Driver's side inside heat vent always blows out hot air!!!

I have 2001 Avalon XL. The heat is always blowing on the drive side while the passenger side blowing cool. One I put on the air conditioning it will become cool but it seems their is a air balance problem, is there a way to control or balance?

Does your XL have dual zone controls? If it does, there might be a problem with the control unit itself, or the doors in the HVAC system that direct the air.

The unit is a basic setup that does not provide the dual controls that the xls or limited provide. I was thinking to possibly purchase the xls unit but my seats do not have the heat control on them. Suggestions or recommendations?
