lights PONTIAC FIERO 1988 Service Repair Manual

88-2 LIGHTING SYSTEMS AND HORNS
The fog lights must be aimed for proper
illumination of the road. Fog light
aim should be
checked: at least once a year; when a new light housing
is installed; or if service or repairs in the front end area
have (or may have) disturbed the fog light mountings.
FRONT PARKING/TURM SIGNAL
LIGHTS - Pushing either side of the instrument panel
switch will turn on the front parking lights. (Pushing
the left side of the switch will also turn on the
headlights.) When the ignition is on and the turn signal
lever is moved, the appropriate front parking light
flashes to signal a turn. Both lights will flash when the
hazard flashers are on.
If the driver's door is opened when the parking
lights are on, a warning tone will sound. For more
information, see Section
8A-77.
HAZARD FLASHERS - The hazard warning
flasher is part of the turn signal circuit. Pushing in the
button (on the right side of the steering column) will
cause the front and rear turn signal lights, and the front
sidemarker lights, to flash. Pull out the collar around
the button to turn off the hazard flashers.
The hazard flashers will work with the ignition
either off or on. When the hazard flashers are on, the
turn signals do not
work.
The hazard flashers will stop flashing and stay on
brightly if the brake pedal is pushed down.
HEADLIGHTS - The headlights are controlled
by the switch on the instrument panel (to the left of the
speedometer). They will come on whether or not the
ignition is turned on. Pushing the upper left side of the
switch turns on the headlights and causes the headlight
motors to raise the headlights. Pushing the bottom part
of the switch turns off the headlights, and they should
lower.
If the driver's door is opened when the ignition
is off and the headlights are on, a warning tone will
sound. For more information, see Section
8A-77.
Headlight low-beam and high-beam are
controlled by the turn
signal/multifunction lever on
the left side of the steering column. When the
headlights are on, pull the lever toward the steering
wheel until the switch clicks; the lights will change
from low-beam to high-beam, or from high-beam to
low-beam. An indicator light on the center instrument
cluster will come on when the high-beam headlights
are on.
The headlights must be aimed for proper
illumination of the road. Headlight aim should be
checked: at least once a year; when a new headlight
bulb is installed; or if service or repairs in the front end
area have (or may have) disturbed the headlights or
their mountings. The headlight bezels do not need to
be removed to aim the headlights.
Headlight focus is set when the sealed-beam unit
is made; no adjustment for focus is necessary or
possible.
Some state and local laws specify
requirements for headlight aim; these laws
must be followed.
LICENSE PLATE LBGHTS -A light above the
rear license plate will come on when the headlights or
parking lights are on.
LIGHT SWITCH - Most exterior lights are
controlled by the switch on the instrument panel, to the
left of the speedometer. Pushing the upper right part
of the switch turns on the front parking lights, the
taillights and the sidemarker lights. (It also turns on
the instrument panel lights.) Pushing the upper left
part of the switch turns on all these lights plus the
headlights. Pushing the bottom part of the switch turns
off all lights.
In some cases (such as going through a car wash),
it may be desirable to raise the headlights without
leaving the headlights on. To do so, push the upper
right part of the switch to turn on the parking lights.
Then, lightly push the upper right part of the switch;
the headlights will raise but will not turn on.
(Remember that the parking lights and taillights will
stay on.)
For more information on this switch (including
on-car service), see Section
8C. Also see Section 8C for
information on interior lights.
REAR TAlL/STOP/TURN SIGNAL
LIGHTS - The rear tail/stop/turn signal lights are
part of the same light assembly. Pushing either side of
the instrument panel switch turns on the taillights.
When the brake pedal is pushed down, the lights glow
brighter to serve as stoplights.
Moving the turn signal lever when the ignition is
on causes the appropriate rear lights to flash. (If the
brake pedal is held down and a turn is signalled, one
side will flash and the other will stay on brightly.)
All lights will flash when the hazard flashers are
on. However, if the brake pedal is pushed while the
hazard flashers are on, the lights will stop flashing and
stay on brightly.
SIDEMARKER LIGHTS -The front and rear
sidemarker lights will come on when the headlights or
parking lights are on. Both front and rear sidemarker
lights also have reflectors; they will shine when struck
by light, whether or not the car's lights are on.
If the headlights or parking lights are off when a
turn is signalled, the front sidemarker light will flash
in unison with the front turn signal light on the same
side. If the lights are on when a turn is signalled, the
front
sidemarker light and front turn signal light flash
alternately.
TURN SlG N ALS - The front turn signals are
combined with the front parking lights. The rear turn
signals are part of the rear
tail/stop/turn signal lights.
The turn signals work only when the ignition is on, and
the hazard flashers are turned off.
The turn signals are controlled by the turn
signal/multifunction lever on the left side of the
steering column. Moving the lever all the way up or
down (past the detent) will turn on the turn signals.
When the turn is completed, the lever will return to
neutral and the turn signals will stop flashing.
For changing lanes or shallow turns where the
steering wheel does not move far enough to cancel the
signal, move the turn signal lever only to the first
detent. When the lever is released, it will return to
neutral and the turn signals will cancel.
UNDERHOOD LIGHT - The underhood light
will come on when the hood is raised.

