I was rolling down a window when all of a sudden the follow 4 things STOPPED WORKING and haven't worked since: - All power windows - Heater blower - Horn - Wipers All of the relays I've found seem in tact and the fuses are fine. I've even tried replacing the ignition switch module per another Saab owner's advice. Does anybody know what could be wrong?

Not a convertible.

Yes, the part under the lock cylinder... with the pins/contacts coming out of it - I swapped it with one from a 99 9-3 parts car we have... as the part numbers were the same, interchangeable. The one I used, had some water in it, which I cleaned out.... but I took it apart, and metered it all out... everything SEEMED fine... and everything works in my car except for the above mentioned items - so it seems like it's NOT the ignition switch module.

Relays under the hood are all working and fuses... haven't checked for power at each one of them yet... but the problem HAS TO be BEFORE the fuses somewhere to affect so many different things - I just checked to ensure the fuses weren't blown.

Electrical issues are like math. You get the right answer when you follow the correct procedure. SEEMS is not a definitive answer. Installing a used switch that had water in it, SEEMS like a horrible way to guess, considering the labor involved.
How can you know if a relay is working without checking for power transmission through the relay with the design load in place? I suggest you pay a mechanic to fix this car, because it is not going to fix itself. Electrical issues are like math. You get the right answer when you follow the correct procedure.
