Hello All - The drivers window went down as called for but will not raise. I've bench tested the window motor and it performs smoothly in both directions. The other three windows operate perfectly. The four switch cluster has been removed and examined. Both the express and incremental raise/lower features of the drivers window switch seem to also be normal.

There is plenty of info on the net about the older C5's window regulator difficulties but not so much about the newer door design in the C6.

Dealer visits are always a last resort action for me so any assistance would be greatly appreciated - Thank you.
