Modifications have been made to the rear window defogger since the start of production for the 1984 Model Year.
^
When the defogger button is pushed, the red indicator light above the push button will come on and current flows to the rear window heating
elements.
^
After approximately 10 minutes the indicator light will go off but the heating elements continue to receive current until the ignition is switched off.
^
Turning off the defogger switch will not interrupt current to the rear window during this time.
