Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.
The blower motor resistor is an electronic module type. That would be the first thing I would check or replace that will make the fan stay on high all the time.
To Install :
I am not sure what the resistor would look like and exactly where its located. Maybe you could point it out to me on the pictures that I took of the car under the hood and vent cover. Problem is I don't know how to attach the pics to this reply or how to get them to you.
Also, how would you check the resistor for a fault? What would indicate its OK or bad?
The part numbers you are quoting, are they SAAB's or generic or ??
I put 2 photos in photobucket dot com as you suggested. Never used that site before. Hope it works OK

Well I got the fan control out of the housing. Your pictures of its ass'y in the housing helped a great deal as the lower screw is quite hidden from view.
Now the question is how do you know its faulty?
Is there some way of checking it before ordering and buying another?
I'm sure the one dealer here won't have the part in stock ( he carries next to nothing for SAAB) and if I order it I'm stuck with it.
My one and only dealer here doesn't stock any parts and I don't have any confidence in ordering any from him as its a long process and usually turns out to be the wrong part.
Do you have any places in mind where I can buy the part for $91 approx.?
