Any suggestions where to start?

s a side not neither of my key fobs work, I have tried all the tips and trick and cannot get them to work. I am not sure if this is tied to it at all. I do have an aftermarket radio and have had a car audio place ensure it is all installed correctly so I am not messing anything up there.

Any help would be much appreciated.

The AC system has two "safety" switches that prevent power from being applied to the compressor clutch;, both are pressure switches, one for too high gas pressure, the second for too low gas pressure. Most likely, one of these is engaged. Start by running a system pressure test.
