Re: power windows issue
The problem maybe nothing more than replacing the switch assembly. Fords ( I have had 5 Crown Vics, 2 Explorers, 2 F-150's...you get the picture) all seem to have that issue. Water drips down, get inside the switch and eventually corrodes the contacts. The last OEM switch I bought from Ford was around $40.00. Start to finish is about 1/2 hour. IIRC, all you need is a phillips head screw driver. Not sure if you have to remove the door panel or not. On my Crown Vic CVPI, I didnt have to. Popped it up, unscrew the 2 screws, remove wiring harness, replace with new one, screw back together and pop back in.
I hope this helps
