AND NAVIGATION CONTROLS
Refer to the appropriate wiring information for
connector views and pin-outs. Check fuses first that
supply power to the switch pod (IOD fuse). If OK,
continue. If not OK, repair as necessary to continue.
Remove the instrument panel switch pod for test-
ing. First of all check for 12v battery power at termi-
nal 1 of the instrument panel harness connector.
Then check for ground at terminal 12 of the instru-
ment panel harness connector. If OK, continue. If not
OK, repair wire as necessary to continue.
Each EVIC button press and the open Circuit State
will provide a unique resistance, with respect to the
EVIC/NAV Button Analog Common circuit. Refer to
the INSTRUMENT PANEL SWITCH POD RESIS-
TANCE table.

If any of the resistances are not within the specifi-
cations, the entire switch pod needs to be replaced
(Refer to 8 - ELECTRICAL/INSTRUMENT CLUS-

CLOCK
For clock diagnosis, check for 12v battery power and
ground at the instrument panel connector end of the
instrument panel switch pod (terminal 1 - 12v, and ter-
minal 12 - ground). If power and ground are present
and the clock doesn’t work, replace switch pod.
If the set button is inoperative, the complete
switch pod must be replaced.
HAZARD SWITCH
A low side (ground) signal will be provided from
the Instrument Panel Switch Pod to the BCM to indi-
cate that the Hazard button has been enabled (circuit
closed) by a vehicle occupant.
With the switch removed, check continuity between
the hazard switch input and the ground terminal
when the switch is enabled. If continuity is present,
switch is OK. If no continuity, replace complete
instrument panel switch pod.
REMOVAL
(1) Remove the cluster bezel (Refer to 23 - BODY/

REMOVAL).
(2) Remove the three retaining screws holding the
switch pod to the cluster bezel (Fig. 23).
INSTALLATION
(1) Install the three retaining screws holding the
switch pod to the cluster bezel.
(2) Install the cluster bezel (Refer to 23 - BODY/
