The drivers side window on my 03 4 door Blazer won't always go into the channel when I try to close it if I am on the highway with a cross wind. Is there any way to adjust this? One mechanic I talked to said there isn't any adjustment for this. Or is he wrong?

If there is no adjustment I was thinking of just getting some in-channel Ventvisors. I'm thinking that would force the window into the channel. Anyone with them that can confirm this would work? If I go this route I just want to get a set of 2 for the front doors only. Can anyone tell me if the doors are the same size from the 2 door to 4 door so I can just order a set for a 2 door?

Thanks.....BB
