Hi, workin on a 76 factory v8 with factory ac. ( monza) The previous owner hacked the wiring harness to "fix" a blower motor control issue. I have the wiring diagram and can understand most of it . I do have a few questions. Notes referring to V-8 HR or V-8 HM models ? I know the fan runes at full speed at max ac and to use the fan control switch for all other settings . Dose the fan shut off completely when the ac/ heat selector (top lever) is in the OFF position ? I am trying to trace the wires to see what was cut/unhooked and what mite have been the original problem. I need to know what it is supposed to do before I can figure out what it is not doing. I have the factory manual, but it is not clear on the sequence of events. As always thanks in advance for your help .
