It is always a good idea to replace the U-shaped clip with a
new one when replacing the lock. The old clip may become
distorted and will not hold the lock cylinder properly.

830-11

NOTE

After removing the lid, place small blocks of wood under the
lid hinges to help position the hinge during installation. See
Fig. 27.

NOTE

Front door and hatchback lock motors are mounted on brackets.

Installation is the reverse of removal. Test the central lock
motor before reinstalling the interior trim panels.

CAUTION

The lock motors should not be tested using a battery or power
supply. Damage to the motor may result. Test the motors only
through the central locking control unit.

HATCHBACK AND TRUNK LID
The hatchback or trunk lid can easily be removed. After installation, the fit of the lid should be carefully adjusted.

WARNING

The hatchback lid is very heavy and should not be removed
unless two people, or more, are available to help.

To remove and install hatchback lid
1. Disconnect the negative (-) battery cable. Remove the
ground strap near the hinge. Disconnect the electrical
connectors to the heating element, central locking motor, and any lighting.

Rg. 27. Small blocks of wood (arrow) used to hold lid hinges in up position for lid installation. Be sure to remove the blocks before

shutting the lid.

Installation is the reverse of removal. The lid can be adjusted for proper alignment by loosening the screws at the hinges
or striker plate. Always test the heated rear window and centrallocking functions.

CAUTION

Do not close the hatchback lid if the gas assist struts are not
attached to the lid. The struts and the body could be damaged.

To remove and install trunk lid
2. Mark the position of the hinges using a scribe. Loosen,
but do not remove, the hinge screws.
3. With a helper supporting the rear of the lid, remove the
gas assist struts on each side.

WARNING

• The hatchback lid has no support once the gas assist struts
are removed. The lid could fall causing injury.
• Do not attempt to disassemble the gas assist struts. They
are under very high pressure and could explode.

1. Disconnect the negative (-) battery cable. Disconnect
the electrical connectors next to the left hinge and cut
any wire ties holding the harness to the lid.
2. Mark the position of the hinges on the lid. Remove the
two nuts holding the trunk lid to the hinge mounting.
See Fig. 28.
3. Installation is the reverse of removal. Adjustment to the
lid is made by loosening the nuts shown in Fig. 28.
After completing the adjustment, secure the wiring harness
to the lid and test all electrical functions.

4. Remove the hinge screws that were loosened earlier,
then carefully lift the lid from the body.

NOTE
To replace the drive cables, the interior headliner and the entire sunroof assembly must first be removed. On sedans, the
headliner can only be removed after the rear window has been
removed. Because of the nature of this procedure, it is not
covered in this manual. "

Water drainage hoses are located at the corners of the sunroof assembly. The front hoses run down through the corner
A-pillars. The rear hoses run down through the rear pillars.
These hoses must not be clogged or water may leak into the
passenger compartment.

To remove sunroof

mounting nuts (B) at the hinge holes do not need to be removed.

1. Slide the sunroof back and remove the four screws at
the front edge of the roof panel. See Fig. 30.

NOTE
The opening effort of the assist springs can be adjusted by repositioning the spring end into one of the three openings in the
body. See Fig. 29.

Fig. 30. Screws being removed at sunroof front edge.

2. Close the sunroof panel until a gap of 3/4 in (119 mm)
remains. Then remove the top panel by raising it up at
the front and pulling it forward and out.

SUNROOF
Two types of sunroofs, electric and manual, are installed in
cars covered by this manual. This section covers removal, installation, and adjustment of the sunroof. For troubleshooting
information of the power sunroof see 371 Wiring Diagrams,
Fuses and Relays.

The electric sunroof is driven by a motor and cable assembly. The motor is located in the luggage compartment, near
the spare tire. The drive cables run along each C-pillar up to
the sunroof.

and the clips. See Fig. 31.
4. Working at the rear corners, pry back the locking tabs
for the rear guide nuts. Remove the guide nuts and pull
the rear guides off of the sunroof panel frame. See Fig.

To install sunroof
Before installing the sunroof assembly, lubricate all sliding
surfaces with a coat of petroleum jelly (Vaseline).
1. Install and position the panel frame against the front
stops, center the frame in the sunroof opening and

shown.

3. Have a helper gently press up on the rear edge of the
panel from inside the car and then slide the guide clips
into position.

NOTE
Pressing up on the rear of the panel frame will bend it slightly
allowing the rear guide clips to be pushed back to their original
positions.

4. Tighten the rear guide clip and the rear guide fasteners.
5. Position the sunroof frame as far forward as possible.
6. Install the sunroof panel into the sunroof panel frame,
inserting the back first. Make sure the tab on the panel
engages the spring clips on the frame. Push down and
back on the panel until it locks into place.

SEATS AND SEATBELTS

2. Disconnect the electrical connectors for the seat heater
and power function (where applicable).

The front seats are bolted to the floor pan via rails. The rails
provide fore-aft seat adjustment. All models have heating elements in the front seats. Some models have a power seat adjustment. For information on testing the heating element see

3. To remove the passenger's seat, slide the seat forward.
Remove the nuts holding the rails to the height adjusting mechanism. Remove the seat.

371 Wiring Diagrams, Fuses and Relays.
The seat belts are a combination lap-shoulder belt except for
the center belt for the rear seat. The belts should be inspected
periodically for webbing defects such as cuts or pulled threads.
They should also be tested for proper retracting.

4. To remove the driver's seat, release the front catch by
sliding the seat back to the limit of its travel. Tilt the seat
back and then lift it upward and forward, removing it
from the car. See Fig. 1.

WARNING
• For maximum protection from injury, seat belts should be replaced as a set (including all hardware) if they are subjected
to occupant loading in a collision.
• Seat belts should not be modified or repaired. The seat belt
anchorage points should not be changed or modified.
• Do not install seat belts or seat belt hardware purchased
from an auto-recycler or salvage yard. These parts may have
been subjected to occupant loading from a collision. Only
Saab original replacement equipment mounting bolts and
hardware should be used. Check with an authorized Saab
dealer for the latest parts information.
• Seat belt assemblies must remain together as a matched
set. Improper latching of the seat belt may occur if the components have been mixed from other sets or other cars.
• Do not bleach or dye seat belt webbing. Webbing that is severely faded or redyed will not meet the strength requirements
and must be replaced.

Fig. 1. To remove driver's seat, slide seat to rear (a), tilt seat back (b),
and lift seat out of car (c).
The seat heating elements and thermostat are located under the seat covering. The bottom cover is held on with upholstery clips. The backrest cover can be removed after
removing the headrest and unzipping the cover at the bottom.

To remove front seats
1. Slide the seat to the rear. Remove the two front socket
head screws holding the seat to the adjusting mechanism.

Servicing the passive (motorized) seat belts requires special
equipment and techniques and is therefore beyond the scope
of this manual. See an authorized Saab dealer for repairs to
the passive seat belt system. For passive seat belt wiring diagrams, see 371 Wiring Diagrams, Fuses and Relays.
