Component

Description

1.

IPDM E/R

Refer to

PCS-7, "RELAY CONTROL SYSTEM : System Description"

.

2.

ECM

The ECM sends a compressor ON request to the IPDM E/R based on the status of engine op-
eration and load as well as refrigerant pressure information. If all the conditions are met for A/C
operation, the ECM transmits the compressor ON request to the IPDM E/R.

3.

A/C Compressor

Vaporized refrigerant is drawn into the A/C compressor from the evaporator, where it is com-
pressed to a high pressure, high temperature vapor. The hot, compressed vapor is then dis-
charged to the condenser.

4.

Refrigerant pressure sensor

Refer to

EC-28, "Refrigerant Pressure Sensor"

Component

Description

1.

Front blower relay

The front blower relay controls the flow of current to fuse 17 and 27 in the Fuse Block (J/B).
The relay is grounded when the ignition switch is in the ON position.

2.

BCM

The BCM receives the fan ON and A/C ON signals from the front air control and sends a com-
pressor ON request to the ECM.

3.

Front air control

The front air control controls the operation of the A/C and heating system based on inputs from
the temperature control knob, the mode switches, the blower control dial, the intake sensor,
and inputs received from the ECM across the CAN. Diagnosis of the front air control can be
performed using the CONSULT. There is no self-diagnostic feature available.

4.

Variable blower control

The variable blower control controls the speed of the blower motor by controlling the ground
circuit of the blower motor. The front air control provides voltage to the gate of the variable
blower control based on the position of the blower control dial.

5.

Intake door motor

The intake door motor controls the position of the intake door. Fresh air is allowed to enter the
cabin in one position, and recirculated inside air is allowed to enter in the other position. The
intake door motor receives position commands from the front air control.

6.

Intake sensor

The intake sensor measures the temperature of the front evaporator fins. The sensor uses a
thermistor which is sensitive to the change in temperature. The electrical resistance of the
thermistor decreases as temperature increases.

7.

Air mix door motor

The air mix door controls the mix of hot or cold air that enters the ventilation system. It is con-
trolled by the front air control based on the position of the temperature dial. The air mix door
motor LH receives position commands from the front air control.

8.

Mode door motor

The mode door controls the direction the conditioned air passes through the ventilation sys-
tem. Through a series of levers and gears, the mode door controls the defrost door, the foot
door, and the vent door. There are 5 preset positions: VENT, B/L, FOOT, D/F, and DEF. The
mode door motor receives position commands from the front air control.

9.

Front blower motor

The blower motor varies the speed at which the air flows through the ventilation system.

No.
