Duel climate control acting up

change climate control the only way

1. Low freon. A mechanic once told me that the car will act like this when it needs a freon recharge. Such did not solve my problem, however. 2. Stuck door. There is supposedly a "door" (for want of a better term) inside the heating/cooling system that regulates temperature and/or cabin airflow. The door opens and closes according to the temperature and and dual climate settings selected. If this door gets stuck, it causes hot to blow out drivers side and cool on the passenger side. I am suspicious of this theory. Why would hot air correctly blow out of both sides? I had another mechanic tell me this one. 3. temperature sensor improperly reset. I read online that if the battery gets disconnected and reconnected improperly, it will cause a malfunction in the sensor responible for delivering the proper temp through the a/c system. The solutions posted were disconnect the battery and reconnect with negative terminal first; check all fuses that reference climate control, a/c , heater, etc in manual, remove for 15 seconds, reinsert or replace if necessary. This did nothing for me. However, I personally associate this intermittent problem with a battery reset. My wife's car has electrical problems (don't get me started) which necessitate frequent battery replacement. Everytime the battery has been disconnected, the problem starts again. 4. Computer malfunction. I also read that the problem may stem from the climate control interface itself (i.e. the thing with all of the temperature knobs and buttons). Replacing this is supposed to fix the problem. I have not tried this, and frankly, I refuse to do so. The only current solution I have ever found is patience. The problem seems to simply disappear after a while (albeit a long while). My wife and I both have Intrigues (Gasp!). They both have the same problem(s). Nothing works for either. Good luck. If you have success post your results.

There is a actuator motor that controls this,and it is not working,unfortunately ,the whole dash has to be removed to replace the actuator motor.If this was at all helpful,please rate,thank you.

If you have duel climate control, it sounds like the blend doors inside the heater box have broke. It is a rather large repair to do. If you don't have duel climate control, look for a broken, leaking or aged vacuum line under the battery try. Hope this helps.

Best of luck

If you touched any of the A/C controls within 45 seconds of starting your Suburban (after the battery change), you messed up the 'calibration mode' of the HVAC.

Pull the HVAC fuse (10amp) under the hood, and pull the two adjacent fuses (30 and 10amp) under the dash listed as 'climate control' in the manual.

Push the fuses back in, restart your car, but DONT TOUCH ANY of the A/C controls for 90 seconds.

I bet the A/C starts working again normally.

yur air handler could be bad on that side or if you have dual climate control the control for that side could be bad.

are you not getting any air or hot air???
Here is a laundry list from my memory as to what may be causing causing the problem.
1. Low freon:car will act like this when it needs a freon recharge. Such did not solve my problem, however.
2. Stuck door. There is supposedly a "door" (for want of a better term) inside the heating/cooling system that regulates temperature and/or cabin airflow. The door opens and closes according to the temperature and and dual climate settings selected. If this door gets stuck, it causes hot to blow out drivers side and cool on the passenger side.
3. temperature sensor improperly reset. if the battery gets disconnected and reconnected improperly, it will cause a malfunction in the sensor responible for delivering the proper temp through the a/c system. Disconnect the battery and reconnect with negative terminal first; check all fuses that reference climate control, a/c , heater, etc in manual, remove for 15 seconds, reinsert or replace if necessary.
4. Computer malfunction. The problem may stem from the climate control interface itself (i.e. the thing with all of the temperature knobs and buttons). Replacing this is supposed to fix the problem.

BEFORE TRYING ANY PROCEDURE PLEASE CHECK THE RESPECTIVE PART

disconnect the battery and try again to re sync the two sides, this is a common problem on all dual climate GM cars, if you can't get them to resync then you will need to replace the climate control head..

The actuator has gone bad. They can be programed, and reset, but usaly they are bad, and that will only patch the problem for a while.

you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.
