Anyone have know the part number or correct(GM)
name for this item. I'm having a hard time finding one
online. It's for a 2000 Blazer.

 

The Low Pressure cutoff switch is GM Part # 52473139 AC-Delco part # 155643. That's the switch on the compressor.

The high pressure cutoff switch is GM part # 89019183, AC-Delco part # 1550812. That's the one on the drier or the condenser.

 

Awesome, Thank you!
