Even if you're in a cold area, your AC compressor may still be running, unless ACC is OFF, or in ECON (and I'm not 100% sure about "ECON")
If it does, or even if you're now afraid to start it, BEFORE having it towed to the dealer, check one last thing:
Open the hood. On your left (as you're looking at the car from the position of the front license plate), you will see a bare aluminum (silver-colored) tube running from under the Mass Air sensor, along the frame member, and following the contour of the area past the top of the strut.
Reach in and wiggle it. If you can actually wiggle it, THAT is almost certainly the source of the nasty, clanging, banging, death-knell sound you are getting. There are two plastic brackets that hold the hard AC lines to the frame rails (see linked pages). For whatever reason, the part that holds the high pressure (thinner, bare aluminum) side breaks, and the line gets loose and any vibrations from the valve at the firewall cause the thing to rattle about. Happens mostly when you stop the car.
Fortunately, the swap out is easy, and the parts cheap. I detailed the procedure in this forum back in August (http://www.saabnet.com/tsn/bb/9-5/index.html?bID=180987).
When I first got the noise, I thought the car was dropping parts, or destroying something under the hood. A search here found someone who ID'd the rattling object, and provided an expedient "repair" (plastic tie wrap holding the small tube ti the larger).
Cheap fix.
But, if you've been neglecting your timing belt, I suppose that it could be causing some of these problems, though, from what I know of the system, it would seem to me that you wouldn't get anything "lingering" as a noise (unlike the chain on the 4s), it would pretty much get loose, slip the belt, and (if you're lucky) start running badly, or (if you're not so lucky), eat the valves then & there...
But anyone owning a V6 should change the belt, tensioner & pulleys every 60k religiously.
