Anyone know why or what would be the cause no power windows or mirror passenger side? Drivers side works fine. This happened one day? This is from any control drivers or passenger side?

Sounds like your right hand door module is bad. I had this problem on my wifes 2003 Tahoe when it was 3 weeks old, and then about 2 weeks ago my Duramax did it. I was unable to my key-less entry at all. And nothing would work on passenger door.
