Hi, I have never noticed my radiator fan kicking in on my vehicle listed above Petrol. The vehicle has A/C and this doesn't seem to start the fan either. I have tested the fan directly and it starts. I have also bridged the pins in the radiator senor but the fan does not start. What should I try next? I have also checked all the appropriate fuses I can find and they okay.

Hi,

This vehicle isn't offered in the US, but I will try my best to help.

If the fuses appear good, confirm there is power to them. Here is a link that explains how that is done:

Next, on most vehicles, there are more than one cooling fan relay. Usually they are located under the hood in the fuse / relay box. See if you can identify relays that pertain to the cooling fans. Once you located them, switch them (one at a time) with a known good relay that has the same part number. Or, here is a link that explains how to check a relay.

Start with this and let me know the results.

Take care,
Joe
