: the contact stated on two separate occasions the power windows failed to power up. Upon inspection the dealership determined the regulator assembly failed. The cables frayed due to rubbing against the slider mechanism. The driver side door was replaced. Updated 6/23/2006 -.
My passenger side window rolls down very slowly. I was told that all 1999 gm trucks and up with power windows have the same problem.
Front passenger seat belt retractor is locking up while driving. Dealer notified. The driver side window makes noise when rolling down due to regulator assembly failure, also the center console would not open.
Drivers side power window does not adjust sufficently to eliminate blind spot, mirror replaced under warranty. New mirror worked the same. Dealer says that is the way they all are. I am average size. This would be worse with tall drivers.
