Fuse? Resistor pack?

If you take the casing off around the fans and they are running freely i would consider cleaning or replacing the resistor pack”¦.

Can't seem to find it in the wiki

Re, the wiki article: It is almost ALWAYS the motor that is the problem, even if just replacing the resistor pack appears to cure the problem. BMW specify their parts to a somewhat higher standard than the likes of Vauxhall with their Zafira, and the resistor pack is unlikely to fail unless its overloaded by a motor drawing more current than it should, combined with less airflow past the resistor.
Once the motor is out and turning relatively freely, it needs to be connected up to a battery and repeatedly run and lubricated while holding the motor in your hand with the shaft vertically. WD40 is OK for initially freeing up a badly seized motor, but it is not suitable as a long term lubricant for the job. For that, you need a light lubricating oil, such as "3 in 1".
It takes a bit of time and effort to work the fresh oil right into the bearings, but you will be rewarded by a motor that will work for another 20+ years.
The motor has carbon brushes, which do wear away, but I've never seen a pair that don't have a least half their length remaining.

This worked a treat for me (combined with resoldering the blown resister), it gets messy running a motor whilst adding wd / oil, I put mine vertically in a vice and shrouded with a card board box whilst it was runningBrianmoooore wrote: it needs to be connected up to a battery and repeatedly run and lubricated while holding the motor in your hand with the shaft vertically.

It only takes a couple of drops at a time, placed above the bearings (shaft vertical) with the motor stopped. Next move the shaft up and down a bit to the limits of the end play, before powering up. Repeat several times, turning the motor the other way up.
Don't get oil on the commutator and carbon brushes.
