I think you might not be alone with this problem. My own personal experience has been that SOMETIMES the A/C is great and SOMETIMES it’s not.
Take for example on a “mild” but very clear sunny day of about 75 here in the SF California Bay Area the A/C SOMETIMES feels like it’s barely working. Yep, I crank the temp. down to 62 and all is hunky dory. BUT, I’ve been in Palm Springs Ca. at clear sunny 112 temps. and the A/C, set at 68, kept the interior quite comfortable. Also, it seems that the ACC wants to default too easily to a quiet fan speed at the expense of passenger comfort. Any others noticed that?
In my humble opinion the Saab ACC program mapping is not yet perfected. The sensor on your dash apparently measures the incoming sunlight, it’s angle, and correlates that with outside temperature, inside cabin temperature, various bits of engine data and then the ACC comes up with the right amount of A/C (or heating) and recirculation. Unfortunately, this just doesn’t seem to all come together properly.
We have the same problem with the ACC on the ’98 SE Convertible, so maybe it’s another one of those Saab “quirks.” Durnit, for a car with such other good engineering you’d think they could get this right. My former Mazda Millenia had a WONDERFUL ACC system. Someone got it right there.
Here’s a suggestion that possibly could help a bit. I’m not sure this is a real solution or just my imagination, but I like to think it helps. I wonder sometimes if the ACC just gets plain “confused or overloaded” from too much button pushing and input. So, when it doesn’t seem to be working, I shut the whole system off for about 5- 10 seconds and then start it up again pushing the AUTO button. It might help and then again, it might not. Experiment and see if it works for you. Also, I’ve found that putting the on the air recirculation sometimes helps, especially I more humid conditions.
One final suggestion would be to check your owner’s manual and go through the program to allow the ACC to do the self diagnostic test (resets any faults it finds). I usually find that there are no faults and this doesn’t seem to correct any problem, but might be worth a try
