Recall - A/C Controller Replacement: Overview

No: SR-10-003

DATE: November, 2010

MODEL: 2006-08 Endeavor

SUBJECT:
HVAC CONTROLLER REPLACEMENT - SAFETY RECALL CAMPAIGN

PURPOSE

The HVAC (heater) controller may intermittently send incorrect signals to the HVAC mode door until the various input data to the controller stabilize. These incorrect signals may cause the heater case mode door to infrequently move to unselected settings when the heater is operated. Additionally over time this excessive door movement may damage the mode door shaft and cause the door to stick at one setting location. These conditions could affect defroster performance resulting in delayed clearing of the windshield.

Dealers are instructed to replace the HVAC (heater) controller assembly with a new improved part programmed with updated software. Dealers should also inspect the mode door shaft. If the mode door shaft is cracked repair it as described in this bulletin procedure.

AFFECTED VEHICLES
Certain 2006-2008 Endeavors built between 5/16/2006 and 1/28/2008 equipped with manual air conditioning.





IMPORTANT

CUSTOMER NOTIFICATION

A letter will be sent to all owners of affected vehicles telling them to bring their vehicle to their Mitsubishi Motors dealer for HVAC controller replacement. Owners in Canada and cold weather states will receive this notification the 2nd week of December 2010. Owners in other areas will receive this notification at a later date. Dealers are instructed to perform this repair for any owner of an affected vehicle who requests the repair (if the campaign has not yet been completed) regardless of whether they received a notification letter.

A copy of the customer notification letter is shown in this bulletin.

REQUIRED OPERATIONS

1. Before starting this procedure CHECK ON THE WARRANTY SUPERSCREEN to verify that the vehicle is an affected VIN for this campaign and that this campaign procedure has not already been completed.

2. Disconnect the vehicle battery.





3. Replace the heater controller assembly with the new improved part listed in the PARTS INFORMATION section of this bulletin. Refer to GROUP 55A in the appropriate service manual for heater controller assembly replacement details.





4. Disconnect and remove the mode selection motor. Refer to GROUP 55A in the appropriate service manual.





5. Inspect the mode door shaft for cracks.

If the shaft is NOT cracked, reinstall the mode selection motor and reconnect the battery. This repair is complete.





If the shaft is cracked:

a. Use the hose clamp provided in the Heater Controller repair kit.





b. Install the hose clamp with the slot positioned on the shaft as shown for ease of tightening.

C. Position the clamp 3mm away from the outer edge of the shaft, so it will not contact the case when the shaft rotates during motor operation.

d. Reinstall and reconnect the mode selection motor. To ensure proper operation, align the flat side of the motor shaft with the flat side of the mode door shaft.





e. Tighten the clamp firmly to the shaft.

f. Reconnect the battery.

g. Turn on the fan and confirm proper mode door operation by using the mode selection dial to move through all door positions.
