DeVille DHS V8-4.6L VIN Y (2000)
Control Assembly: Description and Operation
Air Delivery/Temperature Control Circuit
The air delivery is controlled by the mode actuator which is mounted on the left side of the HVAC module. This actuator is controlled by the Instrument
Panel Module (IPM). The IPM adjusts the mode actuator to discharge the air delivery as requested by the operator of the vehicle. The mode actuator
sends a feedback voltage to the IPM. This feedback voltage is used by the IPM to determine which air delivery mode the system is currently operating in.
