Air Door Cable: Adjustments

Function and/or temperature control cables self-adjust when levers are moved to extreme right of WARM and/or DEFROST slot in face of control assembly. On models equipped with a control knob, the cables self-adjust when the knob is rapidly rotated clockwise toward the WARM position. Some function and temperature control levers move from top to bottom.
The control cable wire should be pre-set to prevent kinking before attempting self-adjusting procedure. Cable pre-set may be performed in vehicle or before installing a replacement cable assembly. Proceed as follows to pre-set cable before installing assembly:
