2007 Frieghtliner Columbia fuses

Did you check where the wires go into the door? There is a rubber boot you can take off. Sometimes wires break in there from opening and closing the door.

 

Open the door. In the door jamb is that rubber boot where the wires go from behind the dash to inside the door.

Now not trying to be mean here but if you don't see a broken wire then this job is beyond your know how. Every vehicle ever made with an electronic in the door has that rubber boot there. Your previous post shows yoh have an extremely limited knowledge and knowhow to trouble shoot this problem. Chances are you are going to just cost yourself more money than if you take it to a competent shop.

 

you could try switching out the switches, if you open the vent window in the rain water just runs right down the panel to those switches so they short out quite often. If that doesn't do it, take it to a shop. It will be cheaper and faster.
