window will affect the ability of the gas supports to
hold the lift window open.
1. If the gas support system is not working properly,
get a correct replacement part. Very seldom do
gas supports wear out at the same time.
2. Replace a gas support on one side of the car.
3. If lift window falls down, reinstall on the other
side the support removed in step 2.
4. If lift window falls down, replace the support
installed in step 3 with a new gas support.
COMPARTMENT LIB LOCK CYLINDER
The compartment lid lock cylinder on some
models is located in the rear end panel behind the
license plate. On other models, it is in the center rear
end filler section.
The basic method of cylinder attachment where
the lock cylinder is located behind the license plate is
by means of a lock cylinder retainer. Styles with the
lock cylinder in the rear end filler use rivets to retain
the lock cylinder (Fig. 11).
Removal and lnstallation
1. Open rear compartment lid.
2. To
gain access to lock cylinder retainer, loosen
rear end trim panel.
3. Remove pull-down unit (see procedure).
4. Disconnect connector (4, Fig. 13).
5. On
styles with cylinder behind license plate,
remove lock cylinder retainer by pulling retainer
away from lock cylinder and remove cylinder.
With other design, remove tail lamps and center
filler (Fig. 12). Drill out lock cylinder rivets (part
no. 201 1554) using a 6.3 mm
(1/4") drill bit and
remove lock cylinder.
6. To install, reverse removal procedure. Insure that
that gasket mates properly with outer panel to
form a watertight seal. Check for proper
operation of lock cylinder with key. Then install
retainer or new rivets.
REAR COMPARTMENT PULL-DOWN UNIT
The compartment lid lock is staked to the rear
compartment pull-down unit. Service of the lock is not
recommended. If a lock is to be replaced, the entire
pull-down unit will be required.
Adjust
The pull-down unit can be adjusted for proper
lock striker-to-lock engagement. To adjust pull-down
unit, loosen screws (8, Fig. 14) and adjust pull-down
unit as required and tighten screws.

EXTERIOR LAMPS
TAIL LAMPS
Various methods are employed to remove and
install the components of tail lamp assemblies. Figure
28 will provide a quick reference for performing the
basic service operations for each style.
Tail lamp bulbs can be replaced by removing the
plastic wing nuts which retain the lamp assemblies to
the rear end panel and then removing the lamp
assembly.
Do not rework or alter the reflective surface of
tail lamps or side marker lamps. Replace defective
Fig. 29 - Installing Side Marker Lamp parts with new service replacement parts.
EXTERIOR LAMP SEALING
Care should be exercised to prevent waterleaks at
the tail lamp area when sealing surfaces are disturbed.
Damaged gaskets should be replaced.
If new gaskets are not installed, the use
of sealer
(body caulking compound or equivalent) is
recommended at critical areas and where the old
gaskets have taken a set.
SIDE MARKER LAMPS
Some styles have a rear quarter side marker lamp
which operates in conjunction with the tail lamp
circuit. Figure
29 shows the stud and nut method of
retention used to retain the side marker lamp to the
body. Other styles use a wrap around tail lamp
assembly which doubles as a side marker lamp.
