What would cause the cooling fans to stop working on a 1990 Cadillac Deville I changed the thermostat cause it was overheating now the fans don't work I can't afford to pay 80 an hour to my mechanic?

Blown fuse, bad thermal relay, bad fan motor, or bad wiring.
Try the fan relay switch if your fuse is not blown.
(second author) Another author hot wired their fan to check if fan(s) was still good.
Sounds like your fans did not move before and after you changed the thermostat (so you should have not written the word "now")? If just later, and because you may have accidentally messed with conductors when you changed the thermostat, then wiggle or clean your connections and possibly do a continuity check.
Depending on the year of the car, possibly near the battery there are a few relays (and maybe one by the fuse box inside the car or by the glove compartment). Lightly tap on them as they may be stuck. Worked for me for a stuck radiator cooling fan, as one was stuck on but that was stuck on not off as in your case so may not work the same.
