Need to adjust how far up the window goes - HELP

[ck42]

Just got done replacing that little teflon rectangular peice that goes in the slide at the bottom of the window....

Now, I noticed for the first time while rolling the window up that it appears to go up TOO far and actually causes some flexing of the door-window top piece (forget what's called).

This woud seem to answer the issue I've had with a small amount of wind noise coming from that window...I've noticed that rolling it down just slightly causes the noise to go away.

So, I suspect that the extra movement upwards is flexing the top part of the door channel and allowing for air to seep in.

In any case, is there a way to adjust how far up the window goes? AND, how does the motor know when to stop going up? (or does it NOT know and just runs out of steam when it hits the limit and keeps trying)?
