I was getting into my truck one evening and I noticed that my interior light went out not thinking much about it i started the truck up and tried to roll down the window, no go. The next day all was well. It has happened on and off but it just added something weird. If the engine is off the interior lights will come on but just a sec or 2 after i turn on the engine I hear the relay under the dash click off. and then no lights. If I turn the engine off again all is ok. Anyone have any ideas?

 

Check your fuses and interior lamps relay.
I would replace both of the relays in the top left corner under your dash.

 

GEM MOdule has gotten water in it at some point in time.

 

Ive had some odd electric issues to, driver window won't roll down when in drive, and my power locks won't unlock but they lock fine...
