I started a new thread 'cause I'm at my wits end. I've got the window assy back in the door without scratching it up too badly. But no matter how I try, I cannot get the rubber lip to go out over the window opening around the vent window. I've poked and proded, tried screw drivers and popsicle sticks. I've had the assy screwed down tight and floppy loose. I just can't get the rubber to stay folded out around the opening. Anyone have any tips?
