a/c problem works on passenger side not on drivers side on 2001 Buick LeSabre

Recently recharged a/c system and have been getting cold air on the passenger side but not from the driver side. Checked for vacuum leaks but nothing apparent. Any suggestions?

If the car does not have dual zone climate control, then the problem is a low freon charge in the system. It will not be apparent if just looking at freon gauge pressures- they will be normal. But a system that is 1/2 pound low will cause the passenger side vents to blow cool or cold air, and the drivers side to be less cool or even warm and this car. There is simply not enough freon in the system to cool the air to the drivers side. If it does have dual zone, then the drivers side temperature actuator motor has failed. This actuator controls the temperature door for that side. Dual zone systems have a temp door for each side.

How do I know if I have dual zone climate control?
