Thank you for posting this. I was able to follow the directions easily and with a $20 part and 30 minutes, I had it switched out. Everything works now. Thank you!
worked perfect, I didn't have to remove the glove compartment, worked fine just removing the plate underneath the GC and the side panel. Thanks for the video
i know this is an old video but finally had this issue come up on my 02 x5 and this solved it and saved me a trip to the shop. very helpful, thanks for the walkthrough
This video was very helpful . I would like to add that the original part does not look the same as the most recent part from the dealer . The design was updated but still fits . This was my first attempt at fixing the blower problem and it happened to be this part if it wasn't for the video i would of had to troubleshoot from the manual .
Thank you very much, excellent video. I just installed my FSU and everything is working just fine. Save over $300 in Canada. God bless you and please keep posting.
thank you for the well put together video! it makes a 100% difference when you are already familiar with what you are looking at. i replaced my FSU and the heater is working so now i can add all the coolant i lost from another repair session of replacing my 2 pulleys (because of financial hardship i did them one at a time i had to remove the top radiaor hose twice). i couldnt completely fill or bleed the cooling system without my heater on. i am sure many already know this but i felt i should explain. this is especially good because i live in the desert ITS SUMMER NOW AND I HAVE A/C, TOO?! what a novel concept! thanks again, Otto!
Word of caution for RHD X5 owners. The FSR is on the drivers side, NOT the glovebox side. Remove the cover under the steering wheel and the trim panel at the side of the centre console. You can then see the FSR same as in this video
Thanks to this video I was able to DIY swap out this part on my 1998 e39. There are a couple of differences, the carpeted portion which requires removing has sliding clips instead of platic pop rivets. They slide towards the rear of the car once the single screw is undone. Also, the transistor itself is situated deeper in the console, and is a massive pain to get leverage on the retaining lever. Oh and the old part has bigger metal prongs of a different metal formula. But yeah, thanks a heap for this video, made the job much easier than it might have been.
Hi Bavarian Autosport, first i would like to thank you for taking the time to make this video. i had the same problem with my 03 525 M sport the blower would come on and off and that's when the engine is of and the key removed my battery kept loosing it's power and need to be recharged so i replaced the Resistor and now it's sweet, but in the UK model it's on the driver side RHD and all i did was to removed the panel under the steering wheel and that's all the panel i removed to removed the Resistor. thanks again.
After watching your video, I was able to replace the FSU on my 2003 BMW X5. I was able to reach over and replace it without removing the glove box. Thanks
Hey Robert, how were you able to do it without removing the glovebox? Can you explain a little bit of what procedure you used/steps you took to get at it? - Thanks!
Good video, didnt know there was a clip which was hanging me up, this video clearly shows that. Easy fix to non blowing AC! The chinese knock off on ebay works perfectly, good thing i only spent $18 versus the $127 at Autozone
The Blower resistor on a 2004 E60 is located under center of dash below and cannot be found from the side like this video describes. You have to remove blower motor to get at resistor. Leave the dashboard on if you can.
this worked for me. symptoms were; air cutting out, a few instances of air on full blast, and finally air stopped completely. i have an X5 E53 and i did need to remove the glovebox as described. the old resistor would not come free of its electrical connector. had to get a screwdriver in there and pry it free while depressing the tabs on the connector. very difficult to do without removing the glovebox (which is easy)
Is this the same procedure for an f01? cant find anything online. I can see where it goes on the blower motor, i am just not sure if its accessed from that area or from the top of dash. any help is appreciated
My son's car had this problem. The battery kept dying and he didn't know why. The blower would run at all times. I did a little research and found out about this. Replacing it was no easy task though...
Thanks for making the video, but how do you know if it's the resistor (final stage unit) or the capacitor? In my case (1997 328i) the blower motor no longer works, was working but had to keep it on at least on the lowest setting because if you turned it off it may not come on again. People with the capacitor issue usually had problems reading the climate control module. I guess I'll check the fuse first (pretty sure it's not) and then I'll change out to resistor since it's a lot easier to replace then to take the control module out to replace the capacitor which requires soldering out the old one out and the new one back in.
