Have a 2001 grand prix se 3.1.Yesterday all the windows were working well.When i get in the car,being its so hot,i put down the front two windows a little to let heat out before running ac.I put them up again,no problem. next stop same thing,but drivers side will not go down.Passenger side does.I had the regulator in drivers side replaced about 2 years ago.Any help would surely be appreciated. thanks
