So I bought the lights that go into the panel that light up the heater controls, from amazon (a 3 dollar purchase, and they AUTOMATICALLY signed me up for amazon prime, another 100 bucks, be weary when ordering from the fkers). Anyway, one of the lights will light up like it is supposed to for about an hour, then it shuts off. It will occasionally come on and off after that, but I want to know what should I do to fix this? I have made sure it is in correctly, there is no smokiness in the bulb, and I cleaned the surface the part that the light touches to get power (these are the lights you just twist in and prongs from the light touch metal plates on the back of the dash where the heater controls are). Any suggestions?

 

The GEM Module is controlling all interior lights. Try cleaning the connector of this module using electric contact cleaner.

 

Wait, those are supposed to light up? Looks like I have a new project. Where is this GEM module? I suspect it may be why my compass/thermometer thing isn't working.

Maybe I'm wrong. This link shows the GEM Module behind the fuse box on a 97 f150 which is what you have Red....

It's beside the Brake Booster. You will see a lot of wiring on the corner. The harness is using a bolt as a lock. There is a water mark on the connector so it means water is dripping there, I'm not sure what seals is wearing out.

Remove the connector and spray some electric contact cleaner to remove the corrosion.
