REAR HEAT AND FRONT CONTROL PROBLEM

2003 GMC Yukon

Heater problem
2003 GMC Yukon V8 Two Wheel Drive Automatic 72000 miles

Hi, the heat in my Yukon is actiing funny. I am geting no heat to the rear unit and the front unit is producing heat. The front blower is acting weird. It will stop blowing, or blow at a certain speed. You can not turn it up or down. The control panel shows adjusting the fan speed but it does not effect the volume of air being pushed.
