REPAIR
1. INSPECT WINDOW GLASS (ANTENNA WIRE)
NOTICE:
When cleaning the glass, wipe it in the direction of the wire
with a soft and dry cloth. Take care not to damage the wire.
Do not use detergents or glass cleaners with abrasive in-
gredients. When measuring voltage, wind a piece of tin foil
around the tip of the tester probe and press the foil against
the wire with your finger, as shown in the illustration.
(a) Check the continuity, at the center of each antenna wire,
as shown in the illustration.
2. REPAIR WINDOW GLASS (ANTENNA WIRE)
(a) Clean the broken wire tips with a grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire to be
repaired.
(c) Thoroughly mix the repair agent (Dupont paste No.4817).
(d) Using a fine tip brush, apply a small amount of the mixture
to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours after-
wards.
