i just changed my unit on drivers side door man it was a pain well first it started off with not going at all i thought it was the motor but motor was good the wire was just getting hung up because the plastic piece broke on the track,so first disconnect motor from track and hit switch to see if it turns,and if not then replace motor,be careful not to loosen the cable.you almost need it exact tension for the track to work right.

most common issue is the belt got twisted. You have to remove the cover and keep the lock from engauging...

Mkisner, I have a 2003 gmc 1500 extend cab. I hear a small fan running in the headliner. It's very loud when cold outside. When I press on the grille in the head liner it quiets down. After the cab warms up the sound goes away. I ask the mechanic at the dealer what in heck is that. He said it's a fan that registers inside temperature for the air/heater. They have to take the headliner down to change it. He said expensive to change because of labor so I live with it. That is the explanation that was given to me. It does look like a speaker. The On-star voice receiver is in the mirror and speakers are the radio. That's why the radio music mutes when talking to On-Star or using the truck phone. You might what to know that Verizon has a deal with On-Star to add the truck phone to you Verizon bill for $9.95 per month sharing your minute with your cell phone. Verizon will assign a new phone number for your truck. It works great and you can program voice commands for the phone. Very powerful and clear. You can't go wrong but you have to keep On-Star active. Ken
