Hey guys, I own a '99 m3 and have never had a functioning AC so I don't know what the problem is or where to start. Everything else works fine. Was wondering what could the possibilities be other than need of a recharge or some type of leak somewhere. And where to locate and repair that leak. I understand there are other possible issues like a bad compressor but I'm pretty sure I'm getting ahead of myself. Would appreciate any comments/suggestions. Thanks.
