Power Window

Is it a convertible? My did the same thing, then I tried a healthy shot of wd-40 silicone spray and it's fine now. You may have to reapply periodically. Make sure you apply to both sides even if only one side is affected. It was my understanding that the problem stems from the window seals being too tight and the torque limiting window motor stops to keep from burning up or breaking itself, it's a built in safety factor. I chalk it up as the price you pay to have a convertible.
