    Hi guys,

    I own Cadillac cts 2005,

    My issue is that:

    When I turn the ac, air is blowing only from the defrost vents,

    what can cause the issue?

    Sounds like the mode actuator went out

    does it called the blend door actuator?
    because, I looked online and I saw that part control the temps, but all my temps are working fine, and cold and heat, just blowing at the defrost.

    Did you lose power at all before this started happening?

    there are a few actuators, one is for temp, the other is for which vents it comes out of. so you do have one bad.

    In another thread someone said that it's the same actuator, and I know for sure that the temps actuator located under the dash of the driver side.
    Do you know where the actuator that controls the vents located?
