    The prostar primary and secondary gauges point down to six o'clock and the beeping noise and low pressure lights will not go off. The truck does hold air though.

    check your air switch sensors probably that is the issue they should be mounted on the firewall.

    Yep sensor or wire problems. Sensors are located behind the cluster on the right hand side.

    I have a similar problem, but on mine the secondary air pressure gauge shows over pressure, drained tanks to empty and it shows sometimes +60 psi sometimes +30 psi on the secondary gauge, I switched the air switches around and nothing changed. Could it be the bcm?

    I have the same problem.. comes out once in a while... My buddy who works over at the International Dealer in Gary, IN said it's a common problem and the culprit is the high side pressure switch...( Somehow they are connected electrically) and I did notice my A/C stops working when the gauges are pointing down and beeping... What do you guys think? Doesn't make sense?? Dealer says High side pressure switch (3 wire above the A/C compressor on the AC line) is $165!!!!

    MEI/Airsource #1473. Any Truckpro/Compar/Fleetpride carries MEI or Airsource products. About $30. Maybe less.
