Been having this problem with my '06 Silverado too. This winter, driver's side got stuck and wouldn't blow hot, wouldn't change. After looking at youtube, I unplugged the actuator and replugged it and it had been working fine. Just a week and a half ago or so it started randomly switching from hot to cold. On it's own, haven't moved the climate control thing for months. Was hoping it'd be an easy fix I could do here at home. It's my wife's daily driver and needs to run.
