A/C Heater Fan comes on by itself
On my 2007 Elantra almost on a daily occurance while I am driving with the climate system in OFF position, all of a sudden the A/C-Heating fan turns on and blows and then a minute later or so it turns itself off again, all by itself. Also sometimes in the middle of the night the alarm goes off. It will stop if I put the key in the door and unlock the car. I didn't know that I even had an alarm in that car. No remote to lock or unlock the car or to set an alarm. Any idea what could cause that?
