Have Truck Repair Questions? Ask an Expert
Hi Gill Jason. Its Dan. What is the chassis model and engine model of this truck? Be sure all your fuses and relays check out okay and the pressure switches for the high an low side are good as well as the wiring harness and connector pins. If they are okay, verify the system has a full charge or the clutch will not engage. Let me know the chassis and engine info if we need to dig deeper into this. I have to go out on the road for the afternoon/evening but will reply back on my next login. Let me know
HiCustomer Did you get this resolved?
