TROUBLESHOOTING
The table below will be useful for you in troubleshooting these electrical problems. The most likely causes
of the malfunction are shown in the order of their probability. Inspect each part in the order shown, and
replace the part when it is found to be faulty.

DEFOGGER SWITCH INSPECTION
INSPECT SWITCH OPERATION
(a) Connect the positive (+) lead from the voltmeter to terminal
7 of connector B and the negative (±) lead from voltmeter to
terminal 10 of connector B.
(b) When the switch is off, the voltage should be approx. 12 V.
(c) When the switch is on, check that the indicator light lights up
and that the voltage is less than 1 V.
(d) After 15 minutes, check that the switch is off and the voltage
is approx. 12 V.
A/C AMPLIFIER INSPECTION

DEFOGGER WIRE REPAIR
(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 to the wire.
(e) After a few minutes, remove the masking tape.
(f) Allow the repair to stand at least 24 hours.
MIRROR DEFOGGER INSPECTION
1. INSPECT MIRROR DEFOGGER OPERATION
(a) Connect the positive (+) lead from the battery to terminal 2
and the negative (±) lead to terminal 1.
(b) Check that the mirror becomes warm.
HINT: It will take a short time for the mirror to become warm.
If the mirror does not become warm, replace the mirror as-
sembly.
2. INSPECT MIRROR DEFOGGER CIRCUIT
Disconnect the connector from the outside mirror and inspect
the connector on the wire harness side, as shown.

MIRROR MOTOR INSPECTION
INSPECT MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal 3
and negative (±) lead to terminal 4, check that the mirror turns
upward.
