I just found this thread... and glad I did! I thought I was going crazy thinking my driver side window was slower than the rest! Now I know I'm not crazy... at least not fully crazy! LOL! Looks like I get to go have a chat w/ service one of these days to get a window channel "lubed" up!Went to the dealer today, they lubed the channels but reported one was not correctly aligned from the factory. Happy to report they all run the same speed now!
