The AC on my Cadillac STS only blows cold air on the passenger side. The driver side is still blowing hot. I recently added some new freon. >? Temperature sensor ?
I think more freon fixed the problem. Its blowing ice cold now. I just hope there isnt a leak

The temperature blend door on the driver's side might be broken or stuck. Also, if this vehicle does not have the correct amount of refrigerant, it will do what you are describing.

Does the vehicle have dual zone climate control, where the driver side and passenger side have different control? Sounds like a blend door issue on the driver side. Why did you replace the passenger side, was it blowing hot too when AC was on?
Check the actuator motor on the heater it directs the air into the vents. There is probably two of them be sure to check both. The motor makes the vents move and again directs the air where you want. Hope this helps.
It sounds like you have "zone" climate control. With "zone" climate control you can adjust the driver, passenger and sometimes other "zones" to different temperatures for the comfort of all passengers. Make sure that the Driver side is set to a cool temperature. If it is then you more than likely have a problem with the temperature controller for the driver side.
Blend doors control flow between hot and cold airflow . In a dual system both sides have their own separate blend doors . Possible bad switch, connection or wiring that need checking out .
My 02 Century has dual temp controls . One for driver for passenger. Make sure you don't have the dual climate enabled and just set for heat on your side and AC on the passengers
I had the same problem but it was blowing hot air on the passenger side of the car. I assume you have the dual zone controls that I have as well. The problem is most likely the damper that controls the flow of hot and cold air into the car. The motorized component of the damper is most likely not working and its stuck in the hot air position.
I had mine replaced by a repair shop so I cant tell you how to replace it but it may be something that you can do if you have the time and patience to work on it.
I would assume with multiple people having the same problems, there should be a service bulletin on this issue. may want to call dealer with vin # to verify. sounds like a heater control issue under the dash. something i would leave to the experts for repair
