Was such a perfect fit, I nearly had it installed before the truck pulled away from delivering. Thank you.

Used this adjustable pressure switch on my 91 Sierra A/C system that has been retrofit to R134a refrigerant. Used it to lower the cut out pressure from around 26psi from the factory set one to around 22psi to get a lil cooler temps and it worked great. Screwed right on where the factory pressure switch was, only had to re-wire the electrical connector, but I used crimp on female spade connectors so I could adjust the switch while it’s in use.

Couldn’t stop my AC compressor from cycling every 3 seconds. Replace the switch and now it is cycling normally. This switch works perfectly.

If you suspect this part is out on your GM you can "By-pass" it by unplugging the wires that lead to this part and making a jumper wire to complete the circuit. If your A/C now works with this jumper wire, this is the part you need. DONT leave the jumper wire there. Your A/C's pressure could climb too high and literally explode under too high pressure. This switch protects your car. Cheap Insurance. BUY IT!
