Supersedes Technical Service Bulletin Group 57 number 09 - 22 dated October 27, 2009 for reasons listed below.
AFFECTED VEHICLES
CONDITION
Door cannot be opened or closed from outside the vehicle in cold weather.
TECHNICAL BACKGROUND
A plastic burr on the bearing bracket can cut the outer sheathing material of the Bowden cable. As a result, water can enter through the outside door
handle and into the sheathing of the Bowden cable. In extremely cold weather, it is possible for the Bowden cable to freeze. In this condition, the
door-opening function of the outside door handle may intermittently or consistently be inoperative until the vehicle is allowed to warm.
When the vehicle is entered through a different door and moved to a location where it can be warmed, the outside door handle becomes operative.
The functionality of the inside door handle is not affected by this condition.
PRODUCTION SOLUTION
Remove all plastic burrs from the bearing bracket and apply a protective fabric cover over the cable to prevent the cable from being cut.
