    Worked fine at night and in the morning it was blowing warm air or low to no air? Does the compressor sound to be running? Or just the blower fans?How long does it coolwhen you say it cools than stops cooloing? Are you on shore power or generator?-Ned

I got a 94 chevy cavalier. it was blowing heat just fine last night but when i went to start it this morning i noticed it wasn't blowing. its been cold and vary snowy the last couple of days if that helps.


if the fan is blowing and you have no heat and the car runs at the normal temp range then it would be your heater core needs to be replaced,if you have heat and its not blowing it would be the blower motor needs to be replaced ,or the switch is faulty.

Air worked fine all last night and his morning.


if the air comes on for a short time and then turns off for 15-30 minutes, the overload protection inside the compressor is shutting down to protect the compressor. this can be caused by blocked supply or return vents, improper charge, bad valves in the compressor, and a multitude of other things. the problem will have to be corrected first.

Auxilliary heat just started blowing cold air


SOund like you heating element has a open limit or the sequencer is bad. Another thing that it may be is the element wire has broken. Either way it sounds like you need a technician to come out and repair.

We left the freezer door open all night by accident two days ago


I turned the fridge side off on mine, and left it overnight (last night!). This morning there is frozen stuff in the freezer. I think the compressor motor just needed ALOT of time to cool down b4 it would work properly again
