Two speed fan clutch

[redbeard]

I’m not getting this. My Fan just spins just enough to not raise dust and keep the a/c condenser from spiking pressure and kick the fan in on direct and cause a dust storm.
Being a California truck cold weather is pretty much a none issue.
With just an air activated clutch, using manual over ride before arriving to avoid the dust storm is a thing of the past.
Maybe I’m just lucky
