Hello and welcome to JustAnswer!

There are a handful of things that could be preventing the compressor from engaging ranging from low charge, the compressor relay, wiring or the integrated power module, the control head, evaporator temperature sensor, pressure transducer, or an incorrect ambient temperature signal.

The first step in diagnosing the problem will be to either check for fault codes or check system charge. Has either been done?
