REVISION SUMMARY

In step 3 of the REPAIR PROCEDURE, the illustration showing the self-tapping screw was revised to reflect the proper screw.

SYMPTOM

There is a fluttering noise from behind the dashboard with the HVAC set to floor or defrost mode, the blower set to maximum, and the temperature set to maximum heat.

POSSIBLE CAUSE

Under certain HVAC settings, the defrost damper door linkage can flutter. This can be initially triggered by an external impact, such as driving over a pot hole or down a rough road.

CORRECTIVE ACTION

Install a self-tapping screw into the defrost damper door shaft in the heater case.

REPAIR PROCEDURE
