Ac fan runs even when off pulling down the battery


I am not familiar with the X5, but most cars electric fans are controlled by a thermostat. If the thermostat, or the associated relay is stuck or defective, this could cause this problem. BE AWARE however that most fans stay on for a time to cool the engine, even after shut down. If your battery is weak, the fan staying on could draw the battery down.

I have a 2007 Toyota matrix and the fan that cools the motor will not shut off even when I turn the car off, this causes the battery to run down, any ideas what the problem might be


Does the fan really run until the battery goes dead?? OR are you afraid that it might run until the battery is dead?? In many cars, the fan will continue to run for a short time after you shut it off.... until the engine coolant is cooled to a certain point. It can also run for a while when you've been using your air conditioner. Now, if it is actually running continuously and won't turn off, there is a sending unit somewhere that isn't functioning correctly, either in your cooling system... or your air conditioning system. You're going to need to do some research and find out which sending unit might be the culprit..... or take it to the shop. They'll know what to do and can probably quickly fix it.

BMW 2002 X5 Battery Drain


I am having the same problem with my 2002 X5. There is a motor or fan running behind the AC control panel on the dash and if I pull fuse 48 it stops and the battery doesn't drain. Still looking for the cause and solution so that I don't have to keep pulling and installin fuse 48. BMW garage suggested that it was the Final Stage Blower Resistor. I replaced this and no change. I hope someone has an answer that will help us both.
