Subject: Re: radiator fan always on please help!

The radiator fan is controlled by a thermostatic switch near the bottom o f the radiator and is not wired over the ignition, so will often come on just after you have stopped the engine as heat soak puts the switch over its limit. However, it should switch off again after say 5 or 10 minutes at most (depending on how hot it is, of course). If it is running all the time, I would this switch first - it is not expensive and easy to change. They cost about 80 kroner here in Norway, which is about 10 USD. If you have air con then the radiator fan is also turned on by switching the a/c on, via a relay behind the fuse box. My 9000T has ACC and I had a similar problem that took some time to solve. The relay was sticking closed so if the a/c caused the the relay to close, then it stayed closed even after the engine was stopped leaving the fan running for ever after I stopped the car. I thought this was due to the radiator switch, but changing the relay eventually cured it. Jeremy Massey
