If it's not the switch, it might be where the wires go from the body to the door.  One might be broken.

I'll pop the door cover this weekend and take a look. I can easily bypass the console switch with direct 12V to the motor, see if that causes movement.

Did a power test on the motor last night....when the switch is activated up or down there is instant 12.5 volts going to the electric connector at the motor, and a slight mechanical TICK sound within the motor each time the switch is pushed. The motor looks like a real pain in the butt to remove/replace. Also looks like the lube grease on the tracks and rollers is original old 1982 lube...  Comments and suggestions would be appreciated.

Welcome to the family....we have many excellent "gear heads".  My 82CE has almost the same miles but I have never had a PW issue.  having said that, it may be time to take the door panels off and lubricate the PW glides - never gave it any thought until you mentioned it.

If the window is down and won't go up, check the spring that acts as an assist in raising the window. I had one break when I was driving and thought I'd been shot.  Window wouldn't go up. Replaced spring and worked normally.

If not the spring, I'd pull and disassemble the motor and check the brushes and lube the bearings.

I've had problems with my '82's windows and it was always the switch, put a new one in and it worked fine. Definitely bypass the switch and see how the motor runs, it could be the motor or like you said the hardware may be dirty and gummed up. Good luck, & welcome to C3VR.

Thanks all.  Hit the motor with direct battery power last night and no movement, just a short CLICK sound. New motor and gear is on the way and I'll swap it out. Still need to figure out how to get the glass up halfway prior to removing the old motor.

Have the new motor and gear on-hand now, but still can't remove the old motor because the window is full DOWN, meaning the glass and metal runner is right up against the motor, no way to get at the three mounting bolts. Any ideas on how to get the glass and hardware UP and out of the way?

SOMETIMES, a window motor that is giving up the ghost can be persuaded to move one last time with a few well placed love taps with a mallet, while holding the switch in the UP position(key on, of course). Assuming you already have the door panel off, tap(or beat, whichever you prefer) around the inner door panel right at the motor location with the window switch pressed. I've managed to get a few of them working just by slamming the door firmly while holding the switch on. Worth a shot.

Tried all that and then some. There has got to be a way to raise that window halfway up.

Got it done and new motor works fine. Had to remove the three long bolts on the electric connector-side.  That releases the motor housing assembly and get you up close and personal with the motor itself.  Turn the motor by hand to bring window up or down to align the infamous two holes, then put bolt and nut into those aligned holes. Remove the three mount bolts and replace motor assembly.  Took all of 30 minutes, maybe less.
