So, get this. My right-front door lock wasn't working since last year. I bought the part from ECS but hadn't gotten around to swapping it yet.
Then, last week, I'm in the car on the way somewhere, glance out my right window and see...........my door lock button. In the UP position.
"Did I pull the door handle when I got in the car? I don't think I did..."
Pushed the door lock button a few times, and guess what? The damned thing works.
Completely on its own.
Now that's weird.
