I took the door apart, disconnected the window from the regulator, pushed it up and removed the regulator so I could play with it. I can hear it engage to go down when I push the switch, but not to go up. I tried the switch from the right side and got the same result. As a last resort, I ran wire straight from the battery to the leads between the switch and the regulator. Voila, smooth quiet running both up and down.
So, I think the problem is in the wiring, especially since it has the same behavior with both switches. Any ideas on how to trace this or where to start? What's the best wiring diagram source?

... electric windows and eventually found it to be one of the 2-N-1 control switches on the console. I even drilled holes in the side allowing me to spray cleaner and then WD-40 through the switch... but to no avial. Some of these switches can actually be taken apart, cleaned, and reassembled... but it you strike out with cleaning/repair, you should be able to shop and find these for ~$40 each in an after-market brank. My switches were cracked so it make it an easy decision so I think I replaced both switches on the console and one of the single switches on a back door... all three for ~$100.00!
They all now now work flawlessly... and the child-proof center button on the driver's side of the console also disabbles both rear window switches.
