front windows won't roll down. HELP!

[daffydill]

For the last few months, my front passenger and driver windows have been sporadically operational. On a good day, if I push the window down button enough times, the window may roll down an inch or 2, or I may even be able to use it for an hour at a time or so. I am always able to roll my windows back up, but when it comes time to roll them down, they usually don't work. As of recent, I haven't been able to get them to work in weeks. When I push the switch up, I can hear and see the window slightly push up, but trying to roll them down there is no movement and no sound other than my clicking switch. HELP!

My 04GT does this when it's cold
Try helping the glass a little and it will probably go down
