Përshëndetje Fluturim,


Change the cooling fan relay and let us know if that works. A cooling fan relay may stick and cause the problem you describe.

It's normal for some vehicles to have a fan run for a few minutes after the car is shut off. The reason the cooling fan continue running is to help the engine to cool. Your vehicle still in active regeneration will be initiated every 300 miles or so depending on how you use your car and will take 5 to 10 minutes to complete. But it's a problem if your journey's to short and the regeneration doesn't finish. During active regeneration you may notice cooling fans running. Kindly monitored and let's us know if the cooling fans running more than 10 minutes.

Hey, My condensor kicks in from time to time but no rad fans whatsoever! it is suggested it's a resistor or sensor within the fans that's at fault which could be as simple as replacing that part or as bad as replacing the whole fan set up.

By condenser, I think you mean compressor. Condensers don't kick in, they're just for heat transfer. If you radiator fan isn't working, you should check for power at the connector in each speed (if applicable). You could run a jumper wire from battery positive to confirm that there's an issue within the fan assembly itself. 

In regards to the cooling fan staying on after the engine is shut off, I don't think the relay would be an issue. I would assume that even if the control side of the relay were completed, power should be controlled to that fan on an ignition based circuit, which means 12v should not be present. I would get a wiring schematic to confirm.
