CONDITION SUMMARY

NOTE: Airflow through the windshield demist vents is not affected by this concern.

SITUATION :

The customer may experience one or both of the following symptoms:

These symptoms may be experienced on the left or the right sides individually but also both sides at the same time.

CAUSE:

The airflow distribution doors have become locked. In some cases, the foam seals on the back of the distribution doors have become detached and trapped the doors.
