On my '46 half ton, there are two control knobs above the driver for the wiper (drive side only in my case). At times, if I pull and twist and move these knobs, the vacuum wipers will move. Exactly how are these knobs supposed to work? I referred to the owner's manual and service manual and found nothing. Are the knobs to be pulled? Turned? Is one 'on and off' and the other 'speed control'? Which one is which? Left? Right? Any help is greatly appreciated.
Also, any recommendations on a good 'replacement arm and blade' are appreciated as the ones I ordered (company name omitted) are very thin and leave a lot to be desired. Thanks!
