    Heater fan

    Hi guys is there any way to check a heater fan works without it being on the car???
    as I have just removed mine which didn't work and would like to test it to see if it was that or the wiring??

    Just connect it up to a 12v battery but watch it doesn't have all your fingers off in the process!

    Turn your right hand, containing the fan. If it turns, it works

    Multi directional.

    It doesn't matter which way you connect it, the fan will turn either one way or the other.

    so cleaned them up but it still plays up,thinking it could be dash controls,
    i got a spare fan though,tbh im not to bothered cos summer is comin!!!

    Re: Heater fan

    The resistor thingy controls the speed .It reduces the voltage to the fan so if that is there then it should work

    guess thats located at dash end then?,so your saying that if an
    alternative fan was connected up it possibly should work?

    Re: Heater fan

    The resisters are in the fan housing and not at the dash end. You could get some resisters from Maplins and experiment. It's pretty simple stuff. If you've got a multimeter you can even measure the resistance of the originals and buy something similar?

    I've got a fan housing in the garage if you want a few pics?

    thanks woz,interesting,so in relation to the male connectors i think in the
    fan housing where are the resistors located?

    Re: Heater fan

    It's actually just one big coil spring type resister and the male connectors join it at different points for different resistances. It's located directly behind the male connectors in the housing.

    Re: Heater fan

    I know for some cars you can just buy a resistor pack if the thing goes screwed .... is this not the case for the R5 ????

    How would you get access to the resisitors ..... thru the inside of the car and by taking all the dash out ?????

    Might be a daft question, but have you checked the fuse?

    you need to find the cause of the problem first, either switch or wiring.
