SOURCE: leaking coolant from engine..
Unfortunately, This Problem is Going to Be Either a Blown Head Gasket or a Cracked Block. Just in Case, Check all the Hoses and Check and see if your Model Has a Transmission Cooler Installed, Hopefully on of these is the Culprit. Please Rate My Response! Thanks!

SOURCE: heater blower not working
I don't know if this is a long-term solution but I found it on another "how-to" website: on my 2001 E46 I removed the fuse (#50) for one minute. Something about the transistors inside the FSU (final stage unit, or blower resistor) resetting themselves with the constant power removed. I replaced it and drove home, which is a 1-hr drive, and the fan was on steady the whole time. Which it hasn't done in the 3 yrs I've owned it. I tested it at other speeds and it worked well. Don't know how long it will last though. If not, you need to replace the Blower Resistor - there about $75.
