A/C Not cooling
My A/C has stopped working when I turn it on the A/C button flashes a few times and then stays on and all I get is hot air fan works great engine temp normal I purchased a new block looking fuse at the BMW dealer to see if that would help. nothing the only thing left is to check the pressure.Has anybody had this problem

Argh. My light doesn't flash, but it blows just marginally cold air. Guess I should confirm that it's spinning. Trying to decide if it's better to just replace the compressor, or pay someone an arm and a leg to tell me I need to replace the compressor. Not happy about this in a 5 year old car. (R134a is full)

Don't jump to expensive conclusions. If you're not confidant about diagnosing your problem, take it to somebody you trust and get the real story.....just because someone here lost a compressor doesn't mean you did too. A/ C systems have a lot of components, there can be a lot of reasons why yours isn't working correctly.
I have an '03 MCS and I've never been impressed with the amount of air coming from the dash vents, but I just thought that's the way it was, since it does cool the car eventually, and the air that does come out of the vents is pretty cold, especially on recirc.
This past weekend I rode in a guys '02 MCS and what a revelation - it blows like crazy! Bottom line, I probably have a vacuum leak somewhere that's not allowing a vent to open or close properly, restricitng the amount of air flow I get out of the vents.
Moral of the story, don't make assumptions!

Always a good idea.
A/C diagnostics and repair is not rocket science. But it does take the right tools and some experience that are both well worth paying for.
That is also true. That said it seems that there are a bunch of A/C clutches from '02s-04s are failing. But it is easy to see that the clutch doesn't engage and there are no fuse or relay problems.
It turns out that a lot of the early Minis came with a light charge. Sometimes just a touch more self-installed works. But to be sure I evacuated and recharged early when I got my '03 and it made a big difference. Again, it was just under the capacity spec and a recharge made a BIG difference. And there were no leaks or other problems. But your could be something more serious like a small hole in the condenser or loose hose. Again someone with experience will know.
Is your heat blowing good? If so the vents are probably working correctly.
Yup.

Failure of the radiator's low speed fan relay can also cause the A/C not to cool properly and can eventually cause premature failure of the A/C compressor due to high temperatures.
R50/53's MINIs suffer from crappy radiator fan relays that need replacement every 3 years. This time around I purchased an aftermarket fan relay from Chad at Detroit Tuned (Forum sponsors) and had my independent install it. works like a charm and saved my self well over $350 replacing the whole fan assembly.

Change that, I bet it helps. Mine was nasty...

I don't know if air temps dropped, but the volume of air increased dramatically after replacing it.

My airflow sucks. I had the A/C system checked earlier this week and everything was fine. But I forgot to look over the cabin filter. I live in Miami where is hot and humid year round. The MINI's A/C system is not the best out there, but I don't remember having to keep the fan in speeds 3 and 4 all the time just to cool down the interior.
Per my records, I don't think the filter has been replaced in over 3 years. I suspect I am about to be pleasantly surprised once it gets replaced (Heading out to my independent as I type this).

So lo and behold my cabin air filter was beyond filthy when I pulled it out. Getting it replaced later today. The shop did not have any that fits the R53 filter compartment under the glove box. I think it is by miracle that I am getting any airflow coming out from the dash vents.
Moral of the story. Replace the filter at least once a year.
