Window Antenna Wire Repair
NOTE: To make an effective repair, the broken section
must be no longer than one inch.
1. Lightly rub the area around the broken section with
fine steel wool, then clean it with alcohol.
2. Carefully mask above and below the broken portion
of the window antenna wire with cellophane tape.
CELLOPHANETAPE
Using a small brush, apply a heavy coat of silver
conductive paint extending about 1/8" on both
sides of the break, Allow 30 minutes to dry.
NOTE| Thoroughly mix the paint betore use.
Check for continuity in the repaired wire.
Apply a second coat of paint in the same way. Let it
dry three hours before removing the tape.

Switch Test
lMake sure you have the anti-theft code for the
radio, then write down the frequencies for the
radio's preset buttons ('99 - 00 models).
Disconnect the battery negative cable, then disconnect
the positive cable, and wait at least three minutes.
Disconnect the driver's airbag connector (see sec-
tion 24).
Remove the driver's dashboard lower cover (see
section 20).
Disconnect the cable reel sub-harness 3P connector
from the main wire harness.

and body ground.
lf there is no continuity, check for an open in the
defogger ground wire.
Touch the voltmeter positive probe to the halfway
point of each defogger wire, and the negative probe
to the negative terminal.
There should be approximately 6 V with the ignition
switch and the defogger switch ON.
