A/C blows cold on driver side but hot everywhere else

Good morning,

Can you give me the high and low side readings of the Freon pressures while the engine is running and the A/C is on? I need to see those numbers to be sure the system is working correctly.

I attached the location of the blend door actuator.

When you command heat and cool, put your hand on the actuator and see if you can feel it move.

You could also try the calibration procedure that I posted below.

Actuator Re-calibration

When replacing the HVAC control module it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC control module be sure to perform the following:

Important: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.

1. Place the ignition switch to the OFF position.
2. Disconnect the scan tool.
3. Install the HVAC control module.
4. Connect all previously disconnected components.
5. Start the vehicle.
6. Wait 40 seconds for the HVAC control module to self-calibrate.
7. Verify that no DTCs have set as current DTCs.

When replacing the HVAC actuator it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC actuator be sure to perform one of the following:

Important: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.

Preferred Method (w/ Scan Tool)
1. Clear all DTCs.
2. Place the ignition switch in the OFF position.
3. Install the HVAC actuator.
4. Connect all previously disconnected components.
5. Start the vehicle.
6. With the scan tool, initiate the Motor Re-calibration feature of the Heating and Air Conditioning Special Functions menu.
7. Verify that no DTCs have set as current DTCs.

Alternate Method (w/o Scan Tool)
1. Clear all DTCs.
2. Place the ignition switch to the OFF position.
3. Install the HVAC actuator.
4. Connect all previously disconnected components.
5. Remove the HVAC/ECAS fuse for a minimum of 10 seconds.
6. Install the HVAC/ECAS fuse.
7. Start the vehicle.
8. Wait 40 seconds for the HVAC control module to self-calibrate.
9. Verify that no DTCs have set as current DTCs.

The first picture is with the engine running. The low is good the high is high. Spray some water on the condenser and see if the air cools down and the high side drops.

The second picture is a problem. The low side and the high side are not the same indicating a expansion valve that is closed and needs to be replaced.

The first video shows the system cycling because the low side drops to 20 pounds or less. The high side is low indicating possible low in Freon.

The third picture should not have the compressor running. If it does, you may have a bad compressor.

The second video has good pressures.
