Fixing Ford F150 Wiper after Failed GEM module 

Got a 97’ f150 from Grampa with 78k miles on it. From Las Vegas NV. Took it to Seattle and the GEM went out. They say probably the humidity. I only put 4300 miles on it myself. Truck looks brand new and runs that way. I couldn’t find a single shop to fix it. The last shop that told me it wasn’t fixable-I asked him “ So with all the rain we get here in Seattle and no wipers? You’re basically telling me the truck is Totalled Right? 😅 He said YUP! Thank you for your ingenuity Sir! 🙏🙏🌧️☔️👌

This is my answer,great job.I have 2002 f250 I junked computer to put distributor motor in haven't been able to figure out windshield wipers yet.This is what I need,Thank you for your hard work.

Great job, You can also leave the wiper unplugged from regular factory harness and hardwire the wiper motor direct to the Battery with one or 2 speeds direct to a toggle switch as wiper motors run on very little amps and alot of cars dont even have a relay for the wiper motors, would not even need an inline fuse all though I would just incase.

Went to Murray Ford dealership looking for just relays today for 1998 F-150 and they were talking about this truck like it was ancient of days. Wonder what they would think if went in looking for something for my 1966 F-250. But yes you have helped me as I know now to stop trying to fix it with relay replacements. Looks like I can get GEMs off the internet for less than a $100 to over $200 so I've some comparison shopping to do. And I might just come back to this video and wire the wipers like you have, it's just an old farm truck with no heat and a leaky AC. My issue started out with the power windows being flakey as hell then I noticed the issue was tied to the interior lights and at 1 point I thought the wipers were in sync with the issue too however I came to realize that the wipers weren't always tied to the windows&inside lights.

Good video helped me to get my wipers working again

Watched another video which showed there are actually several 5 Amp fuses that feed the GEM module, but according to the user manual have nothing to do with the wipers. Replacing one of the 5 Amp fuses fixed that guy's wiper issue.

Just a suggestion, although it sounds like the GEM IS shot, but there are like 5 - 5 AMP fuses that power that stupid thing, and they ALL have to be good for it to work. Gotta love engineers.

I think you meant 'washer pump' for tan/red momentary switch tap in, thanks for posting! Awesome!! I priced a GEM yesterday, dealer only item in our area if you can find it and retails for about $700.

Thank you so much I'm in battle the same problem except for my - lights came on when I jump because I jumped it out in the fuse panel box under the hood and my part don't work thank you so much I will try that and hopefully I'll be done with this I've been working on that for a while I saw it a few connectors in the gym that were loose still the same replace the switch going it was good I replace the headlight switch and dome lights and my dome light comes on when it starts really starts working whenever it wants Hotwire then my - light door ajar and my brake light flashes at me and dings so softly when I shut it off and didn't find parking this is the first thing that made sense to bypass at gem cuz everybody I talked to her I said there's nothing but problems and you must get the right one you just can't swallow them out with other ones

Man this shit is a god send shortcut to the solution

Hey, I followed this instruction exactly as you showed. It is not working for me, do you have any idea what I could be missing? Thanks in advance! (I know its been 4 yrs, hopefully you’ll respond!)

Hey I’ve been trying to diagnose an exact same truck. The windshield motor is good, switch is good, relays are good, and fuses good. Which leaves me to believe it’s the GEM. You have any way I can tell 100% it is the GEM? EDIT: it’s for a client and I’m kind of new to this. Just want to make sure he needs this part and not something else (a misdiagnoses). thanks

My 1997 f150 loses windows and wipers intermittently in winter. Sometimes they work in the auxiliary position, so I replaced the ignition module, no change. I just want to get the wipers working at low speed when they quit, the replacement GEM is not available and taking it out just to get at the wiring seems excessive. Where would I find an easier access to the wiper motor wires from under the dash?.,

on the wegos...you put the yellow white and red into one connector and then the blue grey and black onto the other connector right?...please advise!

I'm probably going to have to do the same thing here soon. Could I just use 2 switches? What happens if I leave those 2 wires connected but splice in the wires from the switch so if I fix the GEM they'll still work like normal? Is there not a way to feed power so the regular wiper switch still works?

I know it has to be a double throw but I don't understand why it needs to be a double pole.

Do you have a email for questions about the wipers on the Ford truck I have a 98 model f150 same issues

What a mess. Why not replace the module
