Check Filament BIS0010E
1. When measuring voltage, wrap tin foil around the top of the neg-
ative probe. Then press the foil against the wire with your finger.
2. Attach probe circuit tester (in Volt range) to middle portion of
each filament.
3. If a filament is burned out, circuit tester shows 0 or battery volt-
age.
4. To locate burned out point, move probe to left and right along fil-
ament. Test needle will swing abruptly when probe passes the
point.

REPAIRING PROCEDURE
1. Wipe broken heat wire and its surrounding area with a cloth
dampened in alcohol to clean.
2. Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit conductive silver
composition on break with drawing pen. Slightly overlap existing
heat wire on both sides [preferably 5 mm (0.20 in)] of the break.
4. After repair has been completed, check repaired wire for conti-
nuity. This check should be performed 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
5. Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area and
hot air outlet.
If a heat gun is not available, let the repaired area dry for 24
hours.

Precautions to Handle Retractable Power Door MirrorsBIS0010G

Do not manually operate retractable power door mirrors. If mirror
is operated manually, be sure to use the retracting switch to
move mirror fully to the opposite direction until it stops. In this
case, a loud click sound is heard, but it is not abnormal. (If mirror
body is manually moved to the neutral position, door mirror will
have some disturbing symptoms during driving, including vibra-
tion, rough retracting movement, or sometimes no retracting.)
CAUTION:
Tilting mirror body forward with excessive force may dam-
age it.

When operating retracting switch to move mirror from the neu-
tral position to the fully-closed (backward limit) position, at the
beginning of the movement a faint click sound is heard, but it is not abnormal.

RH and LH retractable power door mirror bodies have different mounting angles in the neutral position.
This is why the RH mirror body delays slightly when operated with the retracting switch.
NOTE:

When the retractable power door mirror body is in the neutral
position, if retracting switch is operated to the opening direc-
tion while pressing it forward, mirror body is moved to the for-
ward limit position, but it is not abnormal. In this case, be sure
to operate retracting switch to move mirror to the fully-closed
(backward limit) position.

When the retracting switch is operated continuously 5 times
or more, the retractable power door mirror may be inactivated
to prevent overheating. In this case, wait for approximately 5
minutes to recover.
