Mode Valve Assembly

The film valve system has several operating characteristics:

• The cycle time for a mode change will vary based on the starting point of the film valve relative to the requested mode position.
• The maximum time to achieve a mode change occur when the film valve travels between vent and defrost.
• Mode change times may very slightly based on variations in system airflow, temperature and voltage.
• The amount of air rush noise heard when a mode change is requested that causes the film valve to move through three or more primary modes is dependent on blower speed.
• Recalibration will typically occur when the engine is OFF. The actuator noise heard during recalibration may be more noticeable than during normal operation.
