NOTE;
. Check the engine coolant level. and allow the engine to warm up before troubleshooting.
. Any abnormality must be corrected before continuing the test.
. Because of the precise measurements needed. use a multimeter when testing.
o Before performing any troubleshooting procedures check:- Fuses No. 41 11.5 Al, No. 55 (40 A) in the under-hood fuse/relay box. and No. 17 (7.5 A) in the under-dash fuse/relay
box- Grounds No. G401, G402- Cleanliness and tightness of all connectors

Laft mirror inopcrativ!:
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.
t lf the mirror works properly, check the mirror switch.

1. Check for voltage between the No. 3 terminal andbody ground with the ignition switch ON (||).
There should be battery voltage.a lf there is no battery voltage, check for;- blown No. 16 (7.5 A) luse in the under-dash
fuse/rel8y box,- An open in the BLK,iBLU wire.. It there is battery voltage, go to step 2.
2. Connsct the No. 3 tsrminal to the No. 6 terminalwith a iumpsr wire. Both mirrors should gradually
warm up when the ignition switch ON flt).a lf neither mirror warms up, check for an open inthe ORN/WHT wire.. It only on€ lails to warm up, check its mirrordsfogger elem6nt.. lf both mirrors warm up, check ths switch.

Windshield Wiper Motor Test
1.Open the hood, and remove the cap nuts. Carefully
remove the wiper arms so that they do not touch
the hood.
Remove the cowl cover by prying out the trim clips
(see section 20).
Disconnect the 5P connector lrom the windshield
wiper motor.
Test the motor by connecting battery power
ground according to the table.
lf the motor does not run or fails to run smoothiy,
replace it.
5. Connect an analog voltmeter between the No. 5 {+)
and No.3 {-) terminals. and run the motor at low or
high speed.
The voltmeter should indicate 0 V and 4 V or less
alternately.
