FSR fixed. Thanks Heising
Thanks Heising, Your DIY worked like a charm and the FSR is working again (2002 4.4 X5). Its one part that had a slow death. Didnt realise that my Fan could work this fast.

Just did mine last week. It was only a corroded Connector. Quick clean up and it now works great!

Thanks Heising! Air Conditioner blower fan fixed! X5 E53
Yesterday I called the dealer and asked how much the factory Final Stage Unit was for my 2003 X5, and they said $144.
At that price, I figured, what have I got to loose in attempting repair of my FSU like you described? A little digging of the potting material, some soldering and an hour and a half later my AC - heater fan is working great again ! Thanks, Heising, for the fix and the pics, they really helped make it easy! $0.00 is real nice! I posted this just to let googlers know that this fix is current and for real. Pay the .25 cents to get on board at Xoutpost here and get in on the action! Fish ON!! -----------<')))>< |

When I bought my used X from Sanford Acura in Florida a few yrs ago, it had the intermittent fan issue, told them the fan replacement job was a huge job that costs almost $1000 at a BMW dealer (knew it was FSR), they came down $1800 on asking price. It was the FSR, cash in pocket.

It PAYS to read these forums!
Smart move TiAGx5! I'll keep that in mind as I shop for my next Bimmer! Looking for an older used 330i with sport pkg and manual transmission. May be a fun daily driver with not quite as bad a gas mileage as my X5!

I'd like to chime in that this free fix only worked for 2 years. I posted back in 2010 that it fixed my intermittent fan speed oscillation. Then, in late 2012, the FSR completely went out and there was no fan at all. Still a great fix, and if the new FSR has the same symptoms, I'll be soldering that one too.

Hi guys. Glad you all are benefiting from this easy fix! The longevity of the fix will depend a lot on the re-soldering quality. The semiconductors get really hot, and the legs will re-open again if not soldered carefully. One good solution to add life to any FSR is to have the blower running "halfway up" or more. The FSR block is cooled by air running over it, when your climate control fan speed is slow, the FSR block will tend to get hot.
If you want to use a solder with a higher melting point (Silver Solder) that's OK too. Lead free has a higher melting point also, but a little tougher to flow. |

I wish I knew about this thread earlier. Well, it's bookmarked now.
