I think my door switch is sticking. When I start the truck, I have a "Door Ajar" light on, on the instrument panel, and the dome lights won't go off. Just like if the door was open. Really hard driving at night with all the lights on inside the truck. They eventually go off, but you have to wait a while. Where's the door switch? Do I have to remove some panel to find it? Thanks.

 

Its inside the latch assy. To change it you have to take off the door panel and then remove the latch. You can try to spray some WD-40 on it - that works usually for a little bit - just a temporary fix. Needs a new one to fix it for good.
