Mix-Blend Mode

When the operator selects Mix-Blend, the following occurs:

• The mode actuator has vacuum applied to it through the Brown vacuum line, pushing the vent door closed.
• Vacuum is bled off the defrost actuator, holding the defrost door stationary in the half-open position. The heater door is also held stationary in the half-open position through mechanical linkage.
• A/C is forced ON.
