Question about 1990 Acura Legend
This question got duplicated several times for some reason.
You would check the fan relay to see if the temp sensor is grounding it, if the relay is hanging on, or if you have a short in the wiring.
The blue wire goes from the temp switch to the fan relay and the fan control module.

If you can locate the temperature switch, looks like a large bolt head with 2 wires on it, bridge the wires on it, and this should make the fan work. If the fan works then this switch is faulty. If the fan doesn't then it could be the fuse, or a broken wire.
The fan switch is either on the radiator or on the thermostat housing.
If you can get to it easy, short across with a screwdriver.

This could happen if your fan is indeed weak. To test disconnect the thermostat of the radiator by removing the terminals near the radiator hose towards the engine. You should see the fan run at its highest speed, then you can check if your fan has weakened.
