Thanks. Obviously some situations are different.
Not understanding the problem initially, I lubricated the cables (Driver's side) along with everything else I could spray lubricant on. This helped for awhile but the motor stuck a couple of times after that. Each time I would take the panel off (was getting good at that by this time) and loosen the two small nuts on the motor to release it from its jammed position (could hear it release), and lubricate everything again. I nursed it along this way for a few Months but eventually gave way to replacing the regulator (includes cables and motor) and, knock on wood, no problems with that side since Summer 2005.
Probably best to replace the regulator assembly so everything is new. Seems the price for the regulator assembly has dropped somewhat, saw some on line the other day for less than $90.00 (includes the motor). Also saw some regulators without the motor - didn't know such a thing existed. Take a look:
Since the motor is weak, anything to help it out might work. My sense is that if the motor doesn't work right away, the switch triggers an overload protection, cutting off the power. During my experimentation I also hot wired the motor - and it worked. Conclusion is that if the power is left on the motor long enough, it will likely work. Boderline stuff for sure.