What year bmw is this... ? I have 2006 bmw 325xi.. video was helpful up to removing the glove box. blower motor is directly behind glove box. Cannot find resistor. Please help ANYONE?
Hi this is a very good video. I have gr8 1997 il my blower in the back is not working . what could be the problems .. Note the front is working good . thank you
Hello, I don't have any more power on my panel for AC and heating, should I go direct to change the FSU or first I should check the fuse and the relay? is there a relay for this to check? Thanks, for your reply.
Thank you for your very good video. I already ordered the part from Bavarian. A question: Is this replacement possible without pulling out the glove box frame? I saw some other instructions only taking out the under dash panel. Thanks
Okay, I replaced blower resistor, and everything is working good, but I have a problem. I could not fully snap in the part into the slot. It is not hanging out of the slot or anything, but the clip is not holding the part in as I couldn't get it inserted far enough that it would snap in. Will it cause any issues in the future?
Great video. I got a code with my Peake Research Scanner: code 06-8b (electric thermostat control final stage). I have read this is the same as "Final Stage Unit". Is this correct? I have no problems with air system, everything works fine. Any ideas? replace now or wait....Thanks.
Hi Bavarian, My 2003 x5 e53 rhd blower is intermittent. If I tap the top of my dash above the steering wheel it will work, only slightly but makes droning noises and sticking. Could it be the final stage resistor, or does it need a new fan motor ? Thanks Shaun
I have a 2002 530i and is draining power from the battery somewhere. I checked all the fuse and everything and no sign of leaking from them. someone suggested that my FSU might drain the battery but my ac and heater works fine. any ideas please before I go ahead and change the FSU?
The fan hasn't been working on my 2004 x5. I had fsu unit replaced 1 year ago so presumed it was that again. did it myself this time after watching your video. The last one wasn't quite fitting correctly, clip couldn't go on. replaced and fitted new one ok and clip fits . But fan not working?? what is the next step for diagnosing problem? can you help cheers Brendan
Likely, you need to replace the blower motor. Just make sure all the fuses are OK before you go into the blower. www.bavauto.com/shop.asp?HC1=0&Htarget=search.asp&HCY=2004&HCM=X3%203.0i&SearchStr=blower%20motor
Hi. At 4:48ish, would you happen to know where that clip with the purple wire and brown wire go to? I accidentally unclipped it from wherever it goes... Thank you!
I have a bmw x5 2009 48i and i could not find the location. I looked as per this video but its not there. Could someone tell me exactly the location for this particular model and year? thank you
Do I have the blower resistor on the same place on my car ? the blower on my car stops on works sometimes. I have a BMW E60 2004 Petrol from deutschland ???
Hello guys my 08plate x6 3.o diesel when I switch on air con it makes the ENGINE run rough any idea what it could be bmw agent's are no help what so ever,!!
I have a 2015 BMW X5 35i (F15). The driver side and the passenger side behind the driver ac does not blow cold air although will blow regular air. Even the passenger side also does not have a full blast of air once in Max AC. Should I be changing Final Stage Unit, Blower Motor and Blower Motor Resistor. I even don’t know the difference between all these different parts. Can someone help.
Hello bav, My ac blow just air (not cold) and if i switch the car off and on again. it might blow cold air normally and b4 15 mins, will blow hot air again. ive checked the compressor, its working fine. will changing the blower fix the problem?
Any helps or suggestion re this problem I'm having...X3 E83 2.0d - Blower blows on face and feet fine (hot, cold, AC) as soon as i switch it to windshield no air comes out of the windshield vents. Any help anyone?
No control in my 1997 m3 air conditioning. Seems not to have any control in speed of air. But if I have the setting on low and I'm on the freeway, it blows cold air (blows varied between how fast I am on the pedal) will this fix that problem? Seems I still get the hot and cold air, just not blowing ?
zack aglugub I have the same issue. My mechanic said its the blower about a $400-600 repair. So far we've only had a few heat waves and I've gotten by without a/c but it's nearly summer and I'm not sure I want to suffer in a hot box.. What did you end up doing?
