The air conditioning seems to turn itself on and off. on 2000 Chevrolet Malibu

I had the face plate replaced. Now the air only comes on when I have the fan switch on #4, but even then after a while it turns off and I have to turn it back on.

May be the blower motor resistor is going bad and needs replaced.
