Air Conditioning problems! Mini Cooper 2002

[N Mini 61]

I have had cronic problems with the air conditioning on my 2002 Mini Cooper Launch Edition.

I have had my car in the shop oh I'm guessing probably at least 8 times to have the a/c repaired.

The last time was fall last year when I met with a Regional BMW Rep and the Service Manager, and they agreed to replace the AC.

Well, last week, same problem... kind of a grinding noise that only happens when the a/c is turned on. But in this case last week, the a/c light started flashing and the a/c shut down and then I got a high temp on the engine...

Although the dealer has been great about this, it has been 4 years in the making. I have yet again booked an appointment a week and half from now.. so any insite that someone else may provide that I can take back to the dealer would be great!!!

Have you had any of the fans replaced? Your problems sound exactly like what I experienced, and although I've not gone through a whole summer with a replacement fan, it did cure the problem so far.

Thanks, I don't think we even considered that the fans may be the issue! I will certainly pass this along when I bring it in for service.

Sorry for the late response but I had the exact same problem with 2002 MCS, power steering fan was stuck (due to winter) and caused the fuse to blow up. Result was that the engine was overheating and A/C was not functioning properly. They corrected this on the 2003 models by having a separate circuit for each of the engine fans.

My 2002 MINI Cooper 5-speed with manual AC/Heat controls has had no problems so far.

The aircon cannot cause the engine to overheat. There is not enough heat coming out of the aircon condenser (the aircon radiator in front of the engine radiator) to heat the air by enough to overheat the engine.

It sounds like the fan isn't working. That will stop the aircon working and make the engine overheat. It could be a blockage stopping air getting through both radiators.

Hi,

My 2002 Cooper S Air Con has stopped working. The air con light is on but not cooling the car. I have also noticed the engine fan I presume whilst parking coming on after the engine is switched off. This has happened at the same time the air con stopped working. Could somebody try help please.
Could I have a blown fuse, if so where?
Thanks in advance.

The clutch on the engine driven A/C compressor won't cut in if the gas level has dropped to protect itself from damage. Have the system checked for leaks and regassed if required as a first step.

Kwik Fit will check and not charge if they can't get it 10% colder!

Recharge or No Charge

Let Kwik Fit recharge your Air Con while-u-wait. We will replace and recharge lubricant and refrigerant levels in line with your manufacturer’s recommendation. If we cannot improve the coolest vent temperature from your car by more than 10% when measured in degrees Celsius - then you pay nothing at all.*

Hi
Yes I had it charged by Kwik Fit and no charge as it was not coming on.
I replaced the fuse for compressor. Number 7 30amp under bonnet, although this seemed ok. Kwik fit said it was low on gas and when they recharged it had nearly double the amount. No leaks were showing just the compressor fails to kick in when button is pressed. The fans blow and the A/C light comes on but I notice hardly no difference in air temperature. The fault seems intermittent as I am sure a few times it did work and I notice that smell of the air con. Are there any loose connections to check? I am hoping
this is something simple. It is also a bit hard to check what with being fairly cold anyway it's hard to tell if it's working correctly.
Thanks for your input.
Regards

I think you will need an air con specialist to do some basic tests as there are several things it could be and it is too costly to replace random parts. It may be something minor like just a relay has failed......but if it is the compressor (expensive) all is not lost as good used Mini ones are available from specialist Mini breakers.
Perhaps try a good local mobile air con repair specialist to diagnose.

Haynes do an Air Con repair manual but there is little than can be done diy.

Ok thanks. Think I will get it diagnosed by a mobile Air Con specialist. I am based in Waltham Abbey, Essex and work in Hackney, London. If anybody could recommend a specialist who is reasonable who can diagnose would be grateful.
Many thanks

Thanks. I will check the relay at the weekend. It seems to work intermittently so it could be relay.

Thanks again.

Changed the relay and fuse. Working! :-) However don't hear a noise of the compressor kicking in. Maybe I have a quiet one. Definitely blowing cold though.
I changed the Green relay number 2 in engine bay and fuse 7 underneath.
