My 2001 9-5 Aero refused to push air out of the upper vents (the ones you would use for A/C) the other day. I fooled with the buttons for a while and it started to come out and was OK.
Today, nothing would work and even setting on the lowest temp (LO), the air wasn't really all that cold (and it was 41 F outside).
So I did a reset by pushing Auto and Off simultaneously and it comes up with one error, error 12, which is open or shorted air distribution stepper motor. No big surprises so far.
Apparently you access this stepper motor by removing the glove box. Also it seems the error could occur from the air distribution flap being stuck.
How easy is it to move the flap as they suggest to see if that is the problem? How easy to get at the stepper motor? What are the chances it is the wiring, not the stepper motor itself?
I do have another 9-5 and I could swap boxes too see if that was the problem. How easy to remove the ACC box? As easy as on the 92 9000?
Thanks for any help,
Charles
