I have a 2007 Mazda 3 sedan which I bought about a year ago. Everything on the car was great, until the weather started to get hotter when the windows would sometimes take a moment to "unstick" if you tried to lower them.
Now, the car has after-market tinting on the windows (it was fitted prior to my purchasing the vehicle), and on a particularly hot day about three months ago, both of the rear windows just wouldn't go down any more. I didn't have time to bother with it, but when idly pressing the button one cooler day, one of the rear windows gave a bit of a "pop!" and let go. It's been working just fine ever since.
You can hear the electric motor trying to work when you press the button, and at night you can see that it's drawing power because the headlights dim slightly if you happen to be waiting at traffic lights. I never hold the button down for more than a few seconds for fear of burning out the electric motor. I've had a pretty concerted effort at trying to pull down on the window with my palms while pressing the button but to no avail.
I'm certain that the issue is that the heat has just caused the tinting to stick to the window seal. Can anyone think of how I could get the window seal to "unstick" from the tinting?
