I am generally a VW bus guy. I recently traded a 1960 bus for a 1976 FJ 40 to take up in the hills rockhounding. Now there is no heat in a VW bus. I can’t figure out how to turn the heat off in my Cruiser. I’ve tried all the switched on the dash and the lever in all positions on the heater. It’s over 100 degrees in my neck of the woods today!
