A/C Doesnt Work
So my A/C was ice cold yesterday and boom nothing today. so i vaccumed it and it had 1.60lb 134a in it. put back the refrigerant and still nothing. the clutch wont engage. clutch moves by hand. the one wire doesnt have no voltage going to the compressor. the 30amp breaker under the dash is good. what do u think my problem is?

To state the obvious:
The pressure switch only cuts off power to the compressor if it thinks you are to low on Freon. If you pressure tested your system and confirmed it's full, short the two connections to the switch and see if the compressor kicks in. If it does, you've indeed solved your problem.

the picture you showed is not the refrigerant pressure switch, that is the coolant thermoswitch for cold idle assist.
the refrigerant pressure sensor is under the plastic duct to the inboard side of the passenger headlight in the engine bay. disconnect it and jumper the connector, if the clutch kicks in then you either have a bad connection at the connector or a faulty pressure switch.
edit: oops, actually read the thread.
