9-5 blend door problem

Hi everyone.

My 2001 9-5 has started to have that common problem where it only blows hot air on the drivers side. Passenger gets hot or cold but the heater is stuck on for the driver. Ran the ACC calibration which returned a big 0 but I suspected that it was a typical stopper arm, shaft problem.

Tore down under the dash to confirm but was surprised to find both usual suspects intact. the stepper motor still turns the shaft as well as can be expected, and the arm isn't broken.

Puzzled, I ran the hot and cold while hanging out underneath the dash with a flashlight. I noticed that while the motor managed to turn the arm, the door itself or drum or flap or whatever that circular piece is called seemed to be stuck.

I was able to free it by pushing gently with a screwdriver a few times and now it turns easily by hand, however still nothing on it's own. I was wondering if anyone has encountered a similar problem? Where do I go from here as I dont see a way to get behind this part without removing the heater box entirely?

Someone please help me out.

Sometimes the shaft that actually moves the flap breaks, like inside the box underneath where the little blend door arms are. You can rig up a wire or something to move the flap manually, but I believe the only way to get at the flap to repair it is to remove the whole climate control box, a job that I wish on nobody.

Often the gears moving the the part does not engage because it slips out of alignment. The cure is to remove the motor and tap the gears back in just a bit.
