LINCOLN:

ISSUE
Some 2009-2010 Expedition and Navigator vehicles may exhibit a noise coming from the dash area after vehicle is started or when the customer requests a Heating Ventilation Air Conditioning (HVAC) temperature change.

ACTION
Follow the service procedure to correct the condition.

SERVICE PROCEDURE

Test both driver and passenger side temperature blend door actuators on dual zone HVAC systems.

1. Start the vehicle and set the heater control to full heat. Repeat for full cool setting.

a. If a clicking noise is not heard at either end of the travel, do not continue with this procedure.

b. If a clicking noise is heard at either end of the travel, proceed to Step 2.

2. Replace the temperature blend door actuator with revise parts. Refer to the Workshop Manual, Section 412-01.

NOTE
THE IGNITION KEY MUST BE OFF WHEN REPLACING THE ACTUATOR. ENERGIZING THE ACTUATOR BEFORE INSTALLATION ON THE HVAC CASE WILL CAUSE THE PART TO BECOME MISS POSITIONED AND CORRECT ORIENTATION WILL BE LOST. INCORRECT ACTUATOR OPERATION MAY RESULT.
