    2001 Radiator Fans not working

    Looong time forum cruiser, first time post. Thanks to all for the great info on this forum!

    2001 CRV - Both radiator fans have stopped working. Does anyone know what sensor(s) or relay(s) controls them, where it's located, and how to test?

    I can't help too much other than to ask if you have tried turning the A/C on. That should trigger both fans.

    Check the under hood fuse box. I believe there is a 20amp fuse in there and I believe it also contains the fan relay. This fuse protects the fan motors.
    In the under the dash fuse box, I believe there is a 7.5amp fuse that protects the fan relay.
    The radiator fan switch in located somewhere behind the valve cover and more on the passenger side and it is on the thermostat housing, I believe. You will have to research this further on the Internet.
    I think once you locate the radiator fan switch, you could just jumper the two wires going to it to see if the fan(s) go on when the ignition switch is ON.
    If the fan(s) now go on, I would assume the switch is bad. I suppose you could remove it and suspend it in hot water and the two terminals should show closed (continuity) just before the water starts boiling.
    Just guessing in general. overall.

    I totally agree on the A/C switch, it's the first step in checking the radiator fans. If they come on with the A/C, it's not in the fuses. If they do not come on with the A/C turned on, then it's probably in the relay/fuses route.

    Checking relays is pretty simple, turn on and listen for click. Sometimes they will click and still not make contact, but it's more common for them to fail in the switch (coil) and do nothing at all. Or find one that is the same part number in the panel (and non-critical) and swap them for testing.
