I have a 98 Caddy Deville About a month ago the air stopped blowing Just stopped Once or twice it came back on and worked perfectly but about two weeks ago it stopped all together Why?

It sounds like there is wires that have a loose connection somewhere. I have a 79 DeVille and the Blower Motor was OK but at the Climate Control Switch that controls the Air/Heat/Fan Speed a loose connection where the wires fit on the Control Switch was loose and a defective Climate Control Switch was the problem on another 79 DeVille. I know there are years between our Cars but this might help you as a Dealership can be expensive. Helminc.com also makes Service Manuals for many makes and models and the Service Manuals are just like the ones at a Dealership. They are a little expensive but worth the investment if you plan to keep your Auto.

Air not wooking on a 1997 deville Cadillac?

Assuming that the a/c was in good shape before it suddenly stopped working, the problem is probably the blower motor. As it turns out, this is very common. Try searching answered questions under "blower motor 1997 Cadillac Deville" I just had to change mine in a 1996 Deville. Motor aprox. $240.00/Labor aprox. $100.
