Question about 2008 Chevrolet Impala LT
Blows only warm air when driving , plus gurgling sound coming from passenger side . Only blows cold air when sitting at stop light
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.

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.

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.
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.
