Door Open Issue

[WorkmanLtX]

Hey everyone, hopefully posting this in the right place. I have a 2018 Ram 1500 Laramie Eco Diesel Crew Cab. 77K miles.

Yesterday the truck started saying my driver side door is open and it isn't open at all. I wiggled the wires that are behind the rubber boot in the door jamb area and it quit for an hour or 2 then started doing it again. My interior lights stay on and if I can't auto start the truck or move it around the farm without my seat belt on. I would greatly greatly appreciate some help, thank you!!

How is this useful to the OP?
Maybe provide him a diagram of the wiring for the door sensor

If you wiggled wires and then it worked you might have a loose connection.
is the latch moving in and out fine? Maybe it's getting stuck open?
I read for 4th gens the switch is in the door latch area, maybe try spraying some silicone lubricant spray in there.

Same thing happened to my 2010 ford f150. Aways said door ajar. I could wiggle the wires in the rubber boot between the door and the jam and make it go away. The fix was to pull the rubber boot back and cut the wire loom open, solder and shrink wrap the broken wire. Rewrap the loom with tape and use small zip ties on each end of electrical tape to prevent unwrapping.
There was a nylon stiffener in the boot, but opening the door over time caused a wire to rub and eventually break. This is a easy fix if all the other suggestions don't work.
