Hi,

So for some reason or another my cooling fan won't turn off when I turn off the engine & ignition. And it's not just a couple of minutes. The first time it stayed on I noticed after about half an hour. I can unplug either of the two plugs that directly connect to the fan and it is then off. Bit embarrasing when you have to pop the bonnet every time you leave the car unless you enjoy push starting.

After reading a few posts on here people have issues with the fan not turning on and replace the temp sensor. Is this likely to be the same solution for me?

I have looked for this for a long time and have found nothing relevant to a fan that keeps running.

Thanks for any help. If need be I will install a switch that can manually override the fan inside the car but thats a last resort

Cheers

I think there is a relay under the dash which should keep the fan turning to cool the residual heat after a run [if the fan was 'on' in the first instance].

I had a new 'lower temp' fan switch from Jorily a year or two ago.....it is now just starting to play up, by not turning on when it should.....[a quick short-out with a paperclip jarrs it into life for a while....] As I am too tight-fisted to buy another from Jorily..and certainly too tight-fisted to buy a VAG item, I shall look for a long piece of wire [two,actually], piggy-backed off the fan connectors at the switch....run it through to the inside of the car, and fit one of my many surplus switches....then, if the rad switch misbehaves, a quick flip of the switch [on and off may suffice] will restore things.....or bypass things as necessary.

Success! Thanks for the post.

I just unplugged every relay one by one then plugged in the fan again and it was still running. Started the car dunno why but turned the ac on and off a few times and the fan turned off. Turned off the car... fan still off.... for ten seconds then turned on again. Followed the same procedure and its now been off over 5 minutes. I just hope it stays this way now.

I used to have an old rover SD1 that would overheat. I disconnected the fan from everything and rewired it only to a switch. It seemed to work pretty well. Turn it on when the engine looked to hot turn it off when it was too cool. Saying that the ignition was bust so I wired in an ignition on/off switch and a starter button. That worked well too

thanks again. We will see if it lasts
