REAR WINDOW DEFOGGER
SWITCH
DESCRIPTION
The switch for the rear window defogger (EBL) sys-
tem (Fig. 6) is integrated into the A/C-heater control,
which is located in the center of the instrument panel.
When the rear window defogger switch is activated, the
timing circuit integral to the A/C-heater control operates
the rear window defogger (EBL) relay.
When the EBL relay is activated, current is
directed to the rear defogger grid lines. The grid lines
heat the glass to help clear the surface of fog or frost.
OPERATION
An LED indicator will illuminate when the rear
window defogger switch is activated. When the
switch is activated, the A/C-heater control operates
the rear window defogger (EBL) relay. The EBL relay
controls the current flow to the grids of the rear win-
dow defogger.
NOTE: The EBL system turns off automatically after
ten minutes of initial operation. Each following activa-
tion cycle of the EBL system will last five minutes.
The EBL system will initially be on for approxi-
mately ten minutes or until the rear window defog-
ger switch or the ignition switch is turned off. After
the initial time interval has expired, if the defogger
switch is turned On again during the same ignition
cycle, the EBL system will automatically turn off
after about five minutes.
The rear window defogger switch and the rear win-
dow defogger LED indicator cannot be repaired and,
if faulty or damaged, the A/C-heater control must be
replaced (Refer to 24 - HEATING & AIR CONDI-
TIONING/CONTROLS/A/C-HEATER CONTROL -
REMOVAL).
