What are we doing wrong? We have the vent and side window set in the door but the window will not roll up. I think the out side channel is pushing the window too far in so that it doesn't give enough clearance to go up and down. I know that doesn't sound right but I can't figure out what to do. I think I will disassemble the whole thing and start over. Here are some pictures that will show what I'm talking about better.
