You probably have automatic air conditioning with dual zone capability, Please review the owners manual for the dual zone operation. I looked in the service manual and certain heat / air settings criteria have to be met before the system will work properly in automatic mode. If those conditions are not met, the system will assume manual operation and mostly play dead waiting for the user defined manual settings. Start with a good review of the dual zone automatic settings.

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: the heater is only working on the passenger side

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.

A/c putting out cold air. on passenger side warm air on driver side. Had it recharged 2 weeks ago. What would cause this problem?


Check the heater motor actuator, in the inside in about the center under the dash attached to the heater duct. The actuator is a small motor that opens and closes the door on the air unit to direct the hot or cold air. One of the doors is not closing from the heat side of the unit.

Heater blows cold air on drivers side warm air on passenger side


I would say your heater core has clogged up, or the hoses leading to the heater core.

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

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.
