My 2000 e46 bmw heater blower not working, i've checked the fuse it's not that.when i press it on i can here movement within the dash board just no air blowing through. what could it be can someone please help where and how to get into the blower location for BMW 323i Station Wagon.
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.
www.bimmerwerkz.com is an excellent source of info! They have pics, utube video, and diagrams to help you.
The blower is not the problem
The problem is a faulty final stage resitor located
on the passenger side under the dash.
Very common - easy to replace.
