I had the same problem as others here with drivers side of dual zone a/c not cooling properly. I tried the resets suggested by other members but the drivers side was still a good bit warmer than the passenger. I removed the actuator, opened it up, and found the contacts to be very dirty and coated with the grease that's on the gears. Using electric parts cleaner and q-tips, I cleaned the small contacts on the gear and the area on the board that the contacts ride on. Reassembled, plugged back in, pulled and reinstalled fuses to do a reset, and problem fixed!! Drivers side is now blowing very cold and doesn't wander around like it did before.

It's kind of hard to see the contacts on the black gear in the pics because they were so dirty.
The whole job took maybe 30 minutes start to finish.
Hope this helps someone who's having the same problem!!
