I only want to take this apart once if I can; the rear passenger window in my '82 coupe won't roll up or down and slides down a bit on its own; both the motor and switch are fine, that is, I get motor noise when using either the switch in the rear or the one in the console. Is it most likely a window regulator or guide? Or is the motor/regulator the same thing here? I've seen both referred to, so I'm not sure.

It is usually the regulator as I have a bad one in my 83CD and I took it all apart and found it was the regulator. The motor comes off the regulator. The motors are usually good. I replaced the regulators in both front doors and they work mint.

Guides are a pretty common failure and are far cheaper to replace than the regulator assembly. But you won't know until you can get to it and inspect.
