Looking for information on the heater control door positions for a 59 F100. I get no defroster air at all. Looking at the position of the heater deflector doors in the defrost position it looks as if the air is directed to the floor. Since there are two cables that operate the defroster setting, where can I find information on which way the doors are supposed to be for the heat and defroster setting and which cable goes to which door?

 

Don't need the info now, took the heater housing off and found the cables were switched. Corrected the problem. Thanks for looking.
