Moonroof
Moonroof Control Unit Input Test
Remove the headliner (see page 20-54).
Disconnect the 5P connector (A) from the control unit (B).
Wire side offemale terminals
Inspect the connector and socket terminals to be sure they are all making good contact.
. lf the terminals are bent, loose or corroded, repairthem asnecessary. and recheckthe system.. lf the terminals look OK, go to step 4.

3. Disconnectthe'13P connector (B) from the switch.
4. Choose the appropriate test based on the
symptom:. Both mirrors don't work, go to step 5.. Left mirror doesn't work, go to step 7.. Right mirror doesn't work, go to step 8.. Defogger doesn't work (Canada), go to step 9.
Both mirrors
5. Check for voltage between the No. 2 terminal and
body ground with the ignitlon switch ON (ll).
There should be battery voltage.. lf there is no battery voltage, check for:- blown No. 14 (10A) fuse in the under'dash
fuse/relay box.- an open in the BLKryEL wire.. lf there is battery voltage, goto step 6.
6. Check for continuity between the No. 6 terminal
and body ground.
There should be continuity.. lf there is no continuity, check for:- an open in the BLK wire.- poor ground (G501).
. lf there is continuity, check both mirrors
individually as described in the next column.

8. Connect the No. 2 terminalto the No. 11 terminal,
and the No. 5 {or No. 13) terminal to the No. 6
terminal with jumper wires. The right mirror should
tilt down (or swing left)with the ignition switch ON
(

).. lf the mirror does not tilt down (or does not swing
left), check for an open in the GRN/WHT (or WHT/
RED)wire between the right mirror and the 13P
connector.
lf the wire is OK, check the right mirror actuator.. lf the mirrorneithertiltsdown norswings left,

9. Connect the No. 1 and No. I terminals with a
jumper wire, and check for voltage between the
No. 2 terminal of the mirror connector and body
ground. There should be battery voltage and both
mirrors should warm up with the ignition switch
oN

t).. lf there is novoltage orneitherwarms up, check
for:- an open in the BLKI/EL or oRN wire.- blown No. 14 ('l0A)fuse in the under-dash
fuse/relay box.. lf only one fails to warm up, check:- its defogger.- poor ground (G501, G502). lf both warm up, checkthedefoggerswitch.

Power Mirror Actuator Replacement
Remove the power mirror (see page 20-15).
Carefully remove the mirror holder from the mirror
housing. Gently pull it out by hand (see page 20-15).
Disconnect the connector.
Remove the cover, then remove the two Torx
screws from the mirror connector.
Record the terminal locations and wire colors.
Cut the wire harness with the wire cutter.
7. Remove the three screws, and separate the mirror
housinq from the mirror base.
