All of my power windows in my 1998 ford expedition will not go up or down,the mechanic at the ford dealer said it could be a bad module which would cost 700 to fix? They said the applied power directly to teh window switch and the windows then worked? I think it is simply a bad fuse somewhere?

Call a dealer ask to talk to a mechanic.
Be short, clear and polite. They will give a good answer. If one dealer does not get it done there are plenty of others to call.

This 1997 Ford F150 needs the GEM module changed due to multiple conditions. To see testing that lead to this repair please click here. The GEM module is located t the rear of the interior fuse box.

The first step is to remove the trim panel that covers the gap between the upper side of the steering column and the dash. It just unsnaps from the dash. It makes it a little easier to remove if you move the shifter all the way down to drive 1.

With that out of the way the lower dash cover can now be removed. Most of the screws have 7 mm heads but there are two that have 8 mm heads.

Those two are at the lower edge of the fuse box.

One wiring harness needs to be disconnected from the panel.

Now the screws for the fuse box can be removed.

The wiring harnesses can be removed from the back of the fuse box. Two 10 mm headed bolts at the center of each connector.


Next remove the tube brace from around the bottom of the steering column. Four fasteners with 13 mm heads.


Now wiggle, pry and twist the fuse box and GEM module assembly down.

After the assembly is down far enough unplug the remaining harness connectors from the GEM module.

Almost there.

The assembly is now free of the vehicle.

The GEM module is held to the back of the fuse box by three phillips headed screws.

Easy to remove Now.

With the three screws removed the GEM unplugs from the back of the fuse box.

I put it all back together and checked my repair for power to the driver's power window switch.

I suggtes visit your dealer.

if all your power windows have an issue it has to be a fuse issue, the chances of all your motors being bad at the same time is unlikely, some times it can be the contacts in the switch , however again if all of them are out , and went out at the same time my guess is a fuse

If you smell antifreeze it may be 3 possibilities: 1. you may have a leaking hose/hose connector , or water pump. 2. your heater core is bad and needs replaced. Unless you know what you are doing I would highly suggest taking to dealer for heater core replacement. The dash and steering colum has to be removed to get to the heater core. This is not an easy job believe me (about-900-1200 job). If you have your heater core replaced then also replace the climate control door. This is good preventative maintenance and also a a dollar saver. I would have a pressure check run on your radiator as a first thought. All you may have is a bad hose and that can easily be replaced.

Either the switch is bad, or the motor athat goes forward and back is bad. A mechanic will need to check it with a diagram to determine which.

what happened in my 2002 Exp, because they slam the door, the wire broke off switch that power downs the window, but if not that the switch mite be screwed, or you mite have a broken in the door where it opens an closes....

Yes. You have to take the car to a ford dealer and have the new key programmed. This should solve your problem. Good luck.

check valve for pump is bad leaking back thru,that is if both bags are deflating

it could be but lets start with the obvious
the switch
the fuse
burnt up wireing in side window
bad ground
