If the cooling fans do not activate in a 1997 XK8 Jaguar, first check the fuse associated with the cooling fan circuit to ensure it hasn't blown. Next, inspect the coolant temperature sensor and wiring, as a malfunctioning sensor may prevent the fans from turning on. Additionally, verify the operation of the fan relay by testing it or swapping it with a similar one. Lastly, check for any overheating issues or coolant levels, as the fans should engage when needed for engine cooling.
If you have replaced the relays in your 1997 Toyota RAV 4, the engine cooling fan may not come on when it is supposed to because of a failure in the wiring, the thermostat that sends to the fan, or the fuse for the cooling system.

Check the cooling fan relay and the control sensor. Check the fuse as well and if these are all good, check the fan motor.
Check the thermal relay for the cooling fans.

check the smog pump ,,,i had the same problem on my 95 z28
Check the temperature sensor
check see if its gitting power if it is then the motor is bad if no power check relay
Check to see if they are getting power Could be a bad temperature sensor Check to see if they come on with A/C or defroster
