RE: Engine Fan
I'm with Rawze on this one, as it was my first thought too, having been through this myself... I would suspect that AC high pressure sensor, not the sensor itself, but the wiring to it. Pull the split loom back on that wire harness from the sensor back, they tend to break from engine vibration over time or rub the jacket off the wires. Simple thing to check...

If the wiring is OK, and you have a PACCAR product, like Snail said, the flaky cab/body controller could be the issue. In a ProStar, it is located behind the kick panel on the driver side. No clue on other brands.


User's Signature: 2008 ProStar, OEM 600hp CM-871, 18spd, 3:42, in framed in Rawze's driveway. Every day is a fresh new episode of, "The Twilight Zone"... Rod Serling lives rent free in my head. I can smell the Chesterfields.
