Have you checked your liftgate fuse? In my 2006 Yukon, when the liftgate fuse went out the rear ac wouldn't work nor would the electric locks for the liftgate itself.
According to the 07 Refrigerant Oil Specifications an 99 GMC Yukon uses either 36 or 64 oz of refrigerant depending if the vehicle has rear ac. You can find more helpfull information about your vehicle ac system at www.idqusa.com.

The ac belt has a tensioner that is accessed from below, and takes a tensioner tool to loosen. Remove the serpentine belt, release tension on the ac belt then the belt can come off for replacement.
