Car Forum / BMW Cars / April 2005Air Con has stopped working
Hi I turned the aircon on my 2000 e46 323Ci today and although the dash indicator lights, the air coming from the vents doesn't feel cold. It worked last summer. I can see a small dip in revs at idle the instant the button is pressed, these revs then normalise so that would suggest the compressor is working. I am assuming therefore that the aircon needs regassing. Is this a fair assumption? How often do I need to do this? Is there a way of telling if this is really the problem? Any help appreciated. Cheers Rich > Hi > [quoted text clipped - 10 lines] > Cheers > Rich Have you used the air-con system regularly? I'd take it to an air-con specialist (not a BMW Stealer!) and get a leak test (think this is what its called) performed - this will show if it just a re-gas that's needed, or more expensive remedial work. Most air-con systems need to be switched on even during winter to keep all the compressor seals lubricated. Jason Russell >> Hi >> [quoted text clipped - 21 lines] > > Jason Russell Jason is right Seems as if you did not use the aircon at all, for quite some time. The manual suggests using it at least once a month, to prevent the seals from drying out and leaking your gas out. During a regas they will put some "oil" in the system as well. This should lube the seals and your problem should be fixed. MW My wife's LS400 is almost 14 years old. The AC is used none at all each winter. The AC has never been serviced and still cools great. Had similar experiences with a Mazda 626, a Ford F150, over 10 years each and a Yukon XL for 5 years. If not using the AC during the winter months causes the refrigerant to be lost on a car this old, there is something very wrong with the AC system or its design. - GRL >>> Hi >>> [quoted text clipped - 31 lines] > > MW > My wife's LS400 is almost 14 years old.

YMMV, but I'd say prevention is better than a cure for air-con ills. > My wife's LS400 is almost 14 years old. The AC is used none at all > each winter.

I've got an older car that runs the compressor when you select 'defrost'. I'd say this is to make sure it gets used in the winter at some time - although it would depend on how hard your winters are.  Signature*If a thing is worth doing, wouldn't it have been done already? Dave Plowman dave@davenoise.co.uk London SW To e-mail, change noise into sound. So in summary, what you guys are saying is that I screwed my aircon because I didn't read the manual and run the compressor periodically. I screw up the assembly of flat pack furniture for the same reason. Thanks for your help.

Drawers which tip the contents onto the floor when pulled out are fun. Signature*Middle age is when work is a lot less fun - and fun a lot more work.

LOL - too true Dave, too true Except when it happens to your better half! Then the ensuing bollocking isn't so funny..lol >> So in summary, what you guys are saying is that I screwed my aircon >> because I didn't read the manual and run the compressor periodically.

SignatureDan. the revs will dip due to the current being drawn on the air con unit it does it on my 316 cheers darren |
