Try jumping the green cooling fan switch with a wire and see if it turns on while the car is on, if it does then it's probably your module.

Testimonial: "G'day Robert, It's my brothers car which was supposed to be a donor car to his 79 Prelude. Long story short, his mate crashed the 79 and now it has become the donor car for the 80 model. I/we have tested the fan and fan switch (which just looks like another thermos fan) and they both work when hot wired but, don't work when normally connected to the harness. Someone has messed with the wiring and I can't find a power source to the fan (using a test light pen), The radiator Thermostat ( on the right side of the rad.) doesn't work but is by-passed. And the colour coding of the wiring on the car doesn't match the colour coding in the (Haynes) manual. This is why I'm trying to get the proper wiring diagrams so I can tract down where the fault my lay."

    Have you checked the fuse block to see if it contains a cooling fan relay?

Print the parts of a wiring diagram you need,
at a repair shop, off their data base

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.
