Thanks for the tips. I was able to take a look at it yesterday when I got home from work. All I did was to jiggle the wires to the blower, and then it started blowing! If only other things were that easy.

It is a manual climate control. I think it might be some kind of short in the wire.

I have a 1993 940 wagon w/ 150,000 miles. The AC fan doesn't always blow. Sometimes it works and sometimes it doesn't. Any help with this problem would be greatly appreciated!
