Hello,
Working on a 2015 chevrolet cruze. I am installing the window run channel on the driver side. I cannot seem to get it on where it locks on the corner. The portion that has the plastic piece. I was wondering if anyone has done this job could give me a pointer.

The portion of the installation I have trouble with is the top left of the part. Where there is some sort of clip that locks into a pin on the door.
