Improper Air Delivery

IMPROPER AIR DELIVERY

If the "Functional Test" or other diagnosis indicates improper air delivery or a failure to shift modes when the mode lever is moved, check the attachment of the affected control cable at the heater module Be. sure the cable loop is connected to the crank pin and the cable sheath is retained.

If the cause of the problem is not discovered, disconnect the control cable at the crank pin and check the air control valve travel and effort. If there is proper valve travel and effort, check the control cable travel at the heater module end while moving the mode lever. If the cable end doesn't move, check for a broken cable or control assembly part and for an unattached cable end at the control assembly. Also, check for a sharp kink in the control cable sheath that could cause severe binding.
