Air Delivery Improper

Air Delivery Improper

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. Ensure that the cable loop connects to the crank pin, and that the cable sheath is retained.

If you do not discover the cause of the problem, disconnect the control cable at the crank pin and check the air control door travel and effort. If the door travel and effort is proper, check the control cable travel at the heater module end while moving the mode lever.

If the cable end doesn't move, check for the following conditions:

* A broken cable or control assembly part
* Unattached cable end at the control assembly
* A sharp kink in the control cable sheath that could cause unacceptable binding
