It's most likely the aux fan controller that is going bad. You get erratic operation of th aux fan; sometimes it doesn't start when the A/C is engaged; it may also run after ignition is switched off. A friend had a similar problem with his aux fan on an e46 (same construction) and the controller shorted out and caught on fire.
