MODE CONTROL CAM ALIGNMENT

Alignment Procedure

NOTE: The HVAC module must be removed to accurately set the mode cam gear timing. Failure to do so may result in poor HVAC performance, and damage to the HVAC module.

  1. Remove the heater and air conditioning evaporator and blower module assembly (HVAC). Refer to Heater and Air Conditioning Evaporator and Blower Module Removal and Installation .
  2. Remove the mode control cam. Refer to Mode Control Cam Replacement (C67) , Mode Control Cam Replacement (C60) .
  3. Inspect the mode valve levers and internal vent valve operation prior to installing the new mode control cam assembly.
  4. Replace the components affecting the proper operation of the vent valves.

NOTE: If the heater cam and mode cam are not aligned correctly, the mode operation will not function properly.

  1. Rotate the heater cam (1) counter clockwise, position the larger heater cam female tooth gear as indicated by the arrow.
  2. Install the mode cam (2) aligning the larger male tooth with the heater cam (1) larger female tooth indicated by the arrows, while aligning the channels on the back side of the mode cam (2) with the defroster valve lever pin (3), and the vent valve lever pin (4). The pins should be visible through the inspection windows.
  3. Verify that the large male tooth on the mode control cam (2) is aligned with the large female tooth on the heater cam (1).
  4. Re-install the heater and air conditioning evaporator and blower module assembly (HVAC). Refer to Heater and Air Conditioning Evaporator and Blower Module Removal and Installation .
  5. Verify for proper operation of the HVAC system.
