This is a very common problem with these trucks. I have seen this may times and it seams to be more common when it gets hot out side. Here are some directions on how to replace the actuator. It takes me about 10 minutes but I would guess it may take you around 1 hour. Its not too hard of a job.
First you must remove the door panel.

You have no other warrantys expect the 5yr/100k mile powertrain warranty. Your truck has only had one warranty repair, whick was a recall. You do have one open recall on the truck that should be done, its for the heated washers. You will remove this option due to a fire risk. They will also give you some money back because they have to remove this. Since you have low milage, it is likely GM will help you if you call the phone number I gave you. You will need to give them the VIN and mileage as well.
This is the warranty history.
