INSPECTION FLOW
SYSTEM DESCRIPTION
Component Parts
Intake door control system components are:
- Front air control
- Intake door motor
System Operation
The intake door control determines intake door position based on the position of the recirculation switch. When the front air control is set to DEFROST, or OFF, the front air control sets the intake door at the fresh position.
COMPONENT DESCRIPTION
Intake door motor
The intake door motor (1) is attached to the intake unit. It rotates so that air is drawn from inlets set by the front air control. Motor rotation is conveyed to a lever which activates the intake door. Door position is then fed back to the front air control by PBR built-in air mix door motor.
DIAGNOSTIC PROCEDURE
SYMPTOM: Intake door motor does not operate normally.
Perform diagnostic procedure for LAN system circuit. Refer to MTC-41, "LAN System Circuit". LAN System Circuit