I replaced my ac blower about a month ago and it never work ,is this final stage necessary for it to work ?? everything else is working , compressor and everything but it just doesn't blow any air ,

Hi i just brought a bmw e30 320i 1992 4 doors and its in a very very bad shape and i want to restore it, the thing is i dont know where to start from it would really help if you can guide. Like i said its a total mess
+ali elmir Well .... We would say to start with things that keep it from running, move to safety items, then on to whatever else is not working. Did you have any specific areas that are especially troublesome?
Would anybody be able to help me, I currently own a 2005 3.0L diesel x5. the issue is the engine temp really struggles to get hot on cold days and if i put the heater on it zaps all the heat out the engine. Now I know what you'll all be saying! change the thermostats, well done this, all of them but still no luck, I've even changed the Aux heater and had a new viscus cupelling on my engine fan and no joy. My local BMW dealer has looked several times with no luck has anybody heard of this before or know what I should look at next.
Watched another video and the mechanic said there's no need to remove the glovebox. I watched him replace the resistor without doing it. This video is too complicated
2strokemoto man If all the fuses are good, I believe replacing the blower motor is the next step. Which apparently requires removing the entire dash rather than just the junk box.
Hi BavAutorsport - Thanks for this great video. I got a question for you, if the Final Stage Unit is bad can this cause the electric radiator Fan not to move at all? First my Expansion Tank blew up. I replaced Expansion Tank and lower hose coolant Sensor. After replacing these parts I found out radiator fan moved sporadically, to the point only with AC on worked. After a while even with the AC on the radiator Fan wont move at all. It does sometimes, but not as frequent as used to be. Then it stopped moving at all. Second, the upper hose blew up. I replaced the upper hose and got a new fan since last scan shows signal reaching the Fan module but it does not do anything. Added coolant/did bleeding process. The Fan wont move when car reaches its temperature, I turned on the AC, it worked for a moment and then it stopped moving at all again. If AC is on air is not cold. If heater is on air is not hot. I appreciate your inputs and feedback. Car: 325i 2001 Thanks.
+Lauren Carver - Yes, similar. Your exact access will be different, but the general location is similar. The E36 Bentley Publishers repair manual would detail the exact access for the E36. www.bavauto.com/fland.asp?part=b398
Great Video! Watched it about three times before tackling it, went very smoothly and my blower is working perfectly again! Thank you very much.
Did this to me 1996 E39 5-series. It was a little cramped, but it worked like a charm. Thanks!
This helped me out a lot. One place said it was the blower and the entire dash would come out. Thank God I kept looking.

Hi BavAutorsport - Thanks for this great video.
I got a question for you, if the Final Stage Unit is bad can this cause the electric radiator Fan not to move at all?
First my Expansion Tank blew up. I replaced Expansion Tank and lower hose coolant Sensor. After replacing these parts I found out radiator fan moved sporadically, to the point only with AC on worked. After a while even with the AC on the radiator Fan wont move at all. It does sometimes, but not as frequent as used to be. Then it stopped moving at all.
Second, the upper hose blew up. I replaced the upper hose and got a new fan since last scan shows signal reaching the Fan module but it does not do anything. Added coolant/did bleeding process. The Fan wont move when car reaches its temperature, I turned on the AC, it worked for a moment and then it stopped moving at all again.
If AC is on air is not cold. If heater is on air is not hot.
I appreciate your inputs and feedback.
Car: 325i 2001
Thanks.
Are the hella fsu units of a decent quality. I think they are now Chinese built
The chinese fsu's on ebay worked perfectly fine for me
Would this work for a 97 328i?
+Lauren Carver - Yes, similar. Your exact access will be different, but the general location is similar. The E36 Bentley Publishers repair manual would detail the exact access for the E36.
