Fan blower comes on while ignition switch off
 

Good day to all... Just needed some advice/information. I have a 07 Hummer H3 and we were detailing the inside and I heard the fan comes one for about 5 to 7 seconds. I am trying to let the inside of the vehicle dry and left my window open. I can still hear the fan comes on once in a while. Is that normal or should I be concern?

Thank you and looking forward to all the replies...:)

You could be hearing the electric motor that is part of the brakings system. It will run if the ignition is on. Double check to make sure your ignition is off. Sometimes just the weight of a key ring can make the ignition switch move that 1 click clockwise. It has happend to me before. Just a thought.

Thank you for the reply. Actually it could not been that since the ignition switch is all the way off and the key is not inserted. Should I be concern now?:(

That's a new one. I would keep a lookout for other strange things happening.

My blower does same thing, Help?
 

My blower stays on all night and drains my battery if I don't pull the fuse every night. Did you find a solution? Please help if you can. Thanks
