You can jumper(bypass) a pressure switch but risk burning out compressor if fluid is too low, or blow out a hose if pressure is too high
WOT = wide open throttle
WOT relay is 5 pin, so when its off it passes 12v to compressor clutch if AC is turned on in the cab
If you press the gas pedal to the floor, so wide open throttle, the computer turns on WOT relay which cuts the 12v going to compressor clutch, shutting AC off, so engine can make best power for passing or ???
When foot comes off the gas pedal AC comes back on
Thanks Ron,
So jumping the 2 wires @ the pressure switch won't bypass the WOT relay & it will operate as it should.
Also, & I may have missed this, but if the A/C system was left on since the last time driving the truck,
the compressor will not engage right away while starting the truck the next time, correct ?
Thank you Sir !
