What is your question?
When the rear control for A/C and heat is turned in the heat temperature position there is a thumping noise that begins in the rear of the driver side. If I keep the temperature in the cool position the thumping stops. Any ideas what I need to do to fix?

Yes, the auxillary temperature blend door actuator (motor) has likely failed and needs replaced. It is the motor that toggles between cold and hot air. So, when you bring the temperature back to cold, the door doesn't try to turn anymore, and -- no clicking.
I have the same issue. Do you have instructions on how to change this? Pictures would be extremely helpful. Thanks
