I have a 2007 Chevy avalanche ltz and it blows hot air when ac is on on the driver side and cold to the passenger side. I need help on what the problem could be.

If the battery went dead or was disconnected just prior to this happening I would recommend performing a system recalibration. If that did not happen then I would recommend replacing the driver’s side temperature door actuator.
