amongst many of the problems i have with my 318ci, i tend to keep getting flat battery.
what i have noticed is, when i park car up, remove key and check i have everything before i get out of my car, i noticed that the blowers are still running on the car.
i can return to the car an hour later, and blowers are still on, not full speed, but definitely blowing air out still.
i have changed the relay to the blowers as i thought it may be sticking, but after a few weeks it still does it, so possible relay has gone again or it could be something else.
to stop me getting a flat battery, i remove the 40amp fuse each night (if i remember).
has anyone else seen this or had this, and any ideas for a permanent fix.
other than this, the heater works fine during driving, air con works fine, so speed surges in blower speeds.
thanks in advance.
