29. Measure the voltage between the blower motor

relay 4P socket terminal No. 1 and body ground.

Go to step 30.

Replace the under-hood fuse/relay box

(see page 22-65).

30. Turn the ignition switch to ON (II).

31. Measure the voltage between the blower motor

relay 4P socket terminal No. 3 and body ground.

Go to step 32.

Repair open in the wire between the No. 36

(10 A) fuse in the under-dash fuse/relay box and the
blower motor relay.

32. Turn the ignition switch to LOCK (0).

33. Check for continuity between the blower motor

relay 4P socket terminal No. 4 and body ground.

Repair open in the WHT wire between the

blower motor relay and the blower motor.

Check for an open in the wire between the

blower motor relay and body ground. If the wire is
OK, check for poor ground at G301 (see page 22-64).

1. Clear the DTC with the HDS.

2. Turn the ignition switch to LOCK (0), and then turn

to ON (II).

3. Do the self-diagnostic with the HDS (see page

21-10) or climate control unit (see page 21-11).

4. Check for DTCs.

Go to step 5.

Intermittent failure.

5. Turn the ignition switch to LOCK (0).

6. Disconnect the recirculation control motor 7P

connector.

7. Disconnect the climate control unit 32P connector.

8. Check for continuity between the following

terminals of climate control unit 32P connector and
the recirculation control motor 7P connector.

32P:

7P:

No. 15

No. 1

No. 16

No. 2

Go to step 9.

Repair open in the wire(s) between the

climate control unit and the recirculation control
motor.

9. Check for continuity between body ground and the

climate control unit 32P connector terminals No. 15
and No. 16 individually.

Repair short to body ground in the wire(s)

between the climate control unit and the
recirculation control motor.

Go to step 10.

10. Test the recirculation control motor (see page

21-74).

Substitute a known-good climate control unit,

and recheck. If the symptom/indication goes away,
replace the original climate control unit.

Replace the recirculation control motor

(see page 21-74), or repair the recirculation control
linkage or door.

3. Do the self-diagnostic with the HDS (see page

21-10) or climate control unit (see page 21-11).

4. Check for DTCs.

Go to step 5.

Intermittent failure, check for loose wires or

poor connections on the recirculation control motor
circuit.

5. Turn the ignition switch to LOCK (0).

6. Test the recirculation control motor (see page

21-74).

Go to step 7.

Replace the recirculation control motor

(see page 21-74).

7. Disconnect the recirculation control motor 7P

connector.

8. Disconnect the climate control unit 32P connector.

9. Check for continuity between the following

Check for loose wires or poor connections at

the climate control unit 32P connector and at the
recirculation control motor 7P connector. If the
connections are good, substitute a known-good
climate control unit and recheck. If the symptom/
indication goes away, replace the original climate
control unit.

Repair open in the wire(s) between the

climate control unit and the recirculation control
motor.

CLIMATE CONTROL UNIT 32P CONNECTOR

1. Check the No. 36 (10 A) fuse in the under-dash fuse/

relay box.

Go to step 2.

Replace the fuse, and recheck. If the fuse

blows again, check for a short in the No. 36 (10 A)
fuse circuit.

2. Disconnect the climate control unit 32P connector.

3. Turn the ignition switch to ON (II).

4. Measure the voltage between the climate control

unit 32P connector terminal No. 3 and body ground.

Go to step 5.

Repair an open in the wire between the No. 36

(10 A) fuse in the under-dash fuse/relay box and the
climate control unit.

5. Turn the ignition switch to LOCK (0).

6. Check for continuity between the climate control

unit 32P connector terminal No. 5 and body ground.

Check for loose wires and poor connections

at the climate control unit 32P connector. If
connections are good, substitute a known-good
climate control unit and recheck. If the symptom/
indication goes away, replace the original climate
control unit.

Check for an open in the wire between the

climate control unit and body ground. If the wire is
OK, check for poor ground at G504 (see page 22-64).
