I replaced the top and bottom door actuators on my ac/heater box because I had cold air on one side (driver ) and hot on the other then got on both and you could hear them trying to move but didn’t . So I replaced them. I still only had heat on one side and cold on the other (driver) I did the reset by setting it on auto and , took the fuse out etc. That caused me to have floor and defrost and nothing else. So I replaced the climate control unit . Same problem. Yesterday I was headed home . Air was blowing out defrost and floor But it was working. Stopped at the store . When I started the Tahoe back up all I had was heat . Anybody have any suggestions ? I am lost at this point
