I have a 2008 Chevrolet Impala and the heater blows cool air on the passenger side. Any recommendations?

Driver side seems to heat up fine, passenger side is cold, both temperature controls are set to heat.

SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

SOURCE: 2004 chevy tahoe, dual climate control, blowing different temps

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

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!

Do you have separate drivers side and passenger heat controls?
If you do have this system,the common problem is the control unit s on the heater/a/c assembly. Can you adjust heat and cooling on one side?
Then the other side control unit is most likely bad.

2008 impala only gets warm air blowing when driving ,also can hear bubbling from passenger side near firewall


It could be your heater core or check your over flow tank for the radiator to see if it is your antifreeze is up to the line marked on the side of tank and check the over flow hose, make sure the clamps are tight.

Air conditioner works fine on both sides but heater only works on passenger side. cool air on driver side. I've disconnected battery for 10 min. and reconnected battery, then running car for about 1 min....


Hello and welcome. this is caused by a bad temp door actuator for the drivers side temp door. it is stuck on cold. the temp door actuator will need to be replaced to repair this concern. here is a picture. it is mounted to the drivers side of heater a/c case, behinde the dash.

2008 Impala heat problems


remove the radiator cap and let the car run for 30 minutes to let the air out of the heater coil, these radiator caps on the 2008 Impala will not bleed off, while running notice if air bubbles air slowly rising to the top of the radiator cap, re-install cap and see if this fixes problem, we also purchased a new radiator cap, this fixed my wifes car.

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.

The heater is only working on the passenger side in my 2005 impala. the driver side is blowing cold air. please help


Do you have dual zone heat and cooling controls?
If so......the drivers side air flow control unit on the heater assembly is not working.
It is mounted on the heater assembly and can usually be accessed through the glove compartment to change it.
The stepper motor on these units fails often.
This should be the problem on your car 99%...if you have a separate heat/cooling control for driver and passenger areas.
