Windows that stick when going up..

[Genpatton]

Hello everyone, I just joined. Please be patient with me..
I live in Vancouver, Canada and purchased the VERY last 2007 Liberty in Western Canada. Brought it out from Northern Manitoba by train! I really wanted that year and model so it was worth it. However I am noticing something and wanted some help. The Jeep went from a very cold climate where it had sat on the Dealers lot for six months, to a moderate climate. All of the power windows stick. I have had the Dealer spray some lubrication on the sides of the windows and that seemed to work for a while, but now on one or two are sticking again. Any ideas? similar issues? I thought I saw something on this on another site, but cannot find it now for the life of me. Thanks to everyone who reads this and much thanks to someone who might have some suggestions. I still LOVE the vehicle.
By the way, there are lots of SUV's, there is only one Jeep...

Do you mean they sort of chattter or bounce when going up & down?(can't think of a better way to explain it) if so mine do that all the time.

When I bought my '07 the passenger side would get real slow from about the halfway down point to all the way down. Once it passed the halfway point it would speed up.

The dealer had to adjust the track/mechanism inside the door to fix that but they all still do the chatter/bounce thing.

Hey Toonman4.
Thanks for the quick response. I had exactly what you described, the Window gets real slow from about halfway down. I will take it to the Dealer for an adjustment.
Thanks again.

Spray Silicone or White Lithium grease in the window tracks.
