What side is the FSR on in a right hand drive car ?
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!
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
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 :)
Just a warning: You pretty much have to be Gumby to get this part out/in 😀
It’s not in a very convenient place.
How do you know if you have to replace this part.?
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,
Thanks for the nice descriptive video, very detailed, I can now finish this
off!! Way to go!!!
LOL- I’m nursing those same scratches. There’s a lot of metal tabs in there
that’s like sticking your hand into barbed wire 🙂
Can you kind people please give me some advice?. I have 3 series touring
e46 model, my blower works intermitedly and rear heater is also not
working. My local mechanic said it was the climate control panel as it is a
common fault but also could be FSR. As it seems that both blower and rear
heater have been affected would you guys say that it is more likely the
climate control panel itself rather than FSR?. Thanks. P.S Best FSR repair
video on youtube. Clear, HD quality, no shaking camera etc
My pleasure. I would have added some oral instructions if my english was
better, but glad the texts can do it
Good video i have a 330ci 2001 and last day the controls works fine but do
not blowing, i have to drive the car with out heat, but today after my
second intent it works good and still working. Should i replace it?
awesome video, really helped with the job. hvac tunnel worried me! but with
a little extra effort it pulled right out. the far was tight in place and
took a lot of patience to wiggle out. heater now working. thanks for
posting, e46 is definitely a do it yourself kind of car.
Ok so my ac and heat turns on in my car but its just not blowing out
anything, would this be the solution to fix it?
Thank you! This is the best video on this job that I could find!
Thanks so much for this video! Super helpful. The only thing different on
my 2000 328i was that the FSU was held in by two more T20 screws. The
hardest part of the whole thing was getting the HVAC tunnel back in! My
climate control fan is working again, just in time for hot weather!
Its the FSR 🙂 I bought a used FSR/FSU from the local BMW stealer for ½
price. I use a tripod for my HD cam to make a good quality video. Have to
agree with you, I hate those video whit shaking camera. If my english was
better, I would also give out instructions during the repair, but hope the
texts are ok 🙂
I think you should try check the fsr
Good video
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
Thanks, good video, took me 45 minutes after watching your video. I did
have to use knee pads though, and disconnect the cables for the glove box,
to get it out of my way. Part cost me 60 bucks, and now have heat, thanks
again for your effort in creating this DIY video, 🙂
Hi, do you live in Flensburg? If yes, I wanted to ask you to help me
replace my fsr at my bmw e46. Greetings from Flensburg.
Many thanks for the video- I did mine in about 35 minutes thanks to you!
The vent wasnt too bad but certainly the most difficult part with the next
being the annoying tab that held in place the old FSR:) thanks again!
And I admit it took me a bit longer as well. I cut out the a bit in the
video where I didnt do the right tasks 🙂
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?
If the blower motor is running up and down in speed for no reason or if the
blower motor isnt running at all, it’s most likely the FSR/FSU that is
failing
This video right on the money, saved me alot of money and it took me less
than and hour Thank you sir!!!
This video saved me at least 100 euros. Thank you!
Just use a bit of force. Its not glued or fastened in any way. So moving it
up and down while pulling it and it will come out
awesome video step by step, i did mine in an hour and it works perfectly,
getting that vent back in was a pain in the ass
Good video but I can’t figure out how to remove HVAC tunnel
hi I have a question my bmw blowers not working the it does not blow the
air at all previously it do that some thing it starting blowing some times
not but now a couple of days its totally shut down not blowing the cold air
as well as warn air I checked all the fuses they are fine infect when I
remove one of the fuse for blower and put if back it makes me feel that
their is nothing wrong with the wiring but I don’t want to spend 100s of $
to mechanic’s
Hi. I have got exact same problem like you.. Could you find the reason? If
yes. Please post it here..
One question. My fan isn’t working at all, when I switch the heat ON i hear
some noise like it’s tryin’ to turn it on but nothing happens. I replaced
the FSU about year and a half ago, and I know how it behaves when it’s a
faulty FSU. Any suggestions please?
If the blower motor is running up and down in speed for no reason or if the
blower motor isnt running at all, it’s most likely the FSR/FSU that is

Yup, I scratched my hand as you can see in the video 🙁
Thank you for posting this. I was able to do this repair for less than
$50.00 and it worked! Everything went back and looks professional. I admit
it did take me about 2 hours total but it was well worth it. only one small
scrape on my knuckle. Thanks again for taking the time to post this.
A failing FSU/FSR can cause the fan to not spin at all, spin with its own
life (up and down) or just not possible to adjust the speed on. Just
because it was changed once, does not mean that it can’t fail again. This
part is poorly designed and is likely to fail
This is a fantastic video for this procedure…I’m going to install it
right now.
Thank you vor the video, excellent job and helps a lot on how to change
this part.
My e46 blows on start up of the car for a few seconds and erratically in
between. The car had been left standing for over one year. Is it the
FSU/FSR or do I need a new battery?
Thanks! now back to my A/C, I was sweating my ass off.
hello, i have an issue with this repair if you can please advise. i did
this, just as you show here, though i dont have a thermal cam (lol). once
replaced, and the FSR installed, i tested the fan speed controls and Auto
AC functions again. This time, it worked like a charm. low speed, high
speed and auto all performed well. however, going to turn the car off and
pack everything up, the fan did not shut off. this remained on after i
turned the AC off, turned the car off etc.
i did the samthing no heat im pissd
hi i have a bmw e6 318 i and the heater fan works good BUT i do NOT get any
HEAT comeing out NO HEAT what do i do to fix it theres no HEAT ??????? help
me
hey thanx i did mine for under 30minute imagine at he garage how much they
charge me -_-””’ 200$
Thanks a million. Saved me a lot of time watching this before hand.
most likely the fsr, but you can try measure the battery voltage first
