their are 3 relays associated with the a/c all three are under the hood about top center of the firewall right above the distributer cap
The relay on the passenger side firewall is the ac compressor relay.
The AC compressor relay is located under the hood, on the firewall, passenger side.
In a 1997 Cadillac Eldorado, the AC relay switch is typically located in the underhood fuse and relay center. This panel is usually found near the battery, on the driver's side of the engine compartment. To identify the specific relay for the AC system, refer to the diagram on the cover of the fuse box, which will detail the functions of each relay and fuse.
