Started the trk but the fan no longer comes on while the tanks build air (it did a few days ago) Does that mean that my fan clutch is bad or ecm is toast?
easy way to check - shut engine off, take serpentine belt off disconnect air line to clutch. Spin the fan if it spinning free the clutch is place to look. Sometime clutch seized and few hummer smacks can fix it.

Sorry, hummer smacks?
