Door ajar - disable?
Hey all, my excursion engine had a failure so I picked up an expedition for transportation while I locate a replacement engine.
It has the door ajar issue, and I sprayed all the switches with penetrant and it didn’t fix it. I suspected the passenger front door as it wouldn’t ding when I opened and closed it like the drivers side. Apparently this was an issue in the past because that switch was unplugged and the connector had a jumper in it.
Its still showing ajar, so I started working my way around the doors, rear hatch (main hatch not glass) was unplugged as well. I plugged it back in and still getting error.
Anyways instead of replacing a bunch of stuff and spending $500 I am wondering if there is a way to just disable the door ajar warning all together? The fob won’t work and the doors don’t auto lock because it is getting the error.
Id love to just be able to use the fob to lock and unlock the doors if possible.

Short answer: NO
Sit in the driver's seat. All doors closed. Cycle the key on and off with the radio on. The radio should stayed powered for 10 minutes with the key off. While the radio is ON ( key OFF ), open the front doors one at a time to see if the radio turns OFF when the door is opened. If the radio does not turn off after opening the door, that door's "door jamb" switch is bad and should be replaced. You can find any of the door jamb switches on Rock Auto. If the radio turns off immediately after you turn off the ignition key even with all doors closed then one ( or both ) front door switches are bad. It's fairly common. People lube the door latches with oil and that oil gums up the switch because the switch is located on the bottom of the latch and all that crap runs down into the switch. The rear hatch switch doesn't turn off the radio but it does send a "Liftgate Ajar" message to the message center. Some owners don't want to spend any money repairing their vehicles, so they try jumper wires and various other BS that seldom works.

I’ve done all that stuff, I know for sure passenger door is bad. I tried jumping the connector and that didn’t do a thing. I have an excursion with the same switches and even connected a working switch to see if that helped and nothing.
I checked the wiring harness on the passenger door and didn’t see any bad wires in there either.
Is there a way to use a multimeter on these connectors and see and see if the harness might be bad where it connects to the switch?

Which Expedition is it? Need the year and trim level to make any specific advises on that. Best would be a pinout and diagram on the connectors, then you can check if the wiring is good. In "worst case" you could jump the wires at the vehicle security module so it shows as permanently closed if all you want is a quick and dirty fix for now.

I'm not sure if i got a connection to work or what happened when I have been messing with this, but I got my USB OBD and added the PID's for door ajar to ForScan and took a look. As I suspected the passenger side was the only one with an issue. I made a new jumper and gave it a try and it frickin worked! So I hooked up the old switch I cleaned up and that worked too now. Must have been a loose connection somewhere but shes all good to go now and the FOB works too!

A common fault (in general, not specific to Expedition) is that the wiring harness between the door and body breaks from fatigue after many years of opening and closing the door. That would be the first place I would inspect if there was a break or intermittent connection in that circuit. I believe there is a connector on the body side inside the kick panel somewhere, so a pinout of that should enable you to check continuity to the door latch. Let us know if the fault comes back, and I'll dig out some connector pinouts and diagrams for you.
