Low Speed Fan Resistor - we need solution

I stand corrected... I will edit my post

Slightly off topic talking about stainless, I am surprised how poor the quality of the fasteners and fittings are on the Mini, many of the nuts bolts and brackets have corroded, on inspection they seem to have either no plating or just lick of paint.
all the fittings on my 1980 Ford which I have had from new and has not been garaged are fine. I'm thinking to get a zinc plating kit off ebay,

For the record I do a lot of work on Apple laptops and in the old days there was never a stripped screw. Now, at least half of them strip when you take them out even with the right size driver which I have. I guess Mini and Apple are saving a bit of cash using substandard fasteners. Unfortunately I think it costs us more in the end.
Rich-Who wishes that the MCS exhaust was stainless as well.

I've just had an Idea, if you have just fitted a new fan and resistor assembly with pigtails, could you not wire up the aftermarket resistor as well, as it is in parallel the resistance would be the same and as the load is 77w each resistor would only be taking half that, then if one fails ( which will be unlikely as they are running cooler) the other automatically take over the full load...

Per the Bentley manual, and confirmed by my ScanGauge, the fan operates at low speed at 221F, and turns off at 214F. The fan switches to high speed at 234F and remains on high until the coolant temps drops by 7F. Supposedly it also turns on when the AC is on and the AC system pressure reaches 8 bar (114psi)
I confirmed today that I have joined the dubious 'fan resistor failure club' (FRFC). The AC didn't cause the fan to turn on, and it didn't kick on high until 234F. Funny enough, living on the coast I had a hard time getting it up to 234F!
Does anyone know if the fan failure would cause the AC to fail? I only noticed the problem because my AC stopped blowing cold. The clutch appears to work, and the system is full (refilled it a while ago, which resulted in cold air once again) but with the AC on the vents give a weezing noise, and no cold air. Any thoughts on whether it's worth replacing the fan and buttoning up to see if the system will kick in if the fan blows? Or am I in for a new compressor?

On Artoo when I replaced the fan two weeks ago, the A/C now works better. I had the compressor replaced last year because the clutch was bad. That would have NOTHING to do with the fan. And if your clutch is engaging then, although service mode is a pain, I would replace the fan and see what happens before I went at anything on the A/C system as those parts are priced outrageous.

I am going to go ahead and order a low speed fan, does anyone have a part number or a link to the one I should buy? Will it come with everything needed? My car is running a bit hot and the dealer said this woul need to be replaced. The temp gauge will go past the halfway mark but never into the red, maybe 3/4 of the way up the guage.

Please Help
I thought for sure my resistor needed to be replaced (no low speed fan when the AC is on, AC blows ambient air only)...I even ordered a new fan...however, today i decided to run 12v through my existing fan to verify for sure before I attampt "service mode", and low and be-hold, the fan spun, both high and low wires worked!!!
So now i'm thouroughly confused. I checked all the fuses and relays and they are ok. But I am not getting any power to the fan???
I am at a loss, please help.

How (where) did you run the 12V through the fan?

Continuity for the fuses was good, but I will check continuity from the fuse to the fan wire(good idea). I ran 12v directly to the fan by removing the connector and running power through the fans connector with a 12v battery i have.
I was thinking temp sensor too, but doesn't the low speed fan automatically come on when the AC is on? Maybe not?
Keep the ideas coming, I'm stumped!

Update:
I am still happy with my resistor installation documented earlier, mounted to wiring bracket near a/c freon connections. I don't drive a lot, but we have had some good hot days. The air flow hits the resistor here, so it does not appear to stew and climb in temperature indefinitely.
That mount to the cast aluminum engine bracket scares me, mostly because of the effort to drill four straight holes and then tap them freehand. Aluminum loves to seize on taps, and if you bust a tap there, now you have to drill four new holes and start over.
If you are tapping in aluminum, the typical recommended tap fluid is kerosene. However, over many years I have found olive oil is a great tap fluid as well. You will be amazed to see the metal particles disperse off of a tap when you stir it in a cup of olive oil. Non-toxic too!
Tip: check your tap drill size and go a number drill larger. Most tap drill charts are sized for 75% depth of thread, and that is excessive for most general applications, especially this one.

You all love your Minis too much you wouldn't worry about drilling into your old Fords
seriously the place where it needs to be drilled it is only a few mm thick you wont break a tap there is like going through butter. Don't mount it too high though, the back of the headlight nearly hits the top part of the mount when the bonnet is closed, you will pinch the wires in the armoured cable.

I have been reading this thread for awhile. and not sure if I have the same problem. it's been very hot here. and anytime I shut my mini off the high speed fan is loud for a split second after I shut the key off.
anway. so lets pretend I do have this problem. what does it really hurt? is there any damage or reason why I need to worry about it.. after all the higher speed fan is keeping it cool right? so lets say I dont fix the problem (if I have it) other than the noise. should I fix it?

You may not.
The bottom line for you is that you may not have a problem at all. To tell turn on your A/C and see if the fan is spinning. If it is and not on high, then you are good to go. At least for now.

ive been following and reading this thread for a while now... I do not want to replace the fan assembly, but i cannot find the replacement resistor (non-oem) anywhere... if anyone has a link to the resistor i need, will you please repost. I have looked at the mouser link but they have them on back order... im really trying to get one ordered and sent to me asap..

I bought mine here

He is also out of stock they must of all sold to mini and Rover owners

Is this what I am looking for to address the low speed fan? Went to the dealer today and while I like the service I am not willing to shell out as much as they want to replace it.

Not sure if this is my problem or not
I have a 04 R50. The other day the air conditioner was working fine on the way home. 20 minutes later I drive to the store and no air conditioner. It is only blowing ambient air. I read that the low power fan could cause this so I decided to check. Sure enough, the low fan is not working. Running the car in the garage for 10 minutes or so the fan kicks on high then shuts off. The whole time I have the air conditioner on and it is still blowing ambient air. Could it be that I swap out the resistor and the air conditioner start to work again? If so, did anyone put together the resistor kit? From what I have read, it seems to me that there is a five minute fix? Something about wiring the resistor near the plug without removing anything.
I am so confused...

i have read in some other places that once you get the low speed fan going again, then possibly just installing new freon into the a/c system could get the compressor going again.
ive read that with the low speed fan out, that the pressure in the a/c system causes it to dry up or evac its self... and apparently the compressor will not click on until refilled.
Of course this is unverified... does anyone here know if this is true or not?
