prostar blower motor quit

One other thing you may want to try is to reset your cab controller. I have mine on a dash switch specifically for the AC, as it is buggy as hell. You can reset it by pulling the fuse with the motor running. Give it a minute and plug it back in. That may solve your problem too... Or, with the motor off, disconnect the battery cables, so that there is no power getting to the cab. Give it a minute and reattach. That solves some other cab/body controller issues that I have ran into... Buggy ass trucks, there is an engineer at Navistar that needs to be in the stockade.
