The Interior And Exterior Lights; Daytime Running Light System - Ford 1996 Mustang Manual

Clear away any snow that is on the rear
window before using the defroster. With the
engine running, push the defrost button.
After approximately 10 minutes, the defroster
will turn off. If the window is still not clear,
turn the defroster on again.
The defroster will turn off when the ignition key
is turned to the OFF position.
The heating elements are bonded to the inside of
the rear window. Do not use sharp objects to
scrape the inside of the rear window or use
abrasive cleaners to clean it. Doing so could
damage the heating elements.
