Started out earlier this week with the truck thinking the driver's door was always open and the window switches in the driver's door not working. I pulled the door panel off, checked all the connections but I didn't find anything obviously wrong. Now that I have put it all back together, the truck thinks the door is always closed and the window switches in the driver's door still don't work. The radio does not turn off and the dome lights do not come on when the driver's door is open. The locks and mirrors work as they should. Any ideas where to start or what to test?
