So about your vehicle, what testing at the door switches have you done?
It does sound like the drivers door. Can you remove the cover on the fuse block on the left end of the dash, in there is a connector, usually 12 pins for the door. Unplug that and see if the issue goes away. If no then I would agree the BCM or wiring around there. If so then wiring issues inside the door or boot with wiring to the door.The BCM is under the steering column under the trim. It is a programmed module so its not a simple remove and replace,
Ok, sounds good.
OK, I am not at my toolbox and I don't have my computer running. When I do return to my toolbox, I will look up the schematics again and get back to you.
Sorry, today turned insane, looking now.
That is not the BCM. It has 3 connector. Check the diagram posted.
The wiring you reported back on does not match the Body Control Module (BCM) though, thats my concern.
On the surface it does sound exactly like a failing BCM.
OK that was for the drivers door, I did want you to double check for chaffed wiring around the Body Control Module (BCM). Try a tap test, which is tapping sharply on the housing of the BCM. Check each connector for corrosion or water intrusion (possible leaking windshield, and I have seen a couple), and if that changes nothing and on corrosion found then I would try a BCM.
