Hi all.....on the heater controls for my 63 4x4 sub there is only one button left on the fan speed leaver which is the first closest to the driver. There are 3 more without buttons. Can you tell me which do what from the left to the right please.
Still hoping to hear from someone who has done a conversion to power steering on a 60 to 66 4x4 sub.

Will post pics
