My wife broke the tilt knob off our 2021 suburban driver's seat. What I am stumped on is the removal of the seat side trim in order to get access to the seat controls. I see that there is a screw on both the front and rear of the trim and have removed those. In addition there is a bar that the leading edge clips over. Past that though I can't find any other fasteners. How does this piece come off? There are two part #'s listed for the seat switches that I can find (85667459 and 85030985) before I order the replacement, I need to figure out the correct one. Can anyone help me with how this comes off?
