clearer now than it was before on various channels. It's weird how a blown fuse on one bank of the electrical system can affect devices that operate off another bank, and that how some very minimal draw devices on the bank the blown fuse is for can still work in the presence of a blown fuse such as the glovebox light. Either way, after replacing the fuse everything works again. I also replaced the dome light bulb just in case.

I'm well aware a blown fuse is a symptom rather than a cause, but I'm not really sure what could have caused the fusion to blow other than just bad luck or age. Maybe that bulb for the dome light shorted or something, I dunno.
