Fan on inside of X5 draining battery
 

Hello,

Has anyone heard or have had a problem with a fan coming on with the climate control fans off?
I have a fan that has stayed on after getting out of the x5 and the next morning my battery was dead. When I turn on the climate control it sometimes sounds really loud or it turns off and the climate control fans kick in. I can't figure it out.

Any help would be greatly appreciated and alot of dealer headache money saved.;)
