1999 Toyota Corolla

Electrical problem
1999 Toyota Corolla 4 cyl Front Wheel Drive Automatic 107000 miles

The driver door window stopped working one day. The window was going up and then just stopped. I couldn't get it to go down or up. Eventually I got it to go all the way down but then it would not go back up. After driving on the freeway for about 5 minutes the window went about half way up and every 5 minutes after that I could get it to go up another few inches. I think it may be the window regulator but I am not sure. Any suggestions on what it is and the best way to go about fixing it?

Its a bad window motor. Remove the door panel and unbolt it and install a new one.
