I Have A 1997 F150 5.4l. My Truck Has A Mind Of Its Own. At Will My Dome Lights, Wipers, And Windows Will Quit Working Then Magically Start Working Later All By Itself. Driving Me Crazy, Does Anyone Have Any Suggestions

 

im not real good at this kind of stuff, but i assume you have checked the fuse box? and check the fuse for that stuff? maybe its lose or theres water in there or something

 

Sounds like you have a 'GEM' problem. This can be caused by the windshield leaking on the driver side. The GEM controls the interior functions and is located behind the fuse block under the dash. Do a search for more info.

 

I Have Been Doing Some Research, Seems To Sound Like A Gem Problem. Thank-you For Your Input. DoYou Know Where Exactly Yhe Water May Be Coming In From The Wipers?

 

Most likely the windshield. This has been a big problem with the 97-03.

 

Thank All Yall For The Help. It Ended Up Being A Combination Problem. The Fuse Block And The Gem Module. Replaced The Items And The Truck Seems To Be Working Fine.

 

Great and thanks for letting us know.

 

are you sure it was both. i think i have the same problem but dont want to buy both i think it might just be the fuse box. and with the new gem did you have to get the computer re-flashed.
