Whenever it rains, for the next few days, my truck thinks my door is open. This causes my interior and bed light to stay on. Sometimes while I'm driving, my doors will lock and unlock constantly. I removed my door panel to find wet wiring. I'm not positive this is the problem, but it makes sense. The weather stripping had a few holes from breaking in with a coat hangers, so I sealed them with Flex Seal. That didn't help. My next guess is the water is riding the seal the houses the wiring harnesses located in the doors hinge. What should I do?

Have you tried moving the door around in the closed position to see if the light flickers with the key in the run position?

I tried that. Nothing happens. There's no play in the door. It's closed tightly.

Let me see if the door switches are part of the latch or a seperate switch. So we can jump the switches to see which one I ls causing the problem. Sotimes its a matter of the switch not being pushed all the way in when there seperate this can happen. Also have seen water get in them and cause issues when it rains like it sounds like could be happening in your case.

Do you need me to take the door panel off and take a picture of the door latch switch or are you going to look it up yourself?

Looks like you have seperate door jamb switches there located on the body of the truck that the door goes up against it when you close the door. They just pop out with some side retaining clips you just push in a little on each side of the switch. While rocking the switch forward. See if its got water in any of them also make sure your switches dont have any screws holding them in you never know.

I found the switch you're referring to. It may be the problem. I was playing with it, watching it change the notification on the dash and turn the interior light on and off. Then, it stopped working. I unclipped it and there's corrosion and rust. The rubber seal around it wasnt flush against the truck. Without it connected, my truck doesn't say the door is open, also doesn't know when it is open. I'm going to head to the store and see if they have any.

The bad news is, I can't get the part at any local stores or have it ordered in. I'm sure I can find it online somewhere though. The good news is, without the door jamb switch connected, my interior light stays off. For me, the light staying off is far less inconvenient than it staying on. Thank you for the help. You da man!
