Cooling fan stays on long after the car is off...
Hey everyone,
I have an 04 MCS and after a relatively long drive the fan doesnt quit for a while after i turn the car off. It goes on a lot when it is idling, too. Any speculation as to if there is something wrong? Other MINIs dont sound like that., that ive heard at least.
Thanks,
Marco

Hi - didn't want to start a new thread because I figured this is where my question would probably be directed.
Anyhoo, on Monday, I noticed that my 02 MCS's fan still had not shut off after a normal day of driving. (BTW - I drive back and forth on the beltway 5 days a week and deal with moderate to heavy traffic, if that can be taken into consideration.) However, I assumed that it would shut off after a while. It had done that before, where the fan would last for what seemed like forever and then eventually shut off. When I got in my car about an hour later (the fan was no longer running so, I assumed that everything was fine) the car would not start at all. We tried jumpstarting and turned out that the battery had 29 watts left out of 550 watts; so I ended up buying a new one. To make this a shorter story, I now have to disconnect and reconnect the battery in order for the fan to shut off and not drain the battery.
What does it all mean? Am I going to need a new assembly like you all stated here? Help, please.

See this thread for fan stays on issues:

If ???? you can take apart the fan by seperating the shrouds ...RELAY, MAKE CONTACT, WHITE GREEN161360141229 is the part to replace. Otherwise it is included in the entire fan assembly.
Find the correct plug and you can turn the fan off without disconnecting the battery every time ..... until you get it repaired.

Thanks Speedwing.
I followed the link and several other links that gave a lot of useful information.
But, get this. Yesterday, after reconnecting the battery when I left work (mind you, it had been sitting for about 8 hrs) I drove in pretty heavy, stop-and-go traffic for about 1 1/2 hrs and when I got to my destination, the fan stopped. But, with my luck and being the worry-wort that I am, I disconnected the battery anyway.
I got home later and decided to give it a try and not disconnect the battery; this morning it started fine.
How weird is that!

I've been through this a couple times and yet to replace anything. I replaced the battery a few weeks prior to the first instance. It just seems that after a couple days the fan switches correctly again. I disconnected the battery just to see if letting the system reset after a few hours of no power will again get it back to working correctly. We'll see in the morning.
I've also considered installing a kill switch to make turning off the fan convenient. At least until I can get to replacing the fan motor.

I have an 03 MCS, and my fan comes on. This is normal when the thermostat hits a certain temperature, the coolant fan will come on. It's no big secret. But it shouldn't stay on for an extended peiod of time, to where the battery drains excessively. My fan kicks on, and runs for about three minutes or so, then shuts off. The next time, it does its thing, I will check my coolant level. I beleive a low coolant level will cause this, because the engine is running a little hot at that point. But my temperature gauge, registers normal and that's weird. I know about cars, and if a coolant fans runs, then your temp gauge should register it. But hey mini's have alot of quarks.....Just my two cents.

Yuille36, also remember the cooling fan reacts to the A/C system pressure, not just on coolant temperature. When it runs excessively, like more than a few minutes after turning off the vehicle, the system is broke and needs fixed. As it starts to fail, it can be a intermittent problem at first, but it will eventually fail for good. Three minutes is not really excessive, but more like normal dependent upon the conditions.

Hey guys mine is kinda doing the same thing with a few more quirks. I have an 2006 Mini that when i take it for a short drive then park it and keep it running the fan will go nuts and the reservoir for the radiator fluid will have about an extra 2 cups of fluid in it. So i figured it was a stuck thermostat. So i changed that out but it still does it. Mind you I have never let it get low on radiator fluid. Also when the car is in park and running after going for a drive the fan is NOT on. When the fan does turn on there is a loud chugging sound (the back flush of the fluid into the reservoir) and then the fan kicks on full blast. My temp gauge never leaves the middle point and the fan stops after about 3 minutes. I'm stumped....
