Some old timer said you don’t want to blast the defrost because that will heat it up and melt the snow. The water will then freeze over your entire window. He said to crack the driver and passenger windows and put the heat on the floor. That should keep the windshield cold and the snow won’t stick to it.
I can’t for the life of me get this to work and default blasting the defrost. Is this some sort of fuddlore or maybe it’s not cold enough yet?
