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.

SOURCE: 2004 chevrolet suburban AC blows hot/cold at same time

You need to replace the drivers side temp actuator that is located on the left side of the HVAC box. It is retained by 3 screws and is fairly easy to replace.

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.

SOURCE: 2005 Chevy Impala driver's side heat blows cold.

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.

My 2010 F150 Lariat. The heater blows warm air on driver side but blows cold air on passenger side. What could be the problem?


Does it have dual zone climate? If so, you have to adjust the passenger side. If it still doesn't work, check for vacuum hose off in engine compartment, going into the firewall.

Air conditioner


Check whether the warm air isn't going in with the cold air .Coolant line that runs into the firewall on the passenger side of the engine which is toward the bottom half of the firewall on the passenger side. If there is warm air going into the vents with the cold air then it blows warm air. You may have to shut it manually because it gets stuck sometime. Check it out.
