1998 HONDA CIVIC 23-2

Switch Input Test
CAUTION: Be careful not to damagc the rear window
defogger switch or the center panel when prying the
switch out.
NOTE: Before testing, check for blown No. 16 (7.5 A)
fuse in the under-dash fuse/relay box,
1. Pry the switch out of the center panel (see section 20).
2. Disconnect the 5P connector from the switch.
3. Turn the jgnition switch ON (ll), and check the voltage
between the BLVBLU {+) and the BLK (-)terminals.
There should be battery voltage
. lf there is no voltage, check for an open in the
BLVBLU wire.
. lfthere is baftery voltage, go to step 4.
Wire side of famale terminals
connect a jumper wire between the BLK/BLU and
the BLU/YEL terminals.
Turn the ignition switch ON (ll), and check that the
rear window defogger works; if it does. replace the
defogger switch.

Both inoperative:
1. check for voltage between the No. 2 (BLVYEL) ter
minal and body ground with the ignition switch ON
0 r).
There should be batterY voltage
. If there is no voltage, check for:
- blown No. 17 (7 5 A) fuse in the under-dash
tuse/relay box- an open in the BLK'/YEL wire.
o lf there is battery voltage, go to step 2.
2. Check for continuity between the No 4 (BLK) termi-
nal and body ground.
There should be continuity.
. lf there is no continuity, check for:
- an open in the BLK wire.
- poor ground (G551).
Left mirror inoporalive:
connect the No. 2 {BLK/YEL) terminal of the 10P connec-
tor to the No. 3 (YEURED) terminal and the No 5 (or No
6) terminal to body ground with jumper wires The left
mirror should tilt down (or swing left) when the ignition
switch is turned ON (ll)
. lf the mirror does not tilt down (or does not swing left),
remove the left door panel. and check for an open in
the BLU/WHT (or BLU/BLK) wire between the left
power mirror and the switch
- lf the wire is OK. check the left power mirror actua-
tor.
lf the mirror neither tilts down nor swings left. repair
the YEURED wire.
lf the mirror operates properly, check the mirror switch'
Right mirror inoperative:
Connect the No. 2 (BLK /EL) terminal of the 10P connector
to the No. 3 (YEURED) terminal and the No. 9 (or No 8)
terminal to body ground with jumper wires The right mir-
ror should tilt down (or swing left) when the ignition
switch is turned ON (ll).
. lf the mirror does not tilt down (or does not swlng
left), remove the right door panel. and check for an
open in the GRN/WHT (or YEUBLK) wire between the
right power mirror and the switch.
- lf the wire is OK, check the right power marror actu-
ator.
. lf the mirror neither tilts down nor swings left. repair
the YEURED wire
. lf the mirror operates properly, check the mirror
switch.

Connect the No. 1 terminal to the No. 7 terminal. and theNo. 4 (or Nb.9) terminalto body ground with jumper
wires. The left mirror should tilt down (or swing left)with the ignition switch ON (ll).
. lf the mirror does not tilt down (o. does not swinglett), check for an open in the YEURED (or BLUMHT)wire between the left mirror and the 10p connector. lfthe wire is OK, check the left mirror actuator.a lf the mirror neither tilts down nor swings left, repairthe BLU/BLK wire.
