Six problems related to power window have been reported for the 1999 GMC Sierra. The most recently reported issues are listed below.
: the contact stated there were two problems with the vehicle. First, the fuel gauge worked intermittently, but the vehicle has not been inspected by the service dealer concerning this issue. There were no warning indicators prior to the intermittent failure of the fuel gauge. Second, the passenger window dropped into the door without warning. The vehicle was inspected by the contact and it was discovered a cable was broken that held the window in place. A shim was added to keep the window in stationary position.
Tailgate straps break for no reason. I have replaced them twice with in the past 4 years.
Passenger side window fails to operate. This was caused by a faulty motor which is a common problem.
#1. Rt. Window intermittent. Satisfied with repair #2. Abs sys. Lite on. Abs sys. Inop. Cost was to be $1200, but after neogations repaired under warranty. (vehicle was over 36 mo. Warranty. ) I feel this type failure is too premature @ 26,00 mi.
Power driver window failed in down position. Tailgate cable frayed, ready to break. Abs deploy when brakes applied and bump hit on dry road resulting in loss of breaking power. This vehicle is the worst vehicle I have ever owned and I've had a lot of them.
Power switches and motors failed.
