Update form early Jan13:
Dealer received new part (assuming motivator) for driverside rear window and they replaced it (under warranty still).
Engine running, so no "weak battery" issues...
It does rise up a little faster now, but the front windows beat it easily in a race.
Tried just running it by itself to see if it would be faster, but upward speed did not change.
I guess it is what it is...
