I have a weird problem with my AC on driver side, once AC is on it blows cold air and stays cold for a while then all of a sudden it will start to blow hot air for a while and then back to cold and thats only on the driver side, while the passenger stays cold and doesnt change.

Checked the HVAC codes for any codes and all it shows 0 Codes.

Its a dual climate control and the screen doesnt work.

Pull fuse 37 on the passenger side, wait a few minutes, reinstall. Report back.

Done that and kept it for an hour and reinstalled it back, still the same.
Also got under the dash on the driver side to see the actuators, and yes they are functioning.

I'm out of ideas since you say the passenger side stays cold lol.

Low on freon?

Got it checked as well

Compressor would cycle of low or overcharged. I'll ask this. What have your air temps been like where you live. My ac is damn near useless in 110+ heat once my condensor is heat soaked in stop and go traffic. Maybe that is causing your compressor to cycle?

Over here it's like 110+, I never had any issue with my AC before and cleaned the condensor and radiator just Incase, but again it's only the driver side while the passenger side is cold.

This drove me nuts ..I had the right amount of Freon ... So I Took fuse panel cover off the Passenger Floor ... Kept car running with A/C on pulled fuse 27 and replugged it in and it reset the Damper/Actuary ..... WORKS PERFECT

It sounds like the problem lives in your air blend door which reheats the cold air coming off the evaporator. If you want to trouble shoot, find the heater inlet hose and clamp it off. With no coolant flow to the heater core, the air cannot be reheated. If the blend door is misbehaving, you should feel some change in airflow but it will no longer cycle from cold to hot because the air diverted to the heater core will no longer be heated.

Good advice guys but, i think he got frustrated and left the forum back in 2016 sold the car or he fixed it and went bye bye.
