Cooling fan will not quit

Anyone have suggestions for me to check why the electric cooling fan will not turn off ever. It ran my battery dead this afternoon when my motor was off. Only way I could stop it was to disconnect the battery. '03 Justa Cooper.

There's a fuse you can pull too....

The problem is the relay is stuck, you need a new one....on your year it may be mounted on the fan assy itself, however don't confuse it with the resister pack. It's a small box with 4 or 5 prongs, it just unplugs.

Left battery disconnected overnight and car ran properly today. Hope it just re-set something and continues to work.

The fan relay is sticking, it's not an expensive part and it will probably do it again.

Next time it does, try bumping the fan housing area with your fist, if it stops it's clearly the relay.

Or just buy a relay at the auto parts store, it's a common relay, nothing exotic about it at all.

Knock on wood, it has not done it again so I have not replaced the relay. :D
