Tazman861 Report post Posted May 4, 2019 Hi all My electric fan has stopped working, I’ve checked that I’ve got voltage at the fan plug on the top of the fan and I’ve put 12v to the fan and it spins easily so I reckon the control box on the fan has failed Is there anyone who can repair these (I know BMW doesn’t sell it separately) I’d rather not have to buy a complete new fan unit but I can’t see any other choice unless anyone knows differently??

B.Merr Report post Posted May 6, 2019 I had the same predicament a year or so ago. Seems the control unit, which is exposed to the elements and corrodes, can't be purchased on it's own. I bought a quality replacement fan unit for £165. On the plus side, it's a five minute job to swap new for old. I guess there's a possibility the control unit can be carefully opened, cleaned up and some soldering performed to repair - I don't own a soldering iron so this option was closed to me. There is an option in INPA to test the electric fan in isolation, which is handy. Quote Share this post Link to post Share on other sites

momo Report post Posted May 7, 2019 Seems as though it's not much more to just get a replacement fan unit.. Quote Share this post Link to post Share on other sites
Tazman861 Report post Posted May 7, 2019 I’ve just ordered a Hella replacement for £112, I’ve also seen on YouTube someone who opened up the control box and replaced a capacitor and something else so I may look at repairing my old one?

Tazman861 Report post Posted May 7, 2019 Not to mention that my fan has a black control box and that silver one isn’t a direct replacement but I don’t know why?? There seem to be loads of sup-receded fan units if you look on real oem Sent from my iPhone using Tapatalk Quote Share this post Link to post Share on other sites
