On my 99 Deville I got the service light last week, code is p1660, cooling fan issue. Pulled the fans and they took 12 volts and spun like champs.

So, is one or some of the relays dead? If one is dead, should I just replace all three? Are they the same?

It sur eis hot, and I'd like to enjoy the AC again....

If it ain't broke, don't fix it. Just replace the bad relay. I would think that they are all the same. Try tapping them with a screwdriver handle. Maybe it just got stuck.
