Theory of Operation
The A/C Heater Control drives the Blend Door Actuator via the (C61) Blend Door Driver circuit and the (C34) Com-
mon Door Driver circuit. All of the door actuators share the (C34) Common Door Driver circuit. Inside the A/C Heater
Control, each door actuator has its own unique driver, but all share a single common door driver circuit. Due to the
shared circuitry similar DTCs can set at the same time for multiple actuators depending upon the type of short, its
location, and the direction the actuator is moving when the short is present.
When Monitored:
When the Actuator DTC Detection Test is executed.
Set Condition:
If the (C61) Blend Door Driver circuit is shorted to voltage.
Possible Causes
(C61) BLEND DOOR DRIVER CIRCUIT SHORTED TO VOLTAGE
