Can i change the fan motor on my bmw 316i air

Yes you can but its located on the engine side or you can get access through the dashboard or engine bay which ever looks easier its buried in there you must do alot of parts removing till you get to it almost entire removal of the dashboard to get to it. And if you do make sure you take alot of pictures as your taking apart so you can remember how to put it back together

yes the fan motor can be changed and this can be done by the firewall.
