Sometimes (especially if you're a frequent windshield-sprayer, as I am) the internals of the wiper switch develop carbon deposits that prevent completion of the washer circuit. You may find that your washers will work if you try them from one of the other wiper positions. If they do, then you can clean the contacts yourself. Even if they don't, it might be worth trying anyway. Should you elect to replace the switch, get one from a boneyard for $25-$50 rather than paying for a new one.
Removing the switch involves unscrewing the plastic housing under the steering wheel (T24 torx if I remember, on the underside of the wheel), then unscrewing, disconnecting and removing the stalk switch. With an airbag car, it might be a good precaution to first disconnect the battery -- ask someone with more airbag experience on that score.
Once you have the switch out, you'll need a teensy flat screwdriver to carefully pry apart the plastic tongue-and-groove tabs that secure the whole thing, and then the top and bottom halves will SLIDE apart. You'll want to be careful during this operation, not forcing anything, but you'll soon see how it all goes together. Once it's apart, you'll see the circuit plate and the contacts, most likely with discrete areas of carbon deposits where the switch has been cycled frequently. Simply scrape off the carbon from both contact elements, add a little grease perhaps (I don't add the grease because I never remember to keep any around. This usually means I'm back in there cleaning again about every year or so.), and reassemble.
It's worth keeping in mind that a great many wierd electrical problems in Saabs can be traced to similarly carboned-up switches. Lots of big bills can be avoided in this way.
Good luck!
