Drivers door lock/unlock switch

So apparently my master drivers door lock/unlock switch is going out....but before heading to junk yard....
Occasionally works...key fob unlocks every door BUT drivers door....occasionally passenger door will unlock it..... checked door wiring harness looks good..when manually moving it there's no resistance / clicking .... until it's rare working moment that comes and goes.
Window switches work fine on that same master switch..
Anything else before to check before grabbing replacement switch?

You can test that switch for function with a meter before you make a trip to the yard, and the wiring inside the weather boot you can see when the door is open is very prone to breaking check that first.

Also, make sure the setting in your OIC is set to unlock the driver door first. That could be a thing...

I know you said you checked your wiring harness and found no problems, but it really sounds like you have a broken wire in there. Mine exhibited a lot of the same symptoms. Have you removed the boot and looked for broken wires or did you just wiggle the boot and didn't feel anything out of the ordinary ... because it might feel solid but there are a bunch of wires in there and it only takes one.

The switch contacts can be tested with a continuity tester/DMMI so do this before making a parts run. IF you discover a problem, I think the interior of the switches can be sprayed with contact cleaner - that may help a bit. These switches are fairly beefy and I haven't seen/heard of them failing much at all.

I more strongly suspect a wire break in the wiring harness in the boot between the front door and frame. Move back the boot as far as you can and inspect each wire, even as it enters the door. This is a common and well known failure point on this model jeep.
Good luck

Upon further inspection it was a wire in the door jam bundle....fixed ...resolved...
Thanks for the persuasion to re-examine that....

EDIT / UPDATE: It was the thick guage ORANGE wire with white tracer going through it....

Did this also fix your interior lights and rear wiper?

HEADS UP....passed on wrong colors....did this at night....tired.....
The wire that was disconnected / reconnected that affected my master door lock was the ORANGE/ with white tracer stripe....large gauge....only other large gauge in bundle is black....

SORRY!

And yes...this was only affecting the master door lock...nothing else noted.

Think that is the main power wire. If you look at the picture I posted, you can actually see on my power wire a white mark at about the same spot where my ground wire broke, which is probably a fatigue indicator. Chances are I will be tearing mine back open to fix that when it also breaks.

Just want to say thanks for the info, my door lock was doing the same thing. Opened up the harness and sure enough, the orange/white wire was completely severed and the black one was looking almost as bad. A couple of snips, some wire crimps and electrical tape and everything is back as it should be.
