Hey MPUMAS! The door came off easily, just as you described. The switch came out easily too. After that, the thing was like a Rubiks cube. I guess the switch pads are supposed to snap in place or remove easily, but I stopped prying at them when it seemed like they'd break, so wasn't able to look at the contacts. The rubber boot was intact, no obvious corrosion, so I went to Plan B. Replaced the motor/regulator with a used unit. That was the real problem. Not the switch. So, thanks again for the help.
