I have a 2001 Saab 9-5 SE Wagon and all of a sudden today, the car quit putting out air through any of the vents on the dash. I checked the forums and websites and everyone suggested re-calibrating the ACC Control system. So I went out to the car and tried that. Of course my display isn't the greatest and its not always readable on the display, so knowing if I have a code or not is difficult. But when I went to reset you can hear a clicking sound behind the dash. Also, when I reset the system it will blow air, but only out of the windshield defrost vents and you can't control any temps or fan speed. Any suggestions would be great.

Those clicking sounds you hear are most probably coming from either the left or right air distribution motor, because the gears are not properly engaging. There is a video on youtube that solves that:

Here is another guide showing you how to take them out:

The distribution motor is on the right side. The yellow plastic bit the motor engages to drive the distribution drum is prone to failure. The gear-train of the motor may be slipping also.

I would get your SID display fixed first so you know what you're dealing with. I just worked on my AC system and I had to purchase a new re-circulation arm, push all the motor gears back into place and install the blend door repair kit.

If you have to work on the drivers side, you'll want to remove the drivers seat as it will make it much more comfortable to work under the dash. It's tight under there.

Also, make sure you test everything before you put it all back together. You'll need to have your display fixed to ensure everything is working properly.

Here's a helpful video.

Good luck!
