ENDGATE WINDOW LATCH NOT RELEASING OR ENDGATE OPENS WITHOUT KEY
Model and Year:
1983-91 S/T TRUCKS
Some owners of 1983-1991 S/T utility vehicles may experience difficulty releasing the rear endgate window latch and/or the endgate may be opened
without a key.
These conditions may be caused by an endgate window latch which has dirt contamination, a deformed spring leg, a missing or broken spring, a bent
release lever, a bent frame or a latch which is misadjusted.
To correct this condition, it is necessary to properly adjust the endgate window latch assembly and/or replace it.
ADJUSTMENT PROCEDURE:
1.
Check for proper window latch assembly adjustment by performing the following steps:
NOTICE:
To open the end gate, insert the key into the lock assembly and rotate the handle COUNTERCLOCKWISE. Turning the key/handle clockwise and
exerting excessive force may result in a broken lock assembly.
*
Hold the window/glass handle and try to move the glass in and out. If the latch is misaligned to the striker, a rattle condition will exist.
*
Inspect the endgate glass for a snug fit against the top and sides of the body opening.
