REPAIR EQUIPMENT
• Conductive silver composition (DuPont No. 4817 or equivalent)
• Ruler 30 cm (11.8 in) long
• Drawing pen
• Heat gun
• Alcohol
• Cloth
REPAIRING PROCEDURE
1. Wipe broken heat wire and its surrounding area clean with acloth dampened in alcohol.
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 conducted 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.

DOOR MIRROR
Before pulling out the terminal, note the connector terminal arrangement.
2. Turn the mirror glass surface upward.
3. Apply a protective tape A to the housing.
4. Insert a suitable tool B into the concave gap between mirror holder (1) and power unit (2). Push up tabs (3) (2 locations) on
mirror holder to disengage lower part of mirror holder, and
remove mirror body assembly.
NOTE:
When pushing up the tabs, do not forcefully push up only 1 con-
cave position but try to push up 2 concave positions.
5. Remove the mirror body (1) from the mirror housing assembly (2).
6. If necessary, remove screws and mirror actuators.
ASSEMBLY
1. Warm the lower tabs with a dryer or equivalent. NOTE:
Warm the lower tabs sufficiently before installing the mirror body. The tabs may be broken if it is cold. Be
especially careful in the winter.
2. Engage upper tabs of mirror body (1) with power unit (2). Then, press lower part of mirror glass down until the lower part snaps
to allow engagement of lower tabs.
NOTE:
After installation, visually check that the lower tabs are securely
engaged when viewed from the bottom of mirror surface.
3. Insert the harness terminals into the connector. NOTE:
Make sure to insert the harness terminals into the correct con-
nector. Do not confuse the locations.
