I installed the fronts, and the windows would not go all the way up...auto reverse down. It took many tries with starting the window up, and sandwiching the window between the palms of my hands to help it up. Grudgingly, the window eventually seated up, and the passenger side was a total bearcat to get fully up. I hypothesized that if left alone for awhile, the weather stripping would "adapt" to the intruder. I also installed them on a cool day, maybe 55f. About a month later, I opened the driver side window, and thought "oh, crap, I wonder if it will go up by itself...."...it did go up, and did not auto reverse. Has been working fine. No extra noise notice, either. Today was a pretty warm day, and left all four windows cracked about half an inch when wife and I went to lunch. What a difference it made. No more oppressive heat in the cab.
