My Dad just did this on my sister's Mystique, after I read about that Saab clutch last night. She said the A/C wasn't working a few days ago when it was hot weather. It worked fine at idle when I checked it, but I heard an odd squeal when the clutch cycled once. The gap was much more than specifcation, so a thinner washer was installed (made one!) and now the clutch gap is in spec. Hopefully that will fix the problem, can't stress test it now it is 50 degrees .
