This could be the blend door or it may just be low on Freon. We should check and make sure the compressor is coming on, and if it is then we need to check the pressures with a gauge set.

Here is a guide that explains this and how to evacuate and recharge the system. I also attached what the pressures should be based on ambient temperatures. Let us know what you find. Thanks
