SUBJECT:
SHEATH DOES NOT HOLD BELT AND BUCKLE IN POSITION AND ASSEMBLY FALLS TO FLOOR (REPLACE BUCKLE ASSEMBLY)
MODELS:
1987-1991 G-VAN
Owners of some 1987-1991 G-Vans may experience a seat belt buckle cover cracking or splitting, which allows the buckle assembly to fall to the floor.
This condition may be corrected by replacing the buckle assembly portion of the seat belt assembly. The new buckle assembly covers are manufactured
with a new forming process that prevents cracks and splits.
SERVICE PROCEDURE:
1.
On the driver's side only: disconnect the seat belt warning wire connector.
^
The connector is located under the seat near the left-front of the seat riser.
^
Attach a long wire or string to the connector to aid in the installation of the new buckle warning wire.
2.
Remove the access plug by prying the plug from the cover with a small screwdriver.
3.
Remove the bolt, washers, and buckle assembly (Figure 1).
Important:
The wave washer is used in 1991 vehicles only.
4.
On the driver's side only thread the warning wire out of the seat riser and remove the string or wire from the connector. Make sure one end of the
string or wire protrudes from the left front of the driver's side seat riser.
5.
On the driver's side only: attach the string or wire to the connector of the new buckle assembly and using the string or wire, pull the seat belt
warning wire through the seat riser.
