    Default Question for Paul regarding cooling fans.

    Have you ever heard that the operation of the cooling fans are also dictated by the AC pressure sensor ???...the AC pressure sensor controls the AC Clutch operation...more than 410 psi or less than 30 disengages the FSM and Mitchell SI doesn't mention this at all...trying to help a member on another Forum and someone chimed in on these AC pressure sensor values for fan turn on and off which he sees in HP Tuners...NEVER heard of ???...oh, and when the car is first started your AC fans will come on low speed if AC is this just a PCM "strategy" that is not written anywhere ??...THANKS !!
