Rear Window Defogger Switch
INSPECTION OF SWITCH
INSPECT SWITCH OPERATION
(a) Connect the positive (+) lead from the battery to
terminal 2 and the negative (±) lead to terminal 3.
(b) Connect terminals 2 and 6 through a 3.4 W test bulb.
(e) Push the defogger switch. Check that the test bulb
lights for 12 to 18 minutes, then the test bulb goes
out.
If operation is not as specified, replace the switch.
Rear Window Defogger Relay
INSPECTION OF RELAY
1. INSPECT RELAY CONTINUITY
(a) Check that there is continuity between terminals 1
and 3.
(b) Check that there is no continuity between terminals 2
and 4.
(e) Check that there is no continuity between terminals 3
and 4.
If continuity is not as specified, replace the relay.
