Heat/ac fan turning on when car is off and locked.
I have a really serious problem where my hvac fan is turning on at full blast on it’s own. I would turn the fan knob all the way to off, turn the car off, close and lock the door, and if I come back like half an hour later or so, theres a chance the fan will be running.
And the only way to turn it off is to turn the key on and off a few times, as turning the fan knob to high then back to off does nothing. However, when the car is running, I have no problem with it, it works as it should.
I need a solution to this real fast because it could come on at night, and run the battery down, and then in the morning when I leave for work boom dead car.
TL;DR: Hvac fan is turning on by itself, need a fix.
