looking for controller behind glove box

Expert:  Dave Nova replied 2 years ago.
There are two different possible causes for your problem.
1) a/c system undercharged. If refrigerant levels are too low, it will cool on passenger side but not on drivers side. Check the low side line under the hood (larger diameter line) with a/c running. If line is not super cold then this indicates an undercharged system. Add refrigerant until proper cooling is restored.
2) faulty temperature actuator for drivers side. Check #1 above first then if system is cooling properly and drivers side is still warm, let me know and I can give you location of the drivers side actuator.

Thanks for clarifying. Remove the glove box, then look through glove box opening to left (toward drivers side) There you will see the actuator that is likely bad. See attached image.
