i know it will sound weird i had the same problem and when i changed my battery it started working again, otherwise some one had told me that there are springs that open the valves and that could be it also

SOURCE: Impala has dual climate control. AC blows cold on

with a dual climate control system, it is imperative for a proper refrigerant charge to be maintained. the symptom you describe is a possible indicator of low charge on the system. the ac evaporator core is closest to the right side of vehicle thereby making air feel cooler on that side, on the left side of the vehicle the cooled air has farther to travel and warms up from cabin air before it discharged from the vents. this is the most probable issue for your vehicle...however if the charge is accurate, the issue would be more so in the air temperature doors which is located deep inside the dash...i hope this helps...good luck!

yes they are they take the miniture bulbs to replace them you must remove the four screws holding them on from the back side 5/16ths to get them off then slide out and allow to drop down follow wires and twist sockets out to remoce aocket and replace bulbs, ther are 4 bulbs in the dash console for ac and heat.

SOURCE: How to remove the dash

I believe yours goes from one side to the other. There are two screws, one on each side, remove the fuse covers to acess them. then there are two screws in the panel above the instrument panel. The rest is just clips that pull out, put the steering wheel in the down position and carefully start pulling the panel off, working from the drivers side to the passenger side. it will come out you just have to be careful around the steering wheel.

unfortunately the bulb is not replaceable, and you will have to replace the entire unit.
