Hi Guys,

I have a 99 rover mini cooper 1.3i, quite recently it had an issue
starting which eventually turned out to be a relay box which needed
replacing. Around this time the radiator fan seemed to be on constantly.
Also when stopping at lights for example the revs seem to dip and it is
as if the car will stall. The rev fault in particular seems to only kick
in after you have been driving for about 10 minutes or so.

I took it into a local garage who could not find any problems and
cleaned out the valves in the injection system. The radiator fan now
does not come on all the time but does come on when driving. Over the
weekend I it noticed it coming on then turning off again. but now it
seems once it is on it stays on until the engine has been switched off
for a few hours. Could this be a faulty temp sensor or something along
those lines? or an ECU issue? I know the weather is really warm at the
moment but I don't think the fan should be coming on all the time unless
stuck in traffic and not moving on a hot day.

Any advice would be great,

Cheers,

Neil.
