Got tired of waiting for digikey to ship my back-order micro switches. Also the issue got worse so that 2 out of 3 times the door fails to open.
So I pulled the panel off and the handle module out. No obviously broken wires so I figured it had to be the micro switch.
Long story short, it wasn't the micro switch. It was indeed the shorter white wire that most commonly breaks. What happened is the strands all broke right before going into the insulator in the back of the switch but the insulation of the wire was still in tact which is why it wasn't obvious. This is the main reason why it was intermittent. The insulation was holding the broken strands on each side together so they were mostly making contact but sometimes failing.
It would have gotten worse and worse over time.
I soldered a new wire onto the switch itself after removing the micro switch wire insulator protecting the solder points. I then joined the new wire to the white wire (paired back about an inch) with solder and then shrink tubed over that. I did the re-route using the black tar stuff to hold the wire in place. I left the black wire alone. We'll see if it holds but for now the door is back to 100%.
I covered the back of the micro switch with more of that tar goop but that was after taking this photo:
