16. Check for continuity between the No. 14 terminal of
climate control unit connector B (26P) and the No. 1
terminal of the power transistor 5P connector.
Go to step 17.
Repair open in the wire between the climate
control unit and the power transistor.
17. Check for continuity between the No. 14 terminal of
climate control unit connector B (26P) and body
ground.
Repair short to body ground in the wire
between the climate control unit and the power
transistor.
Go to step 18.
18. Reconnect climate control unit connector A (8P) or
B (26P).
19. Test the power transistor (see page 21-120).
Check for loose wires or poor connections at
climate control unit connector A (8P) or B (26P) and
at the power transistor 5P 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.
20. Turn the ignition switch OFF, and check the No. 56
(40A) fuse in the under-hood fuse/relay box, and
No. 3 (7.5A) fuse in the driver’s under-dash
fuse/relay box.
Go to step 21.
Replace the fuse(s), and recheck.
21. Connect the No. 2 terminal of the blower motor 2P
connector to body ground with a jumper wire.
22. Turn the ignition switch ON (II).
Go to step 23.
Go to step 38.

23. Turn the ignition switch OFF.
24. Disconnect the jumper wire.
25. Remove the blower motor high relay, and test it
(see page 22-88).
Go to step 26.
Replace the blower motor high relay.
26. Connect the No. 4 terminal of the blower motor
high relay 5P connector to body ground with a
jumper wire.
27. Turn the ignition switch ON (II).
Go to step 28.
Repair open in the wire between the blower
motor high relay and the blower motor.
28. Turn the ignition switch OFF.
29. Disconnect the jumper wire.
30. Turn the ignition switch ON (II).
31. Measure the voltage between the No. 1 terminal of
the blower motor high relay 5P connector and body
ground.
Go to step 32.
Repair the open in the wire between the
blower motor high relay and the No. 3 fuse in the
driver’s under-dash fuse/relay box.
32. Turn the ignition switch OFF.
33. Check for continuity between the No. 5 terminal of
the blower motor high relay 5P connector and body
ground.
• Without Navigation System: Go to step 34.
• With Navigation System: Go to step 36.
Check for an open in the wire between the
blower motor high relay and body ground. If the
wire is OK, check for poor ground at G401.
