Hi all,

 

I have a Skoda Fabia estate Mk1 2007. I parked it up last night and the fan was running at what seemed like high speed and wouldn't switch off. I eventually disconnected the battery. Going off other threads it seems like the radiator control module relay is the likely suspect. Before I order a new one and attempt to change could this issue be fuse related?

 

I doubt it would be anything else, unless the car doesn't have aircon, in which case I'd suspect the radiator thermoswitch.

What price is a new fan module? I would say that they're usually pretty reliable, so consider 2nd hand unless new is very reasonable.

If it starts up again when you reconnect the battery, you could try undoing the wire end of strip fuse 3 above the battery and lifting the crimp/wire clear away to stop it.

May well be worth checking the low speed function, easy if the car has A/C, just switch that on, set it to cool and wait a short time.  (Different fuse does the low speed, blade fuse no.8 over to the right of the strip fuses, under a removable cover.)

Excellent advice thankyou! I've removed strip fuse 3 as suggested and the fan has turned off. I tested the low speed function by turning on the AC as suggested and this is still working. I'll look for a control module and replace and see how it does

Will this low speed function turn on and cool the engine if needed without the AC on? Just wondering if I need to worry about overheating if I need to drive anywhere in the meantime.

Yep, as long as the radiator thermoswitch is OK, but on A/C cars it's very lightly loaded as it only carries the relay coil currents for the control module, rather than the much higher currents that the fan uses.
