Finding Final Stage (Hedgehog) Resistor

My Mini Coopers auto climate control has been playing up for months now. The heater and air conditioning works however the fan speed doesn't increase to blow the air into the car.
Having doing a lot of research and speaking to a Mini mechanic I know the final stage resistor is at fault and I now have a replacement. However, I cannot find its location in my car. I've watched a video on someone replacing one and seen a couple photographed step-by-step instructions, but I just can't find it.
If anyone can help I'd be very grateful.

Had mine replaced a couple of weeks ago when the fan lost the 1st 2 speeds.
Although It was done by the mechanics at MiniMatt, I was watching where they went as I was confused of its location myself.
So, Drivers side footwell - reach up almost to dash height behind the 'central heating unit block' & its attached by a torx screw somewhere around there.
There seems to be a couple of designs of them, although its called a resistor, the components looked as though they were part of a variable stabilised voltage setup unit.
Sorry for being a tad vague but at least you know the roundabout region to have a feel around now

Thank you both for ypur replies, I came across instruction once that showed it in the footwell about level with the climate control, but all i have there is one plug of wires for something else. Will try and look up where Restyle said and see if i have any luck (Hopefully!!)

Do you mean youve had no luck finding the 'resistor', or that you fou found it but it wasnt at fault?
If the former, why not try reaching under the dash with camera & take a picture of the area to the side of the central speedo on drivers side, & we'll try & point out the 'resistor' holding screw.

I cannot locate it. I've looked in the footwell to the left where they normally are and i have a blank bit of plastic and not a space where it should slot in.
I've also heard of it being in the glove compartment, mine is not.
I will try and get a photo ASAP as its getting incredibly annoying with the car steaming up, and having no air come in the car unless its moving.
Thanks for your reply.

Pictures

I've managed to get some pictures from the drivers footwell. The first is the left side and the second is of the right. On the second you can see the gap where normally the hedgehog would be connected.
I really appreciate any help with the issue.

Ive just had a look on REALOEM at the resistors location, & it would appear that you are correct in that your 2nd picture shows where the resistor used to be.
So, during sometime in the cars lifetime, we can assume that the resistor failed - & it was looked at, but not replaced.
So all youve got to do now is go to your local freindly MINI dealer armed with the part number shown in the diagram & ask them nicely to fit it for you.
Ta Dah!!

Thank you so much for looking. I bought he resistor months ago thinking it would be a simple replacement.
Looks like I'll need the wiring installed to connect it up.

I'll prepare my wallet......

Cant see any reason why anyone would permanently remove its connector, I would assume its just been tucked out of the way.
Id just give a gentle tug to any cables you can see or feel in the area, & hope that the 'missing one' with a connector comes loose.

Now i've seen this wiring diagram, I think the wiring next to the empty resistor hole is a bodge job. Haven't seen that wiring that i've pictured on any other mini. And somehow whoever had the car before me has wired this up in place of the resistor??

Just remembered I had the Haynes manual gathering dust on a shelf - & found the heater blower circuit.
According to that, it is an actual resistor bank & not a preset voltage regulator, but anyway, in order just to get something working, you could put a 12 volt feed directly onto the solid red wire (marked Rt in diagram below) that feeds the blower motor, & you should get full fan power output.
At least this would test that the blower motor actually works, & if it does, then you can go about sorting the wiring properly.
Keep us updated on your progress
