When A/C is turned on the engine's temp. rises close to over heating and it blows hot air.
This is Chevrolet Cavalier 2000 4 doors 4 cyl.

Is the cooling fan at the radiator coming on with the A/C and running strong?

There's your problem. You need to trying jumping power and ground directly to the motor to see if the motor itself is bad or not.

Don't even wait. You have a bad fan motor. Just replace it before it causes serious problems.

Motor can be tested with jumper wire or may be NG. Other is relays, fuses and temp sensors or plain poor connections.
Hammer would know better that I if it controlled by ECU of the car. Test fuses with a light. Relays are harder but frequently respond if you know you have the right one with a whack! Replace it even if that works! Don't let the car overheat if at all possible - never mind the A/C it will really hurt it with hard overheats!

Yup - if I missed that it means an eye check up is moving up on the list of to do's! So true - when a bumped electric motor suddenly works for a while it's time to replace it as Hammer said,
