Power window troubles

Didnt find anything relevant in a search...!
Symptoms: Intermittent movement of drivers window going up. Down seems to be OK. The window doesnt seem to have trouble moving like it needs lube.
Popped the switch plate out first and the drivers side seems to be OK. Passenger side is suspect.
There is 12v at all three terminals of the driver side switch. No voltage at the passenger side
When the window stops and the switch is activated for the drivers side I can hear a relay buzz and click under the dash near the steering column.
Knowing GM products, this is probably a very common problem, and someone out there can point me in the right direction without spending LOTS of time testing.
