Hi Folks, hoping you can help me. The power windows on my truck only work when the key is turned back to accessory. The dome light never works, and the courtesy lights (the ones on the switch) only work when the key is turned back to accessory. Do you think it is the GEM Module, ACC relay, or?

Thanks!

 

What year and cab size?
Different year trucks were wired differently.

 

It could be the ignition switch block.

 

I was just going to mention that they sometimes have lower switch problems. The OP is getting power thru the GEM, but only on the accessory side, so the switch is the common denominator here. I'd check it, and it is easier to access than the GEM imo.
