Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.The problem you are describing may be caused by a failing window regulator but in order to determine if in fact that is the case you are going to need to remove the trim panel and inspect it as you roll the window up and down. I have enclosed the steps to check it int he link below. There not the best but its all thats available due to the age of the car.https://dl.dropboxusercontent.com/u/104923897/Door%20regulator%20Mar%2025.pdf
