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

Edit
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.
