Click when defrost active - no A/C no dehumidify
 

A/C inop, blows hot. Clicks every 30-ish seconds when any A/C functions engaged. System does not de-humidify which is the biggest problem. This has got to have been covered ad naseum on this site but my searches of this forum using keywords I think should work return zero results. I have no gauges so don't know pressure. What has this commonly been? I can't be the first person to see this in a 2002.

Tried to keep it short, thanks.
