It burned out. Replace it. Check the fuse first.

check the relay, most probably under the hood, and check the fuse, most probably under the steering wheel near pedals. If u have two fans, most times the 2nd fan is driven by a strap from hte 1st motor, if so, check to see if its broken. If it does need a strap, should turn freely by hand since it has no motor or strap.

Yes,replace the fan clutch,don't want to get it all back together and not work cause you didn't replace fan clutch.Your water pump may have been damaged also,I hit a deer and did major damage too,had to replace water pump,the fan is connected to it.

AC Electric fan does not work(BMW 740il 1996 model)


If your ac auxilliary fan does not work while the AC is on, yet the ac cools while the car is moving, then you need to replace the ac aux fan resistors. there is a kit available for this problem and is not that expensive. the fans very rarely go bad, just the resistors usually. If your fan is turning, then it is something else. This is a common issue.

My bmw 323i overheats about after 2 hours of driving my heaters work and i dont know why.


check if thermostat is stuck open as too much flow can cause this. start car cold and see how long top radiator hose takes to heat up. shoud stay cold for 3-4 minutes.
if thats ok check thermo fan operation- run can in drive way at idle for 20 + minutes untill fan starts, keep an eye on temp guage.
