Sometimes my A/C and heat works and sometimes it doesn't, but when it doesn't I still hear the motor working. When it does work the air blows out really good but when it doesn't nothing out of the vents?

Hi,

The air flow direction is controlled by a mode control cam actuator. If it is failing, you will lose control of the air flow direction.

I attached a pic of what I am referring below. However, the pic is for manual A/C. I need to know if you have a manual climate control or automatic.

Let me know.

Hi,

Here are the directions for replacing the part. However, before purchasing one, remove the old one and confirm it isn't working.

The actual directions are in pic 2.
