I have recharged (topped up) the AC on my 2001 Buick LeSabre, but I am still not getting cold air on the drivers side. The air on the passenger side is cold enough, that the AC should not need to be recharged anymore.
If the blend door is the problem, how do you get at it? Is the actuator/motor located on the passenger side to the left of the glove box? Will removing and replacing the actuator/motor solve the problem? What actually goes wrong with the actuator/motor? Is there another blend door actuator/motor on the drivers side?
Actuator motors either get a tear in the rubber or a hose is broken and not letting vacuum assist in its opening.
You can try moving the lever by hand and see if the air gets colder on the bad side.
Check your selector switch and any vacuum hose that open and close vents... first
