you do not have a relay for a fan belt. just change them.
The cooling fan relay switch can be located on the back of the cooling fan motor. The relay switch should be labeled as such.
by changing it.
fan control relay
All electrical circuits in a vehicle have a fuse or circuit breaker somewhere. There are possibly three in the Taurus AC circuit plus a fan relay, a fan speed control module, and a climate control computer.
The AC fan relay is primarily controlled by the vehicle's climate control system, which includes the thermostat and the engine control unit (ECU). When the temperature reaches a certain threshold or when the AC is activated, the ECU sends a signal to the relay to engage the fan. This allows the fan to operate, helping to cool the condenser and maintain optimal operating temperatures for the AC system. Additionally, some systems may have temperature sensors that provide feedback to the relay for more precise control.
The heater/AC fan has no relay just a switch. The Radiator fan relay is mounted next to the battery. It has 2 plugs and starts based on radiator temp and AC pressure.
It is the Volvo fuel injection relay . It provides the ground path for the fuel injectors. According to info I found, Volvo 1323592-1 is used as a cooling fan relay and as a noise suppression relay.
The common problem for the climate control fan not going off after the engine has stopped is the fan relay sticking. Replace the cooling relay located in the engine compartment near the fan housing. Usually if you tap it with a hammer it will go off. This is the fort sign its the relay sticking.

In a 1993 Volvo 940, the fan relay is typically located in the engine compartment, near the fuse box. It is usually mounted on the driver's side, close to the battery. For precise identification, you may refer to the vehicle's manual, which provides a diagram of the relay and fuse layout.
