It is fairly tricky to get to. You must remove the passenger's side and driver's side footwells and then remove the wiper blades, cover, wiper motor, and cover form the blower motor.
Here's how to get to the blower motor: http://photo.platonoff.com/Auto/2006..._Motor_Repair/ (NOTE: you do not need to remove the blower motor) Take a look at picture 6 in this DIY and it's the wiring which plugs into the fan and goes through rubber grommets on each side. One side travels to the passenger side and plugs in while the other side travels to the driver's side and has some cooling fins.
Here's a picture of what it looks like: http://cgi.ebay.com/ebaymotors/Saab-...8#ht_573wt_939
You can see the cooling fins in the center, the red wires going to a plug (which plugs into the fan) and another plug.

Hope this helps.
Good luck.

-remove wipers
-remove cowl
-remove fan cover
-remove cabin fan

-open the 2 wing doors that control recirculated flow and reach your hand through the one on the left to unclip the two connectors at the left end of the resistor loom
remove the access cover below the dash on the driver's side (US)

-lay on your back with your head under the dash and your legs hanging out the door with the door jam in the middle of your back and painstakingly reach up with a 1/4" open end wrench or socket with the proper size extension and remove the 3 screws that secure the resistor into the side of the airbox (this will take some patience)
when you have it released, depress the accelerator all the way with one hand and wiggle the resistor out of it's home

-pull the remaining wire loom through and out (or as I did just cut at the resistor, you are going to throw it away anyway)
re-install everything in reverse order

-Why you are going to hate this job:
Your hands will feel like they went across a cheese grater when you are done because you have forced them into a number of sharp, plastic holes
removing and replacing the 3 screws that hold the resistor in will seem impossible and you will be in considerable pain the next day from laying your back across the door jamb
re-connecting the 2 wire connectors through the left wing door will also seem impossible, and just when you are ready to give up they will click together

-Pitfalls to avoid:

Do not reconnect the two electrical connectors until you have fully mounted the new resistor. The metal fins of the resistor have power running through them and will startle you when touch it to something metal and sparks shoot everywhere
Be extremely careful when removing/replacing the fan. the plastic blades are very fragile. If you break them you can find used fans at www.car-parts.com for $35 including shipping. Don't ask why I know.

I ended up pulling the blower motor and put 12v to it, no movement.

So soldered in the new brushes and cleaned the commutator with emery board and now she blows like a bat out of hell.
