It's in the front, passenger-side corner of the engine compartment. As you face the engine, it's just to the left of the battery. It hangs from a mounting bracket held by one screw. I have no idea how to find the temperature switch that turns the relay on.
-update-
The fan Relay switch or sensor is located on the thermostat housing. Follow the lower radiator hose to the engine. Inside the where the hose connects to is where you will find the the thermostat, you will also find a sensor connected to this unit. It has two wires coming out and can be removed by pulling on the bracket. If you connect a paperclip or wire to both female connections (on the wire side not the sensor) you bypass the sensor and the fan will come on automatically.
The AC system on that year was actually dealer install only, Honda didn't ship any with A/C. To answer your question, yes. The cooling fan relay is located behind the passenger headlight next to the air filter box. It should be right next to the passenger side engine bay ground point.

The Honda dealership or your local auto parts store is able to get you a total car wiring diagram for a 1991 Honda CRX SI. You can also find it (for free) at the library.
There is no horn relay on a 1988 Honda CRX Si. The horn is wired to a negative terminal and sounds when the contact touch. There is no need for a relay using this type of set up.
main relay switch may need to be changed.
