An Open or Short in the Mode

Control Motor Circuit

1. Disconnect the mode control motor 10P connector.

2. Disconnect the climate control unit 30P connector.

3. Check for continuity between the following

terminals of the climate control unit 30P connector
and the mode control motor 10P connector.

Go to step 4.

Repair any open in the wire(s) between the

climate control unit and the mode control motor.

4. Check for continuity between body ground and the

climate control unit 30P connector terminals No. 2,
11, 12, 13, 14, 22, and 23 individually.

Repair any short to body ground in the

wire(s) between the climate control unit and the
mode control motor.

Go to step 5.

5. Turn the ignition switch ON (II), and check the same

terminals for voltage.

Repair any short to power in the wire(s)

between the climate control unit and the mode
control motor. This short may also damage the
climate control unit. Repair the short to power
before replacing the climate control unit.

Check for loose wires or poor connections at

the climate control unit 30P connector and at the
mode control motor 10P connector. If the
connections are good, substitute a known-good
mode control motor, and recheck. If the symptom/
indication goes away, replace the original mode
control motor. If the symptom/indication continues,
substitute a known-good climate control unit, and
recheck. If the symptom/indication goes away,
replace the original climate control unit.

1. Test the mode control motor (see page 21-46).

Substitute a known-good climate control unit,

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

Go to step 2.

2. Remove the mode control motor (see page 21-46).

3. Check the mode control linkage and doors for

smooth movement.

Replace the mode control motor.

Repair the mode control linkage or doors.

A Problem in the Blower Motor

Circuit

1. Check the No. 12 (40 A) fuse in the under-hood

fuse/relay box, and the No. 14 (10 A) fuse in the
under-dash fuse/relay box.

Go to step 2.

Replace the fuse(s), and recheck.

2. Connect the No. 2 terminal of the blower motor 2P

connector to body ground with a jumper wire.

3. Turn the ignition switch ON (II).

Go to step 4.

Go to step 17.

4. Turn the ignition switch OFF.

5. Disconnect the jumper wire.

6. Disconnect the power transistor 4P connector.

7. Check for continuity between the No. 3 terminal of

the power transistor 4P connector and body ground.

Go to step 8.

Check for an open in the wire between the

power transistor and body ground. If the wire is OK,
check for poor ground at G402.

8. Connect the No. 1 and No. 3 terminals of the power

transistor 4P connector with a jumper wire.

9. Turn the ignition switch ON (II).

Go to step 10.

Repair open in the wire between the power

transistor and the blower motor.

10. Turn the ignition switch OFF.

11. Disconnect the jumper wire.

12. Disconnect the climate control unit 30P connector.

13. Check for continuity between the No. 16 and No. 17

terminals of the climate control unit 30P connector
and body ground individually.

Repair any short to body ground in the

wire(s) between the climate control unit and the
power transistor.

Go to step 14.

14. Check for continuity between the following

terminals of the climate control unit 30P connector
and power transistor 4P connector.

No. 4

Go to step 15.

Repair any open in the wire(s) between the

climate control unit and the power transistor.

15. Reconnect the climate control unit 30P connector.

16. Test the power transistor (see page 21-48).

Check for loose wires or poor connections at

the climate control unit 30P connector and at the
power transistor 4P 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.

Replace the power transistor.

17. Disconnect the jumper wire.

18. Disconnect the blower motor 2P connector.

19. Measure the voltage between the No. 1 terminal of

the blower motor 2P connector and body ground.

Replace the blower motor.

Go to step 20.

20. Turn the ignition switch OFF.

21. Remove the blower motor relay from the under-

hood fuse/relay box, and test it (see page 22-62).

Go to step 22.
