Not sure if you are wanting to do this yourself or not. We do offer a free AC check so you can come by our shop and we will be happy to help you. If wanting to do it yourself, not sure what tools you have. First is a visual inspection to see if you have a loose belt on your compressor, anything blocking the compressor from working and to check the refrigerant levels in your system. If your pressure is normal but the air is hot, you MAY have a compressor problem. Checking to see if the compressor clutch is engaging is a simple visual inspection. The compressor is usually located towards the front of your engine, just inside the grill of your car. Your car should be running with the AC on to check the compressor clutch. The compressor looks like a small motor with a large wheel on the end. The wheel (which is the compressor clutch should be spinning.) If it is not spinning, you have a problem with your compressor. Could be electrical or mechanical. Go this far and let us know your results.
