The problem I have is that i only have air coming from the floor heater. The rear vents and floor work fine. When i change from hot to cold the temperature works also, just no change from heater to A/C or defrost. Looking for any help.
Thanks.

Hi and thanks for using 2carpros.com.

Based on your description, the mode door actuator isn't working. That is the component that directs air flow.

The actuator is located under the dash and is part of the HVAC system. I attached the directions for replacement as well as a picture of the components for you.

Let me know if this helps or if you have other questions. Also, these directions are relevant for both manual and automatic temperature control.

Take care,
Joe
