Passive Seat Belts
Table b. Passive Seat Belt Continuity Checks
Operation
The passive seat belt consists of a motor-driven, two-point
diagonal strap and manual lap belt. The diagonal strap is controlled and monitored by the logic box (306). The belt travel is
controlled by two limit switches at the A pillar and at the B pillar. A warning lamp on the dash (47S) will flash or remain continuously lit if a fault is detected in the seat belt travel. The
passive seat belt fuses, relays, and logic box are located under the rear seat on the driver's side.
WARNING
If the seat belt warning lamp on the instrument cluster lights
up at any time, do not drive the car. Have an authorized Saab
dealer inspect and correct any faults in the system before the
car is driven.

making any measu rements.
1. Check the fuses under the rear seat. Also check fuses
5, 12, and 13 in the main fuse relay panel (22).

Operation
Component Locations
Each power mirror is controlled by a four-way switch. Horizontal mirror movement is controlled by a motor in the mirror
assembly. Vertical movement is also controlled by the same
motor and a solenoid. On , 988 and later models, the mirror
glass is electrically heated and is controlled by the heated rear
window circuit. See Heated Rear Window elsewhere in this
section.
See 830 Doors, Windows, and Lids for more information
on removing the power mirrors and switches..

Operation
The power windows are controlled by console switches,
and, if applicable, door-mounted switches. Electric motors in
each door raise and lower the window. Motor direction is controlled by changing the voltage polarity at the motor. On 4door cars, a lockout sWitch-labelled ON/O FF allows the driver to disable operation of the rear power windows.

can be found in 364 Electric Controls and Switches for replacing the switch and switch illumination bulbs.
Fault Tracing
1. Check the fuses. Check the power supply to the switch.
2. At the window motor, check for battery voltage with the
switch pushed in one direction. Reverse the test leads
and push the switch in the other direction. There should
again be battery voltage.
