REAR DOOR CHUCKING NOISE/REAR DOOR INOPERATIVE

Some 1985-1990 M/L Vans may experience a rear door chucking noise/rear door handle inoperative.
The chucking noise is caused by the door striker contacting the door lock assembly at the fishmouth area. The inoperable door results when corrosion on
the inner lock assembly or latch assemblies causes a increased handle effort or when the spring loaded pivot mechanism separates from the handle.
FIGURE 2
To repair these conditions, a new door lock assembly has been developed which includes a revised fishmouth to allow the door striker to pass more
smoothly through the fishmouth, and a zinc nickel plating to improve corrosion characteristics (P/N 15650814). This new part can be identified by a
green tint where the lock cylinder rod attaches to the door lock assembly (Figure 2).
