Hello All,

Feels great to be officially on this forum. Been reading it for months. Finally ran into a problem I just can't Google or figure out.

AC stopped working. Selected Max AC; electric fan turns on (at start up), interior blower sets to high, AC light turns on. But nothing but hot air. Used INPA to see if I could learn anything. Noted that I was receiving a high Pressure Sensor Value of !11.6 (!= I assume is an attension getter that it is not within normal....right?) Found only 1 pressure sensor, on the passenger side, between the engine and the strut tower. Replaced it. Of course bleed the AC system out. Had the system evacuated and recharged. They ( the auto shop) couldn't get the AC to work. Tested for voltage going to the AC compressor, reading 0 volts. Plugged in INPA again and found the pressure sensor switch has a value of !37.....what the heck.

Question: Are there 2 AC pressure switches or just the 1? And if there are 2, where are they?

Thank you for any help....
