Question about 1995 Cadillac Eldorado
There are 2 fuses for the cooling fans both under the hood 50 amp in thr rh maxi fuse block the other one is in the engine compartment a 10 amp there are 3 relays that control the fans. the relays are either located in the left foward part of the engine compartment or on the bottom of the radiator to identify the relays i would have the fans running and disconnect to see the cooling fans are controlled by the pcm. the pcm gets temp input from the coolant sensor all three will be located together.

223 is not that high, my fans kick on at 218, and run just in stop and go traffic, they shut off when you get back to cruising. The temp gauge switch is located in a bunch of different places, I would look first at the bottom hose on the engine, then look on the radiator itself for the switch. If you can find it, you can but the new one preset qt different temps. the parts store will help you find it if It isn't where I thought. If I was you, I would be looking at the coolant. They have little testers but I think they are only for freezing, but they would tell you how much coolant to water you have. it should be 50/50. Or something like that. Check it out, hope this helps.
