Hello I will help you with your question, Have you pulled the blower motor? You should and see if you have debris in the blower cage or a mat of hair etc on the face of the AC evaporator coil. A flashlight and mirror are helpful to inspect the evaporator while the blower is out. Let me know how I can help Thank you

OK, the cage may have debris and it will restrict flow or any hair, fuzz etc on the evaporator will do the same. Let me know how I can help Thank you
