well first you should check under the hood to see if the compressor is engaging. it sounds like it is. asuming it is, i would suspect either low refridgerent, or a worn out compressor.

how can i tell if its engaging, i do think its low on refridgerent because the compressor use to be cold and now it gets as hot as the motor, is there a way to test it?
