I believe the heated mirrors are automatic? As in they turn on all the time when you start the vehicle... my old Chrysler Daytona worked like that. Put a hand on one at start to see?
Light for the rear wiper? You mean in the switch the light doesnt work correct? My lights dont work for those switches either, tried replacing the bulb, Chrysler no longer has them no one sells them aftermarket. Bought one from an electronics shop... couldnt make it work either. Gave up.
Check your fuses...
Probably, you can find replacements online reasonably cheap, try Ebay.
They have a habit of failing at the condensor under the dash. They are held in place by plastic pull through clips that have a tendency to wear through the fins I am told. BIG job to replace too. Not hard, just time consuming. Mine leaked there, found it by adding flourescent dye to the recharge and running the AC. You can then hit it with a UV or Black Light and see the leak. Read this thread...pics appear to be moved, too bad was step by stem and the best writeup I have found.

Sadly, I do not have heated leather seats...so I cannot comment. Check your wiring, might be a bad connection?
Replace them... cheap enough, I think you can get them online for around $30.00 each?
Keep the aftermarket one... the stock head units suck.
Oh and you Definitely have a LTD and not a Classic. You likely have ABS too if you have cruise as I believe they came as a convenience package? If you have ABS, you have a 35 and not an 8.25. Looks like a sweet jeap, and for what it is worth, I love the Chrome on that Red!
