Before beginning diagnosis for wind noise or water
leaks, verify that the problem was not caused by
releasing the control switch before the sunroof was
fully closed. The sunroof module has a water-man-agement system. If however, the sunroof glass is in a
partial closed position, high pressure water may be
forced beyond the water management system bound-
aries and onto the headlining.

CONTROL SWITCH
DESCRIPTION
Vehicles equipped with a power sunroof utilize an
sunroof control switch. On this model, the sunroof
control switch is located in the overhead console, in
between the two reading lamps. The switch is
mounted in the overhead console with four plastic
retaining tabs, molded into the switch housing.
This switch incorporates four selections of opera-
tion open, auto open, close and vent. The individual
switches in the sunroof control switch unit cannot be
repaired. If one switch is damaged or faulty, the
entire sunroof control switch unit must be replaced.
OPERATION
With the operation of the sunroof control switch,
voltage is directed to the sunroof motor, through the
switch contacts or control module. If the control
switch is depressed and held depressed the voltage
signal is controlled manually through the switch con-
tacts, so when the switch is released the sunroof
stops.
Refer to the owners manual for more information
on the operation of the sunroof switch and system.
DIAGNOSIS AND TESTING
The following test will determine if the sunroof
control switch is operating properly.
(1) Remove the overhead console from the head-
liner (Refer to 8 - ELECTRICAL/OVERHEAD CON-
SOLE - REMOVAL).
(2) Remove the sunroof control switch from the
overhead console (Refer to 23 - BODY/SUNROOF/
CONTROL SWITCH - REMOVAL).
(3) Using an ohmmeter, test the switch terminals
for proper continuity using the table below. If any ofthe terminals do not show proper continuity, replace
the sunroof control switch.
SWITCH POSITION
(DEPRESSED)CONTINUITY BETWEEN
TERMINALS
VENT (V) 3, 4
OPEN (AUTO) 1, 4
CLOSE 2, 4
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the overhead console from the head-
liner (Refer to 8 - ELECTRICAL/OVERHEAD CON-
SOLE - REMOVAL).
(3) Disconnect the sunroof control switch electrical
connector. Depress the connector retaining tab and
pull the connector straight out.
(4) To remove the switch from the overhead con-
sole, push on the back of the switch until it comes
free from the overhead console.
INSTALLATION
(1) Install the switch in the overhead console
assembly. Be certain the switch is securely snapped
in place.
(2) Connect the sunroof control switch electrical
connector. Be certain the switch connector is securely
snapped in place.
(3) Install the overhead console (Refer to 8 -
ELECTRICAL/OVERHEAD CONSOLE - INSTALLA-
TION).
(4) Connect the negative battery cable.
23 - 184 SUNROOFKJ

Use an adjustable vacuum test set (Special Tool
C-3707-B) and a suitable vacuum pump to test the
HVAC vacuum control system. With a finger placed
over the end of the vacuum test hose probe (Fig. 3),
adjust the bleed valve on the test set gauge to obtain
a vacuum of exactly 27 kPa (8 in. Hg.). Release and
block the end of the probe several times to verify that
the vacuum reading returns to the exact 27 kPa (8
in. Hg.) setting. Otherwise, a false reading will be
obtained during testing.
VACUUM CHECK VALVE
(1) Remove the vacuum check valve. The valve is
located in the vacuum supply tube (black) at the
HVAC system vacuum tee.
(2) Connect the test set vacuum supply hose to the
A/C Heater Control side of the valve. When con-
nected to this side of the check valve, no vacuum
should pass and the test set gauge should return to
the 27 kPa (8 in. Hg.) setting. If OK, go to Step 3. If
not OK, replace the faulty valve.
(3) Connect the test set vacuum supply hose to the
engine vacuum side of the valve. When connected to
this side of the check valve, vacuum should flow
through the valve without restriction. If not OK,
replace the faulty valve.
A/C HEATER CONTROLS
(1) Connect the test set vacuum probe to the
HVAC vacuum supply (black) tube at the tee in the
engine compartment. Position the test set gauge so
that it can be viewed from the passenger compart-
ment.(2) Place the A/C Heater Mode Control switch
knob in each mode position, one position at a time,
and pause after each selection. The test set gauge
should return to the 27 kPa (8 in. Hg.) setting
shortly after each selection is made. If not OK, a
component or vacuum line in the vacuum circuit of
the selected mode has a leak. See the procedure in
Locating Vacuum Leaks.
CAUTION: Do not use lubricant on the switch ports
or in the holes in the plug, as lubricant will ruin the
vacuum valve in the switch. A drop of clean water
in the connector plug holes will help the connector
slide onto the switch ports.
LOCATING VACUUM LEAKS
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN AN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
(1) Disconnect the vacuum harness connector from
the back of the HVAC control head(Refer to 24 -
HEATING & AIR CONDITIONING/CONTROLS/A/C
HEATER CONTROL - REMOVAL).
(2) Connect the test set vacuum hose probe to each
port in the HVAC housing half of the vacuum har-
ness connector, one port at a time, and pause after
each connection. The test set gauge should return to
the 27 kPa (8 in. Hg.) setting shortly after each con-
nection is made. If OK, replace the faulty A/C Heater
Control. If not OK, go to Step 3.
(3) Determine the vacuum line color of the vacuum
circuit that is leaking. To determine the vacuum line
colors, refer to the Vacuum Circuits chart (Fig. 4).
(4) Disconnect and plug the vacuum line from the
component (fitting, actuator, valve, switch, or reser-
voir) on the other end of the leaking circuit. Instru-
ment panel disassembly or removal may be necessary
to gain access to some components. See the appropri-
ate service procedures.

(5) Connect the test set hose or probe to the open
end of the leaking circuit. The test set gauge should
return to the 27 kPa (8 in. Hg.) setting shortly after
each connection is made. If OK, replace the faulty
disconnected component. If not OK, go to Step 6.
(6)
To locate a leak in a vacuum line, leave one end
of the line plugged and connect the test set hose or
probe to the other end of the line. Run your fingers
slowly along the line while watching the test set gauge.
The vacuum reading will fluctuate when your fingers
contact the source of the leak. To repair the vacuum
line, cut out the leaking section of the line. Then, insert
the loose ends of the line into a suitable length of 3 mil-
limeter (0.125 inch) inside diameter rubber hose.
STANDARD PROCEDURE - DIODE
REPLACEMENT
(1) Disconnect the battery negative cable and iso-
late it.
(2) Locate the diode in the harness, and remove
the protective covering.
(3) Remove the diode from the harness, pay atten-
tion to the current flow direction (Fig. 5).
(4) Remove the insulation from the wires in the
harness. Only remove enough insulation to solder in
the new diode.
(5) Install the new diode in the harness, making
sure current flow is correct. If necessary refer to the
appropriate wiring diagram for current flow.
(6) Solder the connection together using rosin core
type solder only.Do not use acid core solder.
(7) Tape the diode to the harness using electrical
tape making, sure the diode is completely sealed
from the elements.
(8) Re-connect the battery negative cable, and test
affected systems.
