BLEND DOOR OR CONTROL HEAD?

1999 Buick Park Avenue

Air Conditioning problem
1999 Buick Park Avenue 6 cyl Front Wheel Drive Automatic 56000 miles

I have a 99 park ave ultra with dual climate control. The air comes out slightly cool on the passenger side, but comes out hot on the drivers side. I have the dash apart but cannot seem to locate where the blend doors are. Any insight to this? Also, would the control head cause this?