ON-CAR SERVICE
Wiring diagrams and other diagnosis information
is given in Section
8A. Information on properly
repairing wiring harnesses, connectors, etc., is on
8A-5.
Most lighting problems are caused by loose
connectors, open or shorted wiring, burned-out bulbs,
bad switches, inadequate ground or blown fuses. Many
of these require only replacement of a defective part.
When replacing a part that requires a special procedure
(such as a lens and housing assembly sealed together),
follow the instructions normally included in the
replacement parts package.
When removing a part that requires special
sealing items (such as sealing washers), be sure to
reinstall those items when replacing the part. Also, if
any body sealing items (grommets, etc.) are disturbed,
be sure to repair them so the passenger compartment
remains properly sealed.

GENERAL DESCRIPTION
INSTRUMENT PANEL AND GAGES
INSTRUMENTS
Instruments consist of fuel gage, temperature
The instrument panel on most cars is a sing,e unit indicator light, generator light, oil pressure indicator
design and all parts attach to the main instrument light, and speedometer. See Section 9F for optional
panel with clips and screws. To service the instrument Gages and tachometer. Service on instruments
panel and components see on-car service information, can be obtained through authorized repair stations.
However, knowledge of instrument circuit checks will
PRINTED CIRCUIT
All models are equipped with printed circuits
which supply current to most instrument panel lights
and instruments. These circuits are made of copper foil
which is die cut and bonded to a polyester base film
(usually mylar). The printed circuit electrical power is
supplied by a connector containing several wires, as
shown in the instrument panel wiring harness
installation instructions. The connector also helps
retain the printed circuit to the speedo cluster. The rest
of the circuit is retained by additional connectors (if
used) and snap-in
bulbs/sockets. For individual
printed circuit diagrams, see Section
8A-80/8 1/82/83,
'Instrument Panel'. help
in determining if operating difficulties lie in the
instrument itself or its related circuit.
Instruments have been designed for easy removal
by elimination of separate wiring. With the wiring
provisions integrated with the instrument panel wiring,
the instruments can be removed after removing the
trim and lens.
SPEED SENSORS
There are three speed sensors currently in use:
1. PINION GEAR; used in mechanical systems
2. PHOTO SPEED SENSORS; used in mechanical
systems
3. PM GENERATOR; used in electronic systems

GENERAL DESCRIPUION
RADIO ANTENNAS
For radios and radio use see the "Radio Fixed Antenna
Operation" section. ETR means 'Electronically Tuned The
fixed antenna on the right front fender
Receiver'. cannot be adjusted up or down. It may provide
improved reception in rural areas.
- The fixed antenna is designed to withstand most
car washes without damage. If the antenna becomes
slightly bent, you can straighten it by hand. The
antenna can be replaced if severely bent (by vandalism,
etc.). Antennas must be kept clean for good
performance.
RADIO
Because radio problems are normally repaired at
authorized warranty repair stations, the tendency is to
remove the set when a problem is reported, without any
preliminary diagnosis. This results in a large number
of radios being "No Trouble Found" units when
received by the warranty repair stations. Often the
trouble can be corrected without radio removal. wire.
If equipped with
A/C, the blower motor has a
built-in capacitor. Extra electrical equipment added to
the static if not properly grounded or wiring was
improperly routed.
Weak
FM station reception will be affected by
nearby buildings, car speed and direction. These
"flutter" and "fading" conditions are characteristic of
weak FM signals.
ETR radios require clock and button reset if the
battery is disconnected.
Popping Noise
