ac high pressure switch.


Recommended Posts

According to my DTNA Connect partsPro 6 diagrams, the switch that is on the receiver drier is the control switch to turn the fan on and off according to the pressures within the system.

The Hi/Lo switch to keep the compressor from engaging if either the pressures are too high or too low is near (about 8 " away) from the receiver drier on my truck, but being a cabover I am sure it is different than yours.


Click on the switch on the parts listing you are after, and that number will light up in red showing the position.
