Defogger problems of the 1999 Ford Escort

I was driving with my heater fan running and began to get a burning smell. The fan then quit running. When I investigated to find out why the fan no longer would work, I found the electrical connection for the fan motor had melted and looked burnt as though it may have smoldered. I have that piece available for inspection if needed.

Tape gets stuck in tape deck and won't play or eject. It just makes a whining noise. Heater/defrost doesn't want to work in extremely cold conditions.

Water is blowing out of a/c and air vents and dropping on floorboard. Cause unknown. Dealer does not know what the problem is or how to correct it.

When defrosting my windshield, the section directly in front of me never fully defrosts. When the sun hits it it glares so much that I cannot see anything. Dealership found nothing wrong. It only defrosts from the inside if I wipe it off, but otherwise it stays fogged up.
