Problem: When the dash is apart and everything is dismounted and laying on the floor so we can observe what opens and closes when the control switch is moved, the duct doors appear to be in the wrong positiion relaive to the position of the switch. i.e. switch at Max A/C & normal - duct door appears to shift air to defrost vents instead of the dashborad vents.. Questions: Does anyone have the vacuum schematics for vacuum motor (a/c-heating) from switch to each vacuum motor & the color codes. Can we get a diagram of which duct doors should be open or closed relative to each position of the control switch.
