97 ford f 250HD. 7.3 5 speed Needing to find location of all the places under the dash for the heater control cables, etc. Using the dash controls on the dash wont let me change from heat to vent or to the defrosters, floor, etc. Does anyone have a diagram of where the flaps, linkages are physically located. Due to someones homemade "console" everything in front of my shifter is hidden or covered. Are the "flaps" vacuum controlled or are the cable actuated?
