I had the usual window squeak from the drivers side forward rubber section that could be temorarily treated with an application of ArmourAll to the rubber seals. Then I installed the JDM Side Visors above the windows. Part of the installation involves pulling the top part of the window seals out of their track to attach the visor brackets. Getting the seals back in right was a bit of a challenge but now the windows squeak from the top of the seals. The point is that squeaks from the window seal rubber may be caused by slight shifting or stretching of the rubber in the tracks. Just an idea but maybe some squeaks could be improved by slight adjustments in the rubber one way or another.
