With the ignition switch in the RUN position, voltage is
applied to the rear defogger switch. When you press the rear defogger control
switch, voltage is applied to the solid state timing circuit. The solid
state timing circuit provides voltage to the following components:
The rear window becomes warm. The warmth removes condensation from the
surface of the window.
The contact in the timing circuit stays closed until one of the following
actions occurs:
| • | You again press the rear defogger control switch |
| • | The timer cycle is complete. |
| • | You turn the ignition switch to the OFF position. |
The first time that you press the rear defogger control switch, the
timing circuit allows the rear defogger to operate for approximately 10 minutes.
After the initial time, each time that you press the rear defogger control
switch, the timing circuit operates for approximately 5 minutes.
The timing circuit resets to 10 minutes when you turn the ignition
switch to the OFF position.
