Slow /binding Window - 2008 Xterra

For the second time the X has gone to the shop on warranty for the drivers side window. It slows at the bottom when going down and has trouble closing until have way up. This is worse in cold weather. dealer seize the motor is fine and lube the tracks and it works again. I think its the regulator. Suggestions anyone?

Yes, it is likely a regulator problem. If you keep after them about it and keep all of the documentation for your visits this should keep it under warranty even after the warranty period officially passes.

I once had a similar issue and it took 3 visits and me getting really p.o.'ed at the dealer’s service dept before they agreed to just replace the dumb thing.
