Came home yesterday and pulled my car into the garage. Switched off the key and --
There came the sound of a small aircraft taxiing for take-off -- from under my car's hood.
Oh, my. Key is off, but something's definitely running. And not that old chudder-chudder dieseling I used to get in my old Chevrolet once it got warmed up.
This can't be good, thought I.
Actually, it can. Apparently the Mini, as other "modern" cars, has an auto-feature that causes the coolant fan to keep going if things are too warm, kind of like in the convection oven we have.
After a minute or two, the fan shuts off, and end of story. I dunno why yesterday would have been any different than any other day, but apparently the car must have thought so.
So, no problem -- except sometimes if a switch has gone bad, because something is apparently wired oddly in these critters, and so the little cooling fan might kick on and keep going until your battery dies. That would be bad.
Fortunately, that wasn't the case here.
