NOTE
Also see 853 Dashboard and Consoles for additional cluster
bulb replacement infonnation.
Lighting faults can usually be traced by observing whether
one light is out, or other lights on the same circuit are out. If
only one bulb is out, chances are the bulb has failed. If more
than one bulb is out, there is probably an electrical fault in the
circuit, such as a poor ground connection. Always begin by
checking fuses and connectors. For wiring diagrams and additionallighting information, see 371 Wiring Diagrams, Fuses and Relays.

Replacing Interior Bulbs
The interior dome lights and the glovebox light can be
changed by carefully prying away the clear plastic cover.
Some models have a time delay feature controlled by the
time-delay relay. This relay is located under the back seat on
the left side.
The ignition key light can be changed by peeling away the
shift lever boot on cars with manual transmission or removing
the plastic trim piece around the shift lever on cars with automatic. Then remove the front console and rear console
screws (rear screws are behind rear passenger ashtray).
Carefully lift up the console and pull the bulb from its holder.
NOTE
Remove the ignition key before attempting to remove the console.
All instrument cluster lamps, except the fuel level warning
lamp, can be replaced without removing the cluster. These
bulbs can be accessed after removing the left-front speaker
grille. See Fig. 15.
Fig. 15. Instrument cluster illumination bulbs being replaced
through left speaker grille access hole.
On most 1985 dash-mounted switches, the illumination
bulbs can be replaced once the switch is carefully pried out of
the dashboard. On 1986 and later models, the switch illumination is integral with the switch and the bulbs cannot be separately replaced.

GENERAL
This repair group covers mainly the switches and controls
used throughout the car's interior. Some engine control
switches and instruments are also covered here. For switch
testing, use the wiring diagram schematics found under 371
Wiring Diagrams, Fuses and Relays.
WARNING
1990 and later models are equipped with an airbag or SRS
system. The airbag is a explosive device. Do not attempt to remove the steering wheel or service the wiring in the steering
column assembly. You could accidentally ignite the airbag,
causing serious personal injury. See an authorized Saab dealer for any repairs to the SRS system or to disarm the system
prior to removing the steering wheel.
CAUTION
Always disconnect the negative (-) battery cable before replacing any switches.
Instrument Panel Switches
Most of the switches located in the instrument panel can be
replaced without removing the instrument panel. An exception
to this is the air distribution switch, the heater control knob,
and the extra dimmer switch (rheostat)-which all require removal of the instrument panel as described below.
Fig. 1 shows the headlight switch being removed. After removing the switch, disconnect the wires as shown. The panel switches can be carefully pried away from the panel. See
Fig. 2.
SWITCHES AND CONTROLS
Replacing switches is straightforward and easy to do.
Some switches may need to be adjusted for proper operation
after they are installed. Usually the switches needing adjustment have a threaded body or have mounting screw adjusting
holes. Some of the fasteners are Torx-type bolts and screws.
Plan to have Torx drivers on hand before starting the job. If
you are replacing a switch with many wires, it helps to draw a
picture of the terminals and wire colors. This will prevent hooking up the wires improperly during installation. See 371 Wiring Diagrams, Fuses and Relays for more information on
identifying components and their locations.
WARNING
Always check the function of the circuit after replacing a
switch to verify proper and safe operation.

screws are interchanged, the padded dashboard could be damaged.
Steering Column Stalk Switches and Horn
Switch (1985-1989 models)
The direction indicator and windshield washer switches are
mounted to the steering column. To replace a switch, remove
the lower steering column trim. Then remove the screws holding the switch and disconnect the electrical connector. See
Fig.6.
WARNING
1990 and later models are equipped with an airbag or SRS
system. The airbag is an explosive device. Do not attempt to
remove the steering wheel or service the wiring in the steering
column assembly. You could accidentally ignite the airbag,
causing serious personal injury. See an authorized Saab dealer for any repairs to the SRS system or to disarm the system
prior to removing the steering wheel, stalk switches, or steering column wiring.

To remove the horn switches, carefully pry them away from
the steering wheel. See Fig. 7.
Interior Switches
On 1985 through 1990 models, the power window switches, sunroof switch, and interior light switch can all be changed
by carefully prying the assembly from the center console. See
Fig.8.
• On 1991 and later models, the entire power window/sunroof
switch assembly must be replaced if a single switch is faulty.
The bulb for the switch assembly can be replaced by tuming
the bulb holder 90 0 and removing the bulb. See Fig. 9.
The brake light switch is located on the upper part of the
brake pedal assembly. See Fig. 10. Adjust the switch so the
brake lights come on as soon as the pedal is depressed and
go out when the pedal is in the rest position. For the most accurate adjustment, use the specification shown below.
