What codes is the dash throwing? I had same problem turned out to be a bad sensor. Read the codes i might be able to help you.

Mine happened to be on all the time as well, solenoid was ok but computer wasnt sending signal to solenoid. Well what i did was i disconnected the fan solenoid wire + & - that feeds computer and bought me an on/off switch connected to + from battery then to + on solenoid and ground from solenoid to switch then to ground on chassis, now that way i can turn the fann off and on whenever i want but you have to be careful with engine temperature. If you re careful that will fix your problem and would be a 4.99$ easy fix instead of hundreds maybe thousands of dollars chasing the issue. Hope it helps you.

Hi guys i have a 2006 cxn613 vision. My problem is the fan will stay on all the time even if i press the on/off switch it will stay on, the dash shows fault code 4-2 and 10-4 im trying to figure out where the fan solenoid is. It is air operated not electrical, and yes the air line is flowing plenty of psi. Any help?

So I need some opinions and advice on my mack vision. Its got AC 380hp engine 10 speed maxitorque transmission 711,0000 miles on it Is 380 hp enough for hauling sand on end dump trailer? Im trying to find the torque range but I dont know how to find it. How reliable is this kind of truck? With 711,000 miles on it; what can I expect? Engine sounds smooth and smooth transmission as well. Only one owner.
