RE: AC Compressor doesn't engage
I assume & clutch cuts-in & A/C works when temperatures are below 90 F. If this is so, your compressor & clutch are OK.
At high ambient temperatures (mid 90F), does the A/C work when you start up initally & cuts out after running a while.
If so,I think that the high condensing pressure switch attached to the receiver/drier, is activated, causing the clutch to cut-out.
