Low Side Pressure Switch
Does anyone have a pic or can anyone tell me which sensor this is? I have a '93, and I thought it's the one closest to the evaporator housing. Is that correct? I'm hearing now that GM revised the sensor and my current 2 wire setup now has 3...
Anyone have a definite answer as to which sensor it is? Anyone have any part numbers?
Thanks in advance.

15-5705 (AC Delco) (94-96)
The low and high pressure switch is combined in the three wire AC Pressure sensor in the high side line (small diameter) slightly forward of the evaporator.
PN 22599559 or AC Delco 15-72104 (92 & 93) or 22601618
15-20310 (AC Delco)(94-96)
Note that either one can cut off the compressor if pressure is too low.
