Recently my Chevy Trailblazer started having an issues where all 4 power windows will not stay down. I use the switch to roll any/all of them down and they immediately return to the up position by themselves. What could be the cause?

I am not familiar with Chevy but on Jaguar, Lexus and Toyota if the battery has been replaced or good dead recently the windows and sunroof often need to go through a re learn process so they relearn where full open and full close is. Turn on the engine and allow to run. Operate the window switch to the full up position hold the switch in full up for 5 seconds, wait a second, operate window to full down position and hold in full down mode for 5 seconds. I am curious to know if this procedure works on Chevy!
