I had the same problem, replacing the filter not only doubled the flow on full, but also the lower settings began working.
I can't see a good reason why this fixed it, but it did.

They didn't become available until around 1991.

I had a clogged filter on my 94 when I bought it. The fan still blew air but it was like the amount of air was off...on position 1 you could barely feel it, position 2 felt like what position 1 SHOULD have felt like. I'm with Jeff (and Dick) on this one, check out the sword.

Jake Dog, I'll have to vote for the SWORD too. While there are websites that describe changing the mosfet transistors on the sword, which apparently is what usually fails causing the sword to either stop working or only work on one speed, I opted to just buy a rebuilt sword due to the fact I just didnt have the time nor confidence to try the repair myself and was told, and also read, that there was only about a 50/50 chance if success.

There is a guy who sells them on ebay for a reasonable price and 2 year warranty. Check out item # 7905327462 on ebay and you'll see. When I bought mine I was like you and wasnt 100% sure it was my sword but he said if I bought one and it turned out to not be what I needed then I could return it for a refund and I'd only be out the shipping of about $6, I thought that was fair. He also walked me thru the install which wasnt bad at all and He'll also buy your defective sword from you too.

There are a couple of guys on this forum that bought from him and were satisfied. Anyway I just thought I'd make you aware of a good source in case you choose not to try and fix it yourself. Good luck

If your compressor is working fine then most likely it is your relay called a limit switch: http://www.realoem.com/bmw/showparts...68&hg=64&fg=45

I replaced this and the A/C worked fine.

There is something wrong with my screen. It says somebody posted a reply to a 6 year old thread. Should I inform Microsoft or get my mate Steve round? He says he works in IT but that seems to be a contradiction in terms
