Re: 01 Taurus - Window/Door won't open
WD-40! Next time, they'll use duct tape...!
If the window motor/actuator and door locks work occasionally, then it's most likely a wiring problem... a short somewhere along the line. Make sure that the wiring connectors have no exposed wires, as moisture can accumulate. If you have a multimeter, test all the leads you can reach. Be sure to have an assistant run the locks or window while you test the wires.
Also check that the dealer properly installed the vapor barrier in the door. If not, you could always fabricate a replacement or tell the dealer to order you a new one. I find that they're good to remove/replace a few times, before they no longer stick on.
