Many thanks to the original thread author and all others who contributed. The info and photos came in very handy yesterday for the removal of the driver's door window motor on my '93 Limited. Once I got that dimple hole drilled, it went quick and easy.
Weird thing though - once I removed the motor, I plugged it back into the electrics and tested it. It seemed to work just fine, running strong and smooth. So, I cleaned and lubed the regulator tracks and re-installed it. After several test cycles, it seemed to work perfectly.
The original symptom was that the window got stuck in the down position. When pressing the "up" button, you could hear a clicking sound in the door, but no apparent motor movement. After taking the interior panel off the door, I tested the connection between the "auto down module" and the motor with a multimeter and found the voltage to be normal, ruling out a bad switch or "auto down module". All wires and connections appeared to be in excellent condition.
So, perhaps the regulator joints and tracks just needed to be cleaned and lubed? Anyhow, many thanks to all for the info. I recently acquired this vehicle, and am sure I'll be using this forum rather often. This Explorer appears to have been cared for extremely well, and I love the way it drives - so I'll want to keep it running for a good long time!
