So here goes again. another messed up wipers and dome light issue.

all the threads ive search through just seem to die before being fully resolved.

my specific problem

no wipers
no dome or map lights
no door chime

i used this thread with posts from sscully

https://www.f150online.com/forums/el...-problems.html

and i jumped the washer pump relay and the interior lamp relay and the dome light worked but no maps or reaction to the door being open or shut.
the washer pump worked with the jumper and the key in the on position.

my problem is idk where to go from here. i found a write up on swapping the GEM but idk if thats what i need to do for sure or where to get one.

any help is welcome im running out of time before it rains again in texas and i cant afford to not have a drivable truck.

 

to add my turn signals work as well as the high beam selector on the MFS which makes me think its not that

 

Like I said before jake, i have the same problem but only when its cold/wet out, my wipers will go on and off randomly.

 

so do they work currently? mine used to do it like that but recently they been off and its been cooler than normal but still warm in the sun

also what about the dome light

 

Yes they work, and they haven't done it since this spring but i am sure it will start again soon. I haven't had the dome light in the truck in about 3 weeks as the interior and headliner is out but i have never had any problems with it.

 

decided im gonna pull the GEM and fuse panel this afternoon and see whats up.

gonna probably need/order one of these

 

I had that problem with my old ranger, got a module from pick and pull that fixed it for $5

 

:O
Thats a fair amount of work to get the GEM out... There is suppose to be a way to test it as well. which leads to this next part.


Jake: I have read certain years had issues with moisture getting into the cab and dripping onto GEM, it was a known issue for certain years (found info on here one time)

I also assume you've verified fuses are good

 

yea i checked the fuses and the normally open relays and they all tested good.

i just pulled it out and it wasnt as bad as you would think but damn what a piece of junk the GEM is its so cheap idk how ford could charge 400 for one.

still dont know if its my problem or not

 

heres some pics of the connectors from the fuse box and the GEM













and the inside of a basic GEM module

 

Mine in my ranger looked like that..the dome light would blink on and off with the door open and the chime sounded weird, then the wipers would work every now and then and finally went out. Check if you have a pick and pull or a decent junk yard nearby no way i'd pay 400 for that pos

 

yea im on ebay and yards also. cant get one new cuz ford doesnt sell them anymore and your right a 5 yr old could make it haha

 

learn me how to remove that STUPID door chime.

 

The way I did it was to let water leak down and short out the GEM works pretty well in my truck hahha

 

Well put it all back together so I could drive the truck and it's still doing the same thing so I know I didn't break it any more but I'm still pissed
