Congrats on the car. I've always admired the styling of the last US delivery Spiders.
Could be a fuse or a relay gone bad.
Now that you are a new owner, peruse the owner's manual for a list and diagram for fuses around the car. Never hurts to read the owners manual, lol. I read through the ones for my Alfas about once a year, always finding something new it seems.
Also, owners of Alfas found that doing a general Google search can give you the information you may need. Many BB posts are easily found in such a search. Try "1994 Alfa Spider fan fuse" to see pictures/diagrams of the fuse arrangements, and discussion posts on the subject.
I'm sure owners of these spiders will help you. The above is just a general comment to get you started poking around in your new car, something you will have to do anyway if you want to keep the car up. Not a Toyota Camry, lol.
Have fun.
