Did this video help you?

Andrew Parrish: Great video! Because of it, I was able o fix my 330ci. Had a hell of a time with the HvAC cover though. Overall, took about an hour. ;-)

BJM1931: i replaced the FSU easily. But can't replace the hvac tunnel. You seemed to cut away here. Any ideas?

KB GAN: Good job.  I was able to replaced my FSR by following your presentation. I did it in an hour. Thanks!

Norbert brilliant: ps: you dont need to buy a new and change the FSR,  you can repair it.  write me and i send u how to repair it, its easy 

Smoove-Z: anyone had any issues with a after market/ non genuine FSR?

Norm Armstrong: No need for words when the detail is as great as your video! Saved me tons of time, thanks!!

Raymond Chiu: good intruction, thanks

Shameka Latres: best video i seen on here to replace the FSR.

Mineves Vronsky: Thank you, thank you, thank you. There are several videos on YouTube, but yours is the most efficient one. I followed your steps and it took me about 30 minutes to replace faulty FSR on my E46. FSR was failing last two years (blower was changing speed on its own) but last week finally died........

Yury Santos: my blower motor  just do not stop.. still working ...

Nick McKenzie: What side is the FSR on in a right hand drive car ?

Randy Graham: Great job on this video. I would never have guessed the ventilation box would pull out of the way like you showed.  Did the job in about an hour. Nice!

ghooyt: Hi "BMW 3 Series" Thank you so much for this video! I was able to follow your instructions to get my FSR changed out last night, and everything seem to be working ok right now. I only problem I had was that I didn't have the Torx20 screw driver like you did, but those "L" shaped Allen key equivalent. Needed some patience to get them out. Need to invest in Torx screw set :)

Mr DJ: I was having one of the common problems with the heat so I replaced the Final Stage Resistor, the blower works perfectly for a couple of days but then all the sudden the blower stop working. I have checked fuses and all look normal. Before I try to replace the heat blower I would like if it is any other thing that I should take a look? Thx

BMW 3 Series: most likely the fsr, but you can try measure the battery voltage first

Wolfgang Ezeh: My e46 blows on start up of the car for a few seconds and erratically in between. The car had been left standing for over one year. Is it the FSU/FSR or do I need a new battery?

BMW 3 Series: May well be the FSR. It has an electronic circuit inside and is powered all the time. So a fail in the FSR can cause a battery drain....and have en fan running a life on it's own

Albert Marquez: this will not shut off. i finally disconnected the FSD connector for the mean while just so this wouldn't drain my battery. any ideas what this might be?

Albert Marquez: hello, i have an issue with this repair if you can please advise. i did this, just as you show here, though i dont have a thermal cam (lol). once replaced, and the FSR installed, i tested the fan speed controls and Auto AC functions again. This time, it worked like a charm. low speed, high speed and auto all performed well. however, going to turn the car off and pack everything up, the fan did not shut off. this remained on after i turned the AC off, turned the car off etc.

Dimitrios K: You totally saved me, I was on line for a month now trying to find someone who knows what he is talking about, half an hour later my a/c is working again, thank you very much for the video,
