My four front AC vents are not blowing air. Cold air is coming out from the two small upper front vents just not the main four. Also, cold air is coming out from the rear vents fine and air is coming out of the defrost vents fine when it is switched to that mode. I am reading it may be an AC door actuator problem? Can you confirm? Thanks!

Good afternoon.

Yes, it could be a mode door actuator. I will attach the procedure and a picture.
