1995 5.8L E.B. fullsize Bronco. Electric windows.

Window will go down no problem, but won't go up from either the passenger side or the driver's side switch.

It is not a mechanical problem. (I previously rebuilt the window crank motors (i.e., "regulators") with new delrin barrels and everything was working great for a couple of years.) Now this electrical problem. I doubt it is a switch problem because it will go up if I push and release the up switch on and off intermittently for about a half an hour or so.

I know I will be taking the door panel off to inspect the wiring, but I thought I would post this if anyone has a suggestion for what I should be looking for.

 

Wiggle the wiring bundle inbetween the door jamb while holding the switch. More than likely the driver's side since it's usually used more. The wires can break from opening and closing the door for years.

 

Now that's news I can use! Thanks Dave! I will report back...
