Engine Idle Speed Control System
Genuine Ford air conditioning (either
factory-installed or dealer-installed) has an
engine idle speed control system that
compensates for engine speed loss that may
occur when the air conditioning compressor is
running. This idle speed control holds the engine
idle essentially constant, regardless of whether
the air conditioning system is on or off.
If an aftermarket air conditioner is installed, an
engine idle speed control system must be
installed. Otherwise, the engine may not operate
satisfactorily at idle speed and low engine speed,
or the engine may stall.
Rear Window Defroster (If equipped)
Rear window defroster switch
The defroster for the rear window clears frost,
fog, or thin ice from both the inside and outside
of the rear window.
To operate the defroster, push the V (defroster)
switch on the instrument panel to the right of
the steering wheel. The indicator light on the
instrument cluster comes on. When the window
is clear, push the defroster switch again to turn
it off.
