The blower motor is actually controlled by a readily accessible 'Hedgehog resistor' by reaching up just behind the dash.
Although called a resistor, it looks like it's actually a voltage regulator with various preset voltages to control the different speeds - and it is quite common for it to fail either on just a couple of speeds or all of them. SEE THIS THREAD
... and its called a hedgehog resistor because of its 'spiny' heatsink
It could of course be something entirely different causing the fault, but this is the easiest to change
{other than if it's just a blown fuse}
Do you know how to figure out which blower motor it is? There are 2 types there are ones with 2 wires and then one with 3 wires. I don't want to buy the wrong one and waste a bunch of money on it. I took the cabin air filter out and tried to check it that way but no way of reaching the back of the motor. any suggestions?
My a/c and heater will not blow any air. It started with the A/C cutting in and out while it was on. Any ideas? which fuse is it(in the engine fuse box, F46 30A)?

Looks like it could be FL1 - 50A which controls AC, however, as you state that fault started by intermittantly cutting in & out, then its probably not the fuse unless its working loose from its holder
fixed my MINI Cooper S R56 fan blower not working in 5 min !!!!
Hi,
I just had the same issue and fixed it in 5 minutes... these are the steps :
- Contact key out
- remove the side panel on the driver foot side, 2 x to 20 screws.
- unplugged the fan motor resistor
- start motor, an error message appears and disappears
- switch engine off and remove contact key
- put switch back on place, start motor, all working as before.
I had the car out in the cold for 2 weeks and battery level went low, so I suppose the electronic went into strike mode, and was put back in normal mode after the “reset “.
I had a similar issue and resolved it same way on my x5 4.8i, as MINI is also a BMW, I thought the trick might work too, it did... probably saved lots of $$ from official dealer this time, their goal being to sell parts and hours but not helping customers in their best interests ;-) I know what I am talking about...
Thank you Forum !!!!

I’m having similar issues with my R58. It started last winter with the blowers not working on cold mornings. All through summer no problems.
started getting cold again and it’s playing up.
No blowers for first 10 mins of any drive then it all starts working again.
I have replaced the hedgehog (voltage regulator/ resistor) but still no joy.
BMW are suggesting the fan motor but this doesn’t make sense as it works when it is warm.
any ideas?

HI, i have no idea about cars. I bought a heat resistor but took the hedgehog resistor out and put it back in - its worked for a day then stopped again.
Did you change the resistor with the green band on it or the hedgehog one?
if it was the green, did you follow a video? can't seem to find any
TIA
