Bi-Level Mode

When the operator selects Bi-Level, the following occurs:

• The mode actuator is in neutral position.
• The defrost actuator has vacuum applied to it through the Blue vacuum line.
• The defrost actuator closes the defrost door, thus opening the heater door though a mechanical linkage.
• Vacuum is bled off the mode actuator and the vent door is held stationary in the half open position.
• A/C is forced ON.
