Front doors
Door Handle Latch Mechanism
Issues
- Inner handle is too loose and will not pull the latch mechanism far enough forward to release the latch.
- There is no tension adjustment for the cable.
- The cable slips out of the guide very easily as you move the inner door cover away from the door.
- A common fault is improper positioning of the cable in the inner handle mechanism.
Solution
At the back of the door handle mechanism there is a "Guide" - the inner part of the cable must be threaded into the guide (1 in the photo), and the cable jacket fitted into a small receptacle (at 2).
With that done, the cable is positioned properly, the tension is correct, the door handle operates the latch, and springs back to the proper position when released.
