I have no heat flow or ac flow through the dash vents, only in defrost and feet. Could this be a selector actuator issue?
I was designated to drive a group of friends to the club one cold night. Prior to picking them up and getting to the club, the heat was doing very well. Then once we were taking off afterwards, the heat obly flowed through the defrost and floor vents. With leather seats those girls were not happy in the back seat.
