Air control switch on 2000 Jeep Grand Cherokee Limited 4.7l

If the air flow cannot be controlled from vent/defrost/floor you may have a blend door issue. This is an electric motor that operates a door in the heating system to control airflow. There are usually 3 motors controlling airflow direction,heat and recirculation. The Ac not blowing cold may also be another problem. If the AC is operational, the compressor will be engaged and the Ac low pressure line under the hood will bw cold. If this is all ok then a blend door issue should be suspected

You will have to check the flap operating controls behind the centre consol as anything could be wrong from a vacumn pipe to a operating mechanism ,even the computer controlling the climatic control .

THE ELECTRIC ACTUATOR MOTOR NOT WORKING. NOT ALLOWING AIR DOOR TO OPEN SO THE AC AIR CAN CIRCULATE THROUGH THE VENTS.

most likely there is a door in the dash somewhere that controls the flow of the air. the actuator that controls the door for that side might be bad

sounds like the clutch field on or bearing on the front of the compressor went bad take a closer look at the pulley on the comp. and see if there is any debris or melted plastic coming out behind the pulley,if so the clutch,field and bearing should be replaced,hope this helps

May be I can help,you have a vent door actuator motor that has gone [email protected]

make sure nobs are not broke pull them off check for cracks if not the your blend door might be sticking

There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

My 1999 limited does this. When i bought it off the guy he said that its because of some flap down by the passengers left foot. In mine the passenger air barely even blows because of this.

Could be the switch or the resistor.
