Recirculation Control Motor Test

Recirculation Control Motor
Replacement

RECIRCULATION CONTROL MOTOR

1. Disconnect the 5P connector from the recirculation

control motor.

Incorrectly applying power and ground to
the recirculation control motor will damage it.
Follow the instructions carefully.

2. Connect battery power to the No. 5 terminal of the

recirculation control motor, and ground the No. 1
or No. 2 terminal; the recirculation control motor
should run smoothly. To avoid damaging the
recirculation control motor, do not reverse power
and ground. Disconnect the No. 1 or No. 2 terminal
from ground; the recirculation control motor
should stop at Fresh (when the No. 1 terminal is
disconnected) or Recirculate (when the No. 2
terminal is disconnected). Don’t cycle the
recirculation control motor for a long time.

3. If the recirculation control motor did not run in step

2, remove it, then check the recirculation control
linkage and doors for smooth movement.

• If the linkage and doors move smoothly, replace

the recirculation control motor.

• If the linkage or doors stick or bind, repair them

as needed.

1. Open the glove box. Remove the glove box stop on

each side, then let the glove box hang down
(see page 20-67).

2. Disconnect the 5P connector (A) from the

recirculation control motor (B). Remove the self-
tapping screws and the recirculation control motor
from the blower unit.

3. Install the motor in the reverse order of removal.

Make sure the pin on the motor is properly
engaged with the linkage. After installation, make
sure the motor runs smoothly.

Climate Control

Power Transistor Test

Climate Control Unit Removal and
Installation

POWER TRANSISTOR

JUMPER
WIRE

1. Disconnect the 4P connector from the power

transistor.

2. Measure the resistance between the No. 1 and

No. 2 terminals of the power transistor. It should be
about 1.4

1.5 k

• If the resistance is within the specifications, go to

step 3.

• If the resistance is not within the specifications,

replace the power transistor.

3. Carefully release the lock tab on the No. 4 terminal

(BLU/YEL) (A) in the 4P connector, then remove the
terminal and insulate it from body ground.

4. Reconnect the 4P connector to the power transistor.

5. Supply 12 volts to the No. 4 cavity with a jumper

wire.

6. Turn the ignition switch ON (II), and check that the

blower motor runs.

• If the blower motor does not run, replace the

power transistor.

• If the blower motor runs, the power transistor is

OK.

1. Remove the climate control unit (A) from the

dashboard, then disconnect the 30P connector (B).
Be careful not to damage the control unit or the
dashboard.

2. Install the control unit in the reverse order of

removal. After installation, operate the control unit
controls to see if they work properly.

3. Run the self-diagnostic function to confirm that

there are no problems in the system (see page
21-8).

(To 12 V power
source on vehicle)

Climate Control Unit Bulb
Replacement

Dust and Pollen Filter Replacement

1. Discharge the static electricity (which accumulated

on you when you removed the climate control unit)
by touching the door striker or other body parts.

2. Remove the self-tapping screws, then carefully

separate the climate control unit to the display (A)
and the control unit (B). Do not kink or pull on the
wires between the display and the control unit. Do
not touch the electronic components on the printed
circuit board in the control unit.

3. Remove the bulb(s) with a flat-tip screwdriver.

4. Install the bulb in the reverse order of removal.

The dust and pollen filters should be replaced every
30,000 miles (48,000 km) or 24 months, whichever
comes first. Replace the filters more often if the air flow
is less than usual.

1. Open the glove box. Remove the glove box stop on

each side, then let the glove box hang down
(see page 20-67).

2. Remove the filter lid (A) from the blower unit, then

pull out the first dust and pollen filter (B). Slide the
second filter to the left, and pull it out.

3. Remove the filter (A) from the housing (B), and

replace the filter.

4. Install the filters in the reverse order of removal.

Blower Unit Removal and Installation

6 x 1.0 mm
9.8 N·m (1.0 kgf·m, 7.2 lbf·ft)

1. Remove the passenger’s dashboard lower cover

(see page 20-67), the right kick panel (see page
20-50), and the glove box (see page 20-67).

2. Cut the plastic cross brace in the glove box opening

with diagonal cutters in the area shown. Remove
and discard the plastic cross brace.

3. Remove the relays (A), then remove the bolts and

the glove box frame (B).

4. Remove the ECM/PCM.

• ’02-04 models (see page 11-284)
• ’05-06 models (see page 11-284)

5. Disconnect the connectors (A) from the blower

motor, the power transistor, and the recirculation
control motor, then remove the wire harness clips
(B).

6. Remove the mounting bolts, the mounting nut, and

the blower unit.

7. Install the unit in the reverse order of removal.

Make sure that there is no air leakage.

Cut here.
