Anyone remove the A/C from your street car?
If you did, how did you keep the radiator fan from running all the time?
My car now has no A/C and we tried several different things to return the fan to normal operation, but none of these worked...
1) ground the A/C connector from the harness
2) 12 volts to the same connector
3) jumped the pressure switch connector from the harness
with no ground to the compressor connector
4) jumped the pressure switch connector from the harness
with a ground to the compressor
5) pulled both A/C relays from the box underhood
6) pulled A/C fuse from same box
Obviously, the DME is seeing the A/C as being "on" with nothing plugged into the compressor harness and with no pressure at the switch.
I've never seen a MINI from the factory without A/C, but they offer this to replace the compressor...

...which I have installed, so I wonder if there is a DME flash for vehicles without A/C?
Anybody? Any input? Thanks.

I have that part on my car
I purchased a salvage mini and putting it back together I decided on the pulley rather that trying to replace the system. There was a sensor or relay that was located in the air box corner that I had to replace to get my fan to stop running. My car is getting tuned today so I do not have it to look at what I replaced. I can let you know this weekend if you do not get it solved.

I think you may be referring to the pressure switch that is underneath in the general area where the air box sits.
That's all you did, was plug the switch back in? The fan cycles normally now?
I haven't tried that yet, the switch is still on the line which is up at the shop.
Thanks again for your input.

Wow, and the fan functions as it's supposed to?
