AC not working. I have used the AC Pro kit on other vehicles with no issues. Hook up to this car (low press port) and the pressure indication immediately goes into the red. The compressor is engaged. Blower is working, it is just blowing warm air.

Hello,

It sounds like the compressor is bad not compressing the refrigerant. To find out for sure you will need a gauge set so you can connect to the high side port.

Here is a guide that will show you how to check.

Please run this test and get back to us we are interested to see what it is.
