Thanks!
I'll have to read the tutorial on how to reply. Think I screwed it up.
In any event, based on what I read tonight, I'm going to do the following:
1. Spray "PB Blaster" into the switch after I disconnect it from the control panel.
2. Take apart the switch and strech the springs; also spray "PB Blaster" on it.
If that doesn't work, I'll take apart the door per your instructions and get my neighbor who sold me the car to help me figure out if it's the motor (which it doesn't appear to be) or the regulator (whatever that is?!).
Appreciate your help.
