Just like the title says yesterday they both just stopped working at the same time. But the door locks still work. I checked all the fuses they are all still good. Any ideas??? Thanks.

Maybe the GEM module is staring to die?

 

[7.3psd1999]

What's the gem module?

 

[Blue2002]

Generic Electronic/electric Module. It controls the body/chassis electrical components. Alot of the Superduty's had a problem with water leaking past the A-pillar seal and dripping onto/into the GEM. Causes a slow death from corrosion or shorting. It will be the black box behind your fuse panel under your steering column.

Okay thanks. Would that just cause the windows to quit like that and everything else work?

 

[Blue2002]

It is a possibility. It may also be you window switch.

before you throw parts at it, take out your switches and spray them inside and out with WD-40...it doesnt hurt them a bit, and it clears out any junk thats in them...i had to do it to my OBS last year and they are still workin great!

I got a new window switch already and nothing? Is there a relay for the windows some where? I really need to get my truck back on the road.

Mine did that and it ended up being the mirror and dome light fuse that blew and caused windows not work.

if the drivers side switch goes out both windows quit working, but when it goes it usually pops the fuse as well. if the passengers side switch dies, only the passengers side quits(unless it pops the fuse,then both quit) whether using drivers switch or passengers switch.

The fuse it usually pops is the One under the hood the big 30amp fuse right? Or is there another fuse for the windows I couldn't fine another one in the owners Mannuel

Thanks guys it ended up being the dome light fuse blew. Who would have ever thought

 

[markwemple]

I'm in the same boat. Dome light is working. Tried swapping switches. NO luck. It isn't the fuse. I have a 99 CC and all the windows aren't working and it happened all of a sudden all at once. Ideas??

I have a wiring diagram if that would help you at all. It could be a few different things. I would have to email it though. Let me know.

Check the wiring in the drivers side door jam coming from the under dash area. Mine was broken from open/closing door so often.

This just happened to mine. Driver's window only. I can hear a click under the dash when I push the window button.

check for power at drivers master control switch
the Gem module has nothing to do with power windows

Something tells me that it’s more likely to be the master control in turn signal. I lost my rear doors and the passenger side struggles now. 4x4 also isn’t lighting up. Last time something like this happened was the turn signal assembly in the ford ranger. Gonna give that a try.
