Procedure B: Seating Rear Runchannel
1. Check the position of the rear runchannel. The runchannel is the hard-plastic track located between the inner and outer door window weatherstrip.
If the runchannel is correctly seated in the rear track, go to PROCEDURE C. If the runchannel is not seated, use a trim stick and rubber mallet to tap it into correct position.
2. Retest the window operation. If the window operates normally, reinstall the door panel trim and return the vehicle to the customer. (Refer to the NOTE under Procedure A.) If the window is still difficult to operate, go to PROCEDURE C.
