CHECK WINDOW DEFOGGER SYSTEM
Note
If the auxiliary battery voltage becomes low, window defogger operation is canceled to prioritize supplying power to the power steering system.
Turn the power switch on (IG).
Check that the defogger indicator illuminates when the window defogger switch of the air conditioning control assembly is pressed and the back window glass (window defogger wire) warms up.
After approximately 15 minutes, check that the defogger indicator illuminates and window defogger operation stops.
