My ventilation fan has been coming on when I unlock the doors with the key fob. The first time it happened I wasn't sure it really happened. Then it happened again. it's done it 3 or 4 times over the last few months.It doesn't happen every time so I have not been able to really figure out what conditions are common when it happens, like outside temperature, or how long it has been sitting. Everything else is normal, the car starts and runs perfectly fine. I don't know if it is because I have the ventilation in manual or auto that causes it. Any body else ever experienced this?

 

New owner here too as of yesterday. From what I've read, this is normal. As soon as you unlock the door, the ventilation system kicks in to help start cooling the cabin. It's just circulating fresh air from outside as all. Particularly helpful in hot climates.

 

Thanks for replying. That's quire interesting and makes a little sense, although I don't think it will really do anything. I looked through the manual nut could find no reference to this. It's been pretty hot over the last few days and it hasn't happened again, I can't figure out what conditions are needed for the fan to come on.
