Windows, wipers and dome light stopped working all at once on a 97 ford windstar. what cold be the cause? the fuses are good

Hello. It seems your Ford has a faulty master switch in the door panels (for the windows), a faulty door jamb switches (for the dome light), a malfunctioning multifunction switch (for the turn signal/windshield wipers). Good luck and keep me informed; if you want to.

the wiper fuses / relays are in the top left of the fusebox

sounds like a fuse or relay has gone bad

First, please review this article about fuses: Where's the fuse?

I have the same problem on my 1998 Ext:Cab F-150 the windows wont do anything and my dome light will not light up. Does anybody know what would be causeing this problem

This could be a combination of electrical issues, although i feel that the timing is coincidence in this case. When the combination is elec. windows, wipers, and dome lights this is indicative of the GEM module located behind your radio. The GEM (generic electronic module) is an electronic body control module that regulates electrical flow through a number of accessories.

These factory module boards are notorious for acting quirky by failing to ground intermittently until failing completely. I would be cautious in replacing ignition switches, locks, etc. as the issue can be also compounded by corrosion of the main battery ground wire in the engine compartment and which can cause frying of your under dash wiring into the main wiring harness which can get expensive (i speak from experience having had the exact same syptoms). My issues were that these symptoms occurred only in full ON. When in key BACK ACC mode, they disappeared.

New price for one of these modules is around $280-$300 and easily replaced.

Good Luck

i just had the same problem with my f 150 ( 1999), my wipers, washer fluid pump, dome light, door chime stopped, I went thur the manuals, Checked appropated fuses, even changed wiper motor, (nothing worked) out of much internet checking, talking to mechanics, I got frustrated, I started pulling all the fuses under the dash,, I pulled # 15 ,a 5 amp fuse, which has nothing to do with the wipers eletronics, it was a good fuse, when i put it back in, everything came back and working fine. nearest i can figure it was either loose or a dirty contact.

#15 fuse (5 amps) on my box is for : stop lamp switch,( speed control,brake shift interlock,ABS, pcm module inputs.gem module,RABS test connector)
this was just blind luck, maybe it will help you.

All these systems are controlled by the GEM, that is the Generic Electronic Module, have Kragen run a quick test and see if the system has codes, but most likely the Module is defective, it is located on top of the fuse panel to the left of the steering column. I have 30 years as a Ford tech so I am pretty darn sure of this diagnose.
