Review on 💨 ACDelco GM Original Equipment 15-51343 Air Conditioning Refrigerant Pressure Sensor: Reliable and Precise Monitoring for Optimum Cooling Performance by Tarus Clinton

The new switch is on the left and the old switch is on the right. This was the perfect replacement for the high pressure switch on my 2007 GMC Sierra, it bolted right into its new home and works great. Little did I know there was a Schrader valve under that switch that allows you to change it without wasting freon. I decided to change this as I was rebuilding much of my AC system on a pickup truck. I have cold air again 🙂
