    Hello,

    I am having a problem with the application air pressure gauge on my instrument cluster where it stays at 30psi and doesn't change after truck starts moving. Performed a cluster self test and everything checks out fine the gauge moves around. Has anyone ever had this happened to them? maybe its a bad solenoid or sensor in the truck? I have attached a picture of the instrument cluster.

    Does the needle move if you pull trailer brake lever all the way down? Should do up to like 100.

    Don't pull trailer brake lever all the way down while rolling cause it will lock the trailer brakes up
