Older vehicles used manual cables to open and close the doors, so I'd look in that area if you have manual controls, otherwise look into what is controlling the door to divert the incoming air supply source properly.

Sounds like you need a condensor and dryer replacement if your refrigerator is to high or low it will be warm air and turn compressor on and off I just replaced my compressor and i made the mistake of not getting a new condensor and it doesnr get as cold as i like and build pressure
