One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

    In AC mode, heat eventually comes out on drivers side. I had the actuator replaced by mechanic at a cost of $300.00 ($150 for the actuator and $150 for labor). New actuator worked fine for awhile now it's doing it again. Anyone have any suggestions or instructions on how to install new actuator?

    The vents facing the driver blow out hot air when the air conditioner is on. Sometimes it goes back to cold and there have been times when I have to pull over to restart the vehicle. I just turned the heat on, and now cold air comes out then heater is on. Is this a recall problem?

    2005 tahoe. have noticed rear a/c blowing hot if it is on at the same time or before front a/c. have to turn all a/c off, turn on front, then back and it usually works. sometimes have to restart the vehicle to get it to work. just replaced the battery and fusible link cable between battery and alternator, now the passenger side is blowing hot. since we're at the 39th day in a row of 100+ outside, i don't need the heater. i've read other blogs and it seems to be either a mode selector motor or actuator door issue, but i haven't seen anything definitive. can anyone help, please!

    Driver/passenger air vents blow hot then cold when using A/C. Back to cold when you restart the vehicle.

    AC blows hot. Have to turn off engine and turn back on and this seems to fix until next time.

    trying to get cold air thru the dash vents is a hit and miss deal. air will go thru the defrosters for the most part but in az. this takes a long time to get the inside cool. has electronic air front and rear .all air coming out is cold but just the wrong place

  • when air condition is on hot air blows on drivers side some of the time.. If I turn the vehicle off it will reset it. Same thing happens sometimes on passenger side.

    When the heat setting is on heat is only in the front the rear heat vents do not blow hot only cold even when the rear heat setting is on hot.
