Try pulling HVAC fuse inside car for sixty seconds with key on it then reinstall it may reset the actuator. Otherwise the actuator could be bad. Here is a guide to help walk you through the steps and the location of the right side actuator.

If so the only actuator to worry about is the passenger side blend door actuator.

Heres a guide to check out on replacing a blend door actuator. Not vehicle specific, but it will give you an idea of what to do

(1) HVAC Module
(2) Mode Actuator
(3) Air Temperature Actuator (C67), Air Temperature Actuator - Right (CJ3)
(4) Recirculation Actuator
(5) Blower Motor
(6) Blower Motor Control Processor
(7) Air Temperature Actuator - Left (CJ3)

See the diagram below for the locations

Hello,

I have a 2000 Chevy Impala with 76,000 miles. It has the 3.4 L engine (the non-SS model). The AC blows nice and cold on the passenger side, but no cold air blows from the driver side. It does not have dual climate control. Any ideas on what to look for?

Thanks!

I had the same problem and my car was under warranty they replace the the whole a/c panel. The actuators were sticking bad ac controllers.

The car has a dual heating switch. I replaced the heater control module thinking it was that but it was blowing air just not getting warm on the drivers side.

With dual climate control, you have two blend air doors. They are designed to control the amount of heat or cold air entering the vehicle. It sounds like one is stuck. Both are located near the heater core HVAC box. Check to see if they are both working (opening and closing).

My car blows cold air on the drivers side and hot air on the passenger side when the heater is selected.

More than likely, you have a fault with a temperature actuator. The one that deviates from requested, would be the one suspected. There would be a fault code in the system, that would confirm this. Try this actuator recal procedure and see if it restores normal operation, this may be temporary.
Actuator Recalibration
Calibration Procedure
Use the following steps to perform the calibration update:

Turn OFF the ignition.
Remove the battery positive voltage circuit fuse of the HVAC Control Module.
Important: The module memory will not clear if the battery positive voltage circuit fuse is installed in less than 60 seconds.

Wait 60 seconds.
Install the fuse.
Wait 60 seconds before moving the HVAC controls.

The fuse that powers the HVAC module, is the DIC/RKE fuse in the RH junction block, behind the right side instrument panel access panel. I am not sure what the collateral may be for removing this fuse, since it has the letters RKE in the heading. It may lose the remote keyless entry programming.

Sounds like you have a bad temp actuator for the drivers side. You can remove it and check and make sure the blend door isnt binding
