Our truck is a 2013 a DD15 the engine fan runs constantly it all seems to run normal…
When he shuts truck off the fan locks up as it should then he’ll engage switch with just key on the hub is able to spin freely by hand soon as he fires it up it’ll lock on again and blow constant, unplugged the wire connector from solenoid fan clutch engages. I pulled off the air hose going to fan he engages and air comes out… I plug it in, it locks up! Not sure what it is!
Just a FYI, the trucks gauges have had a problem for a long while one side of dash gauges work then the other half doesn’t. The side that doesn’t eventually works then the side that use to work doesn’t.
