Your a/c compressor is seized up. Get a professional to attempt to turn the outside hub of the compressor. If it doesn't turn, yoyr compressor is seized.
Thank you!! So does this affect the heater to? Been afraid to even turn it on.
Yes, in defrost or mix mode, the compressor engages to keep the humidity out of your car. If you unplug the cycling swith, usually located on the side of the a/c accumulator (most easiest place to unplug or the compressor itself) you can continue to use your heating system but when it comes winter time you may need to carry a roll of paper towels to wipe your windshield.
