Ok so tonight i was going to trouble shoot my A/C system. When i go to checking the thermostat I found out that the one i have is not the stock prelude A/C thermostat. It looks to be a Civic styled thermostat with 3p connector instead of a 2p. Could this be the issue? It has power and the thermostat itself has continuity. Im stumped atm so a little help would be awsome.

 

After a quick reinspection i found the pressure switch to be bad, glad i double checked. I am still baffled by the thermostat tho. Also what would cause the air to not be cold if there are no leaks and the clutch is kicking in after jumping the pressure switch?
