11. Check for continuity between body ground and climate control unit 32P connector terminals No. 28,
29, and No. 30 individually.
Repair short to body ground in the wire(s)
between the climate control unit and the navigation
unit.
Go to step 12.
12. Reconnect climate control unit 32P connector.
13. ’06-08 models: Disconnect navigation unit connector F (5P).
’09 model: Disconnect navigation unit connector D
(12P). 14. Connect climate control unit 32P connector
terminals No. 28, 29, and No. 30 with a jumper wire.
15. Turn the ignition switch to ON (II).
16. Press the RECIRCULATION and OFF buttons. Troubleshoot the navigation system: ’06-08
models (see page 23-130), ’09 model (see page
23-346).
Substitute a known-good climate control unit,
and recheck. If the symptom goes away, replace
the original climate control unit.

1. Remove the in-car temperature sensor (see page21-67).
2. Test the in-car temperature sensor while holding it in front of the dashboard center vent.
 Measure the resistance with the system set to Max Cool.
 Measure the resistance with the system set to Max Hot.
3. Compare the resistance reading between terminals No. 1 and No. 2 of the in-car temperature sensor
with the specifications shown in the graph; the
resistance should be within the specifications.
4. If the resistance is not as specified, replace the in-car temperature sensor (see page 21-67). 1. Remove the center panel:
 ’06-08 models with navigation (see page 23-155)
 ’06-08 models without navigation (see page23-80)
 ’09 model with navigation (see page 23-355)
 ’09 model without navigation (see page 23-256)
2. Remove the self-tapping screw and the in-car temperature sensor (A) from the center panel (B).
3. Install the sensor in the reverse order of removal. Be sure to connect the air hose securely.

2. Remove the dials (A), the self-tapping screws, and the climate control unit (B).
3. Install the control unit in the reverse order of removal. After installation, operate the various
functions to see whether works properly.
4. Run the self-diagnostic function to confirm that there are no problems in the system (see page
21-11). 1. Open the glove box. Remove the glove box stop on
each side, then let the glove box hang down
(see page 20-104).
2. Remove the dust and pollen filter assembly (A) from the evaporator.
3. Remove the filter (A) from the housing (B), and replace the filter.
4. Install the filter in the reverse order of removal. Make sure that there is no air leaking out of the
evaporator.
