I have a 2003 ES300 and no matter what I try, I cannot get the initial programming of the #2 Homelink button to work. I have reset it many times, but the slow flashing light never changes to a fast flashing light when using multiple different remote transmitters. The #1 and #3 buttons are programmed and work fine. Is it possible that only the #2 button is malfunctioning? Is there any way to replace this part?
