James, I am not sure what is going on and don't really know a lot about this stuff.
But I am checking this damn nerdfest because I started a thread in here.
But I googled and searched around a little. If no warning lights indicate a problem, it said that dirt may be a problem. They said it was common in Saabs because the ignition switch is in the center console- but whatever, and I don't think that you get yours too dirty from what I remember; but cleaning it can't hurt.
<BLOCKQUOTE class="ip-ubbcode-quote"><div class="ip-ubbcode-quote-title">quote:</div><div class="ip-ubbcode-quote-content"> once a month the ignition switch be cleaned with Carb cleaner (but
over-spray could damage the interior. especially plastic) or even just
plain water (but I disagree with using just regular water because of
mineral deposit build-up & potential rusting). If a few drops of water
are to be used then use distilled water to do the initial clean up of
the switch. Then after the water I would recommend putting in a few
drops of isopropyl alcohol to absorb any moisture. Then, follow that up
with a few drops of a thin oil to help lubricate it. Once a month is
probably over doing it for most but if you travel on alot of dirt roads
then it might be appropriate for you to clean it that often. </div></BLOCKQUOTE>
