I can't figure out the controlls on my 66 to make the defogger go on its a non ac car.

Top slider all the way to the right, all three lower sliders all the way down. The one closest to the driver is heat (down is on), the middle is TEMP ( up is cooler, down is warmer), and the right one is DEFROST (up is off, down is on).

if it still doesn't work after all that..check your cables and see if they have popped out of the holders where they connect to the door levers
