Car Forum / BMW Cars / May 2008'88 325 - Is my air compressor working?
Having A/C troubles here. I turn the temp dial to the left, push the air vent slides to the middle and push the a/c button. The engine rpm comes up about 200 and the engine sounds like it's working way harder. Air that's not hot comes out of the console but there's no air conditioning going on here to speak of. I ran it about 10 minutes without any change. Does this mean that the compressor is ok but the R12 has leaked out, melting the polar ice caps? I can't see anything in the sight glass located near the passenger side headlight bucket but if I push the fill thingy that's next to it with my keys you can hear air leaking out. Any advice for do it yourselfers? >Having A/C troubles here. I turn the temp dial to the left, push the >air vent slides to the middle and push the a/c button. The engine rpm >comes up about 200 The engine speed should stay the same as the extra fueling and revs are there to compensate for the compressor drag. If you have no liquid to compress then the compressor will not run as the pressure switch will not allow the clutch to engage and if there is JUST enough pressure there to let it run there won't be any cooling and the compressor ha very little to compress. >and the engine sounds like it's working way harder. >Air that's not hot comes out of the console but there's no air >conditioning going on here to speak of.

You will also need a filter/drier and possible an new condenser and O rings >melting the polar ice caps? Do you really think that is actually happening???? It's all a great big con to hike the price of fuel and to reduce the use of leisure time and to ban cars from city centers in the name of conservation.... load of old bollocks! >I can't see anything in the sight glass Therefore you are EMPTY >located near the passenger side headlight bucket but if I push the >fill thingy that's next to it with my keys you can hear air leaking >out. Any advice for do it yourselfers? If you live in Alaska do nothing - if you live in CA or FL then get it fixed.

My guess is that you have very little refrigerant left, so you will need to find the leak and refill. > If you live in Alaska do nothing - if you live in CA or FL then get it > fixed.

All five of mine have done this. 5 or 6 starting with a '76 E3 - you probably never heard of that one. 3.3Csi 323 x 2 730 & 735 then E38 740i x 2 and now an E65 730d SE + the odd Lambo and a couple of Ferraris not to mention a whole host of Mercedes, UK Fords and a few Nissan Skylines.
