I mentioned this in a past thread before but never got any response as to what could be the cause of this..

My driver side window goes up and down on its own when it's above 70 degrees outside. Sometimes it will go right down and stay there until the day cools and it goes up back half way. The switch doesn't respond when press down or lifted and you can hear a fast ticking/clicking inside the door. Also just recently my front passenger door makes a high frequency sound whether i use the driver master switch or it's own switch.. The high pitch sound goes away after 5 seconds or so.

Here's the video of my car window.

 

Replace the regulator
