AC clutch works intermittently

[2002LibertyLimited]

My AC clutch works intermittently. It will work good and then I will go shut off the car and it won’t engage. Any help would be appreciated

Welcome to the forum.
I would start by checking the high and low pressures, using a set of AC gauges.
The compressor may not always engage if it is low on refrigerant or not with specifications.

Swap the AC relay with a similar one nearby but yeah you need to read the pressures as above.
