Driver side works fine. Passenger side won't blow any heat, only cold air. A/ C compressor is running. Remove actuators & operated door manually. No change.

pull hvac fuse inside car for 60 seconds with key on then reinstall . it may reset actuators. if auto temp control where you set temperature then it must be scanned. I may need to be scanned anyhow if actuators are not working. compressor will run until below freezing.
