You need to open the vent assembly and clean up your direction flap that controls the vent direction. Also the seals that block air may be broken and letting air in vents you don't want cool air into. You can replace the seals with insulation tape made for doors. the very thin tape. good luck

SOURCE: heat works on driver side, passenger side blows cold air.

Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

SOURCE: heat blows out driver vent when ac on

this problem is caused by a defective air temperature control blend door actuator motor, it is about center of dadsh in air ducting, it moves the door that diverts air for cold from ac or hot from heater, you must remove the dash to repace it, about a 15 hour job fotr a home mechanic with a factory repair manual, nearly imposs without one.

SOURCE: driver side heat blows cool air passenger side

Hello. The side that is not operating properly has a bad temp door actuator located up under the dash. I am assuming this vehicle has driver/passenger(dual)climate control heat and cold settings. This is a very common problem on these vehicles. Hope you find this information useful!

SOURCE: I have a 2005 GMC Yukon XL and my heater only

Your heater problem is more than likely a bad temp door motor.The seat heater problem is probably one of your elements.Either back or bottom.If your switch light is coming on then the element is bad.

SOURCE: cool air blows on passenger side and blows warm

I had the same issue on my 2005 Bonneville, and found that several other GM vehicles have the same problem. If you have Climate controls for driver and passenger, the first thought is that it is an actuator or actuator door problem.
But, it's most likely that you are low on freon. Your system only has about 2-2.5 lbs of freon. You may only need to add 0.5 lb to get cold air back on the driver side.
Of course, this means that you have a slow leak that will need to eventually get fixed. My leak is slow enough that I have to add 0.5 lbs each 4 weeks.

Got a1997 cadillac deville got heat on passengers side no heat on drivers side could you tell me the problem.no defrost on drivers side either help please


DTC B1340 Air Mix Door #1 Movement Problem !
The heater and A/C programmer supplies voltage to an internal motor that drives the air mix door. The heater and A/C programmer monitors the air mix door position feedback from a sensor on the motor. If the air mix door is requested to move but the feedback voltage does not change, the heater and A/C programmer will store DTC B1340. If the air mix door feedback indicates that the feedback is near the hot or the cold extreme, the DTC will not set. Evaluate the operation of the air mix door through self diagnostics as described in the test description.
Test Description
Perform the Diagnostic System Check before continuing with the diagnosis of this DTC.
A Scan Tool allows for the direct control of the air mix door by observing the following conditions:
• The air mix door position feedback value
• The value`s difference from the air mix door commanded position value
These readings indicate a fault internal to the heater and A/C programmer in the air mix door sensor feedback.

Did you perform the Diagnostic System Check?
--
Go to Step 2
Go to Diagnostic System Check
2
With the engine running, connect a Scan Tool .
Turn the dual zone to OFF (passenger temperature offset at 0 or OFF).
Exercise the suspect actuator using the temperature control on the control assembly.
Is the door being commanded (COM) to the proper high and low values?
COM High 100 %
COM Low 0 %
Go to Step 3
Go to Step 4

If you are unfamilier with this , i suggest you take it to a ASE certified repair shop or the dealer .

On my 2009 1500 silverado, the driver side air cond blows HOT air as if the heat is on, but if you cycle the driver side temp control up then back down several times or turn the truck off like short trips...


There is a damper that controls whether heat or cooling or somewhere between that is controlled by the temperature controls. A separate system is controlling the passenger side and the driver side heating and cooling. I hope this is still under warrantee. If not it might be a big job to diagnose whether the problem is in the heat and cool controller, the wiring or the damper device. I hope this helps.

Driver side heat blows cool air passenger side blows hot air. Both thermostats are on hot, recently had no heat flushed radiator and got half heat


Hello, this is cused by the drivers side temp door actuator. there are two electric motors that move the temp doors from cold to hot. there is one on the drivers side and one on the passenger side. you will need to replace the one for the drivers side.

  • Remove the left instrument panel (I/P) insulator.
  • Remove the knee bolster bracket bracket. Disconnect the electrical connector from the left air temperature actuator.
  • Remove the mounting screws from the left air temperature actuator.
  • Remove the left air temperature actuator.

    2005 Chevy Impala driver's side heat blows cold, but works on passenger side. Was told a vent is probably not opening to allow for the heat to get to the driver's side? Where can I locate this vent?


    First....buy a drivers side air flow actuator at a auto parts place for dual zone heating/cooling.
    (NAPA etc will have it.....or the dealer)
    Open the glove compartment.....all the way....you may have to take the screws out at the bottom......look in at the heater assembly....look over to the left....you will see the two air flow actuators.
    Look at the part you have and match it to the part on the heater assembly.
    The actuator that is closest to the engine is the drivers side control.
    Replace it.
    Try your controls and check for heat and cooling on both sides.
    The stepper motor in these actuators goes bad on quite a few...but over look that.....you have a great car,good for many miles of trouble free driving.

    Sounds like a problem with the "Drivers side temp actuator motor".
    Each side has a motor that controlls the temp. door inside the dash for the driver or passenger side. These motors are approx. $75, plus 1 hr. labor to install. See more info here...
