Hi guys.....firstly i want to say i've searched the forum but not found anyone having had quite the same issue..

Basically my driver side fan has started coming on the whole time when the engine is on regardless of engine temp...the fan appears to be on high speed all the time. I have looked and the passenger side fan isn't spinning at all. I have a 97' phase 2 gti 6 with air con (doesn't work). I have removed the 2 green relays at the front and cleaned them up (they looked fine with no water/dampness)... when the drivers side one is out the fan doesnt come on at all, but as soon as i put it in it comes on again....I've switched the relays round and the same happens.
Now i dont know if its a problem with the relays or something to do with the other fan not spinning, or if its the Bitron unit (believe in passenger wheel arch) which i haven't checked yet..
I have checked the fuses by the battery and these are fine.
Can anyone suggest what this is likely to be please as i'm getting cold and wet trying to go through everything, so want to eliminate the most likely first....
Thanks in advance guys as i always get a good response on here...

I disconnected the brown plug and cleaned it and put back but made no difference.....maybe i need to clean it better...Is this the brown plug thats in a row of 3 to the right of the engine block??? i think its connected to the coolant housing/hose attached to the block????

Sorry for blowing the dust of this topic, but when my 6'er was picked up for the repaint, I noticed that both fans were on high speed when the engine was started.

Will this be a corroded brown plug issue, or a bitron issue?

And what if I just let them run on high speed? Cannot do any damage, can it? Better than not running at all.

Thanks for the quick response.

I will have a look at it when my car returns. We have a "Peugeot GTI wizzard" in the Netherlands, I will ask him to have a look at it as well. He knows my car for a longer time than I do
