Both, my passenger and drivers windows shake like crazy when going down and the passenger side makes a horrible noise now too. If I push it down or pull it inward when lowering, it doesnt shake and doesnt make any noise. I tried putting some lubrication on the windows but just changed the way the noise sounds and still shakes. I did a search and did not find anything. Anyone have this problem before? The drivers side has been doing it for 1-2 months now and the passenger side just started today, however, the noise that the passenger side makes sounds like the window is going to shatter... Any one got some advice?

 

i have the same problem, I was just attributing it to the motor or regulators being old or something

 

not sure .. but have you checked the rubber seals that grab the glass when it slides down? I have had some cars in the past that did this.. I messed with those rubber seals and it went away ... just a thought.

 

^^^ Yeah, my first thought is the window seals on the door. If your windows had pollen on them and you rolled them down, you may have gotten a lot of sticky residue on the seals.

I'd spray a dose of windex on both sides of each window, then try putting them up and down a few times to see if it smooths things out.
