I just installed some of the in channel window vent visors on my FX4 and the passenger side front door was really tight when i was rolling the window up. i had to push with my hands at the same time to get it to go all the way up. Anybody else had this happen? Just doesnt seem right.

 

I installed AVS in-channel and had no problem. All 4 windows roll up fine (slight speed difference at the top but still roll up) so I hate to hear of your trouble.

 

my 07 did that to and after to window solenoids i took them out of the front windows and lived with it. sorry for the bad new but you would like me to be honest i hope

 

Its normal, get them all the way up and leave them closed for a while and the weatherstripping will stretch out and then they will be fine. mine did the same thing when I frist installed them, now they work great. You will notice this problem more if its cold when you put them in as they dont stretch as easy as they do when they are warm.
