Door Handle Plunger Adjustment
If the door handle becomes inoperative, it can either
be adjusted or replaced. The following is a procedure
for adjusting the exterior door handle plunger.
1. Determine the amount of free play in the door
release plunger by pushing in on the plunger
until it just contacts the door release mecha-
nism. Measure the distance that the plunger
travels (Figure 2-5) from this position to where
the plunger is fully released.
2. Remove door panel.
a. Remove hair pin clip (1, Figure 2-6) and bolt
(2) from the door check strap closest to the
door.
b. Remove 2 capscrews (3), which hold the
door strap bracket to the door.
c. Disconnect wiring harness (4) to the window
regulator.
d. Open the door as far as possible in and
remove the internal door panel.
e. Before removing all door panel mounting
screws, support the panel to prevent the
assembly from dropping. Remove 15 mount-
ing screws (5).
NOTE: Remove panel screws across the top last.
NOTE: Door glass and internal door panel will
drop when door panel screws are removed.
• Carefully lower the door panel a few inches. Hold
glass at top to prevent it from dropping. Slide the
door panel toward the cab to disengage the
window regulator roller (Figure 2-7) from the track
on the bottom of the glass. Slide the panel away
from the cab to disengage the other top roller and
lower roller from its tracks. Place the panel out of
the way after removal.
a. Lift door glass and support at the top of the
frame.
b. Remove 2 screws (Figure 2-8) holding the
roller track to the bottom of the door glass.
3. Remove capscrew and nut from inside release
lever (1, Figure 2-14).
4. Remove the four mounting screws that holds the
latch mechanism in the door (2).
5. Remove door latch mechanism (4). Check to
see if door latch mechanism works properly by
performing the following test.
a. Close latch mechanism pawls
b. Operate inside door release lever to see if
pawls open. If pawls do not open, replace
assembly.
c. Close pawls again.
d. Press the outside door button to see if pawls
open.
e. If mechanism operates properly go on to
STEP 6. If mechanism does not work prop-
erly, replace with a new door latch assembly
then continue with STEP 6.
6. Remove the mounting screws (3) from the out-
side door handle. With the door handle
removed, adjust the plunger counter clock wise
to increase the height of the door handle
release button. Lock the plunger capscrew with
locking nut. Apply lock tight to prevent screw
from working loose.
7. Reassemble door assembly by reversing the
previous steps.
