The air conditioning does not work. Blower works heat works. Pump won’t kick in when I turn on for air conditioning.

There is a fuse called the HTR-AC fuse. The best way to figure this out is to jump power to the compressor to see if the compressor comes on.

If it does then we need to check the pressures on the high and low side. Here is a guide that will help with this:

Below are the wiring diagrams and a chart that will help with figuring out what the pressure may indicate.

Let me know what questions you have. Thanks
