I have a 95 325is, and I live in Phoenix. Man does my AC suck, as a matter of fact all the e36ís Iíve rode in have crappy ACís. This last weekend I recharged my freon and it didnít help at all. On full blast the fan still seems a little weak, so I plan on changing my cabin microfilter. Still, I expect my AC will suck. The AC does indeed work, but it just doesnít compare to other makes ACís. At this point I want to know if anybody has upgraded their AC, as opposed to merely trying to fix it. Iím sure in some states these stock e36 ACís cut it but NOT IN PHOENIX, HELP!
You should also check your auxilary fan, make sure it runs on low speed when the ac compressor is running, this fan cool down the ac radiator that is in front of the engine radiator. This fan serves to cool down the ac radiator when its running, will run on low speed, and if something goes worng with your cooling it will kick in in high speed to cool down your car, if the mechanical fan fails.
Not only replace your cabin filter, check your electrical fan, resistor, fuses and relays, make sure contacts are clean, special the one under the bumper that is the plug for the fan, that plug tends to suffer a lot of water damage, since it sits too low.
And also, on the ac dryer, is a little round silver looking can with hoses going to it, this is where the freon is dryed and stored on the system, it sits under the windshild washer fluid, there is a pressure swicht that sits on top of the can, is this swicht fails, the ac system will work poorly, since the system thinks the ac is working under high or low pressure, to fix this pull the plugs out and clean the contacts, these plugs get dirty easily and will provoke malfunctions. But keep in mind that if the siwcht itself is broken, it will need replacement, meaning that oyu will have to evacuate the freon on a professional machine and then replace the switch, not that complicated, just needs the shop to remove and then fill your freon, hope this helps;.
