Porsche cayenne S: no heat what so ever, just AC (cold air)

Customer Question

Porsche cayenne S:
no heat what so ever, just AC (cold air) all around.
I know that one of my actuator (under the glove box is bad) but even if I disconnect it and actuate by hand still cold air only. Where is the Heat to AC actuator or change over valve located?

Hello I'm Wolfgang. There is no change over control valve. First a scan test of the climate control system to see if there is any blend door faults. Was a scan performed? Is the coolant level full? Please let me know. Thanks
