2001 BMW 330i..Fan for AC/vent not working?

My daughter has a 330i, her AC or vent fan quit working, the display shows it working when pushing the button but no air flow. Could this be as simple as a fuse change?

    I am checking for fuse numbers 75 and 76 .  I cannot find them in the glove box compartment where all other fuses are.  Does anyone know where they are?

    Yes, had the same problem once. I turned down the fan speed until the unit turned off and then turned it back up. I haven't had problems since (knocking on wood...).

    2001 bmw 520i SE fans/AC not working all of a hot or cold air.........although display showing increase and decrease of fan speed.

    I have an 02 525i and the AC fan (or fans) has a mind of it's own. Races from full on, down to the proper setting and back again, all over the place. Car has full climate control with electronic control of the fan. It seems to improve once it's driven a bit but I'm not certain of that. Fan speed indicator does not seem to control anything. I've tried to get to any of the controls but without a manual that dash is buttoned up tight!

    I also have a 2001 330ci and have experienced the fan pulsing, going high and then low, and it has recently quit working. The display indicates that the fan is running and you can change the fan speed but it does not come on.

    Thank you for your help.

I just replaced the "Final Stage Resistor" in my 2001 330i. Fixed the probelm 100% !!!. I followed the instructions descibed found here and on other sites. A little challenging, mostly becasue I hate working upside down, but the repair went as descibed. If you're even moderatley handy this is a straighforward project. I'd say about 60 minutes to carefully remove everything and about 30 minutes to put it all back together. Beats $500+ at the dealer!

The problem is the ac resistor located on the passenger side of the center console. It's a little difficult to get to but not impossible. If i remember correctly it cost about 100.00$ from your BMW dealer. If you do a internet search for problems with BMW a/c you will find many post and fixes. BMW has made 3 revisions to this resistor over the past few years. If replacing this parts does not fix it then the only other cause will be the climate control module located in your climate control display. This is a very expensive part.Remove the plastic cover behind the glove box (passenger side) look toward the drivers side close to the bulkhead and it will be there, disconnect the plug, release the clip and pull back gentally (don't break the clips!) it's pretty easy.
Good Luck

Guys, I got the blower fixed of my BMW 520i. It was the resistor. The part cost me £50 and labour was charged at £45 (for half an hours work). The guy at the garage told me that it was a common problem with the BMW cars. Please do not go to a dealer. They said that it will cost me between £80-£160 for just diagnosis of the problem. So I would advise, please go to a garage (specialising in BMW reparis) and talk to them about the resistor. In that way they cannot mess around with you by giving stories as to how complicated the problem is and that how long it will take.

I have a 2001 BMW 330I. My problem is with the heat blower. It works on and off. It goes on for a while then turns off by itself. Then out of nowhere, it goes on again! And so on... What is the solution,...

If the blower is the one cutting off iether at AC/heater mode, it could be a faulty fan resistor. To replace it, you have to take off RH side front kick panel, foot air vent and use torx bit.

2001 BMW 330ci Blower Fan quit working

sounds like the resister for the fan is failing. it is located under the dash on the duct work for the blower (fan). you will see two wires going to it. unscrew the bolts or screws that hold it in and replace it with a new one. it should work fine after that.

2001 BMW 330i..Fan for AC/vent not working?

it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.
