So I have had an intermittent problem on driver's rear door latch (5/2015 build) where on pulling the interior or exterior handle, the door would not open 50% of the time - and then be stuck with window down until some time passed or the cable release was used. The window would fall but the latch would not release. I even started having trouble with the cable release not working or requiring extra effort. I greased the latch and nothing changed.
So I replaced the door latch. No change.
I replaced the door handle microswitch wiring harness - no change (and no visual issues with it).
My 2 remaining thoughts are door control module or wiring harness defect.
The door control module would be $300+ to change to a Gen 3 and the wiring harness defect I don't really want to know....
I really don't want to deal with Tesla for obvious reasons beyond financial. They could do the door handle by mobile so that is easy enough but is that $300 wasted?
Any thoughts or experience or any info on how these signals are sent?
The other thing that is weird is that a shutdown usually fixes it. I can't be sure but I just tested it again and it worked after the car went to sleep. It almost always works the next time I try but there is usually a drive so I figured it might move a bit. But even now - just sitting in garage, it worked after a shutdown. If it matters, I am on original MCU1 with 93k.
