Amazed how simple of a job they've made this, i was expecting that i have to tear down the entire dash. Woke up to -15C and my heater not working today, not the greatest of times for mine to malfunction. Thank you, very straight to point video.

[@EXOVCDS]

I did this a while back. Removed the fan... washed in hot soapy water. Dried with hair dryer. Sprayed silone spray brown into the bearings. Held the blower in my hand. And connected it up. It got faster and faster I thought I was going to take off. Turned it off. Re-Fitted... Still hoping 3 years on...

[@riccardo8002]

Hi, thanks buddy. My blower motor stopped working 2 years ago and I was just about to remove the motor or if needed the dashboard to sort it out for once and for all. After watching this I turned the motor by hand from the engine bay and whalaaa... there she turns....saved me a bunch of time, frustration, money and scratches I would have gotten whilst removing stuff. Not too mention breaking clips and such. Thanks again for the video.

Thank you for watching! Nice to hear that one of my videos was of help to you!

[@MisterMasterDan]

Just tried this based on your comment and it worked! Did it fix it permanently for you?

[@johnwest8114]

I had the blower replaced a year ago and had a feeling it had just seized up ( yesterday ). Fixed it by removing the Pollen filter and giving the blower a spin with a fire poker. Then switched it on and it went like new. Then plenty of WD40. It took approximately 10 minutes. This was so easy to do I'll keep doing it every few months as a precaution. Thank you so much for this video. Liked and subscribed.

[@EXOVCDS]

After only 1 year... I would make sure that you don't have any water leaking into the blower motor intake, that could be causing the bearings to fail / seize up.

[@dvorakdj]

I really appreciate the troubleshooting before the replacement. I followed this procedure and found that my ground was bad where he dealer spliced the replacement connector during the recall. Cut out and replaced the butt connector and it works like a champ.

You can see yourself if the final connector is torched by carefully removing the aluminum heatsink and looking at the plug inside. It is the dealer should be replacing this and doing the work for free. It's under a recall of almost 700,000 vehicles. I believe it was August of 2017

Had same issue today just not BMW. Motor was not working so boss just ordered a new resistor which didn't fix the issue. I remembered this video and tried spinning it and it was hard to turn. New motor ordered, hopefully it gets fixed.

[@macvazehgoo5123]

I did take the blower out thanks to this video; otherwise I would have removed the dash which is a pain. Once the blower was out, I connected back to its power plug and see it working fine! so what could be the issue when It was sitting in its housing that was not spinning ? I have not yet tried to put it back to see if the issue is fixed; spins without pinky too but not as freely as the new one. Should I just lube it and put it back ? Thanks again for the great video you shared.

[@EXOVCDS]

Some people have had luck just using lube... since I am working for a shop, we can not just rely on lube.

[@michaelshone2465]

I was shocked at how easy that was to get at! Looks like it could have been a pricey little thing though...

[@EXOVCDS]

I'd have to check with the boss on cost.

[@EXOVCDS]

Don't know, sorry... original parts or cheap aftermarket? If you use the old resistor with the new motor... what happens? If you use the old motor with the new resistor... what happens?

[@gberbenkov]

I just sprayed the axle with some wd-40 and worked perfectly afterwards.

Nice... I can't take the chance of the customer coming back in 6 months to 3 years with the same problem, so a complete replacement is the best option for me / the service shop.

I did exactly that but when I was tighten the screws that hold it in place start making sound like the blades are hitting something so I left the screws as loose as possible and stop making that sound. Any suggestions?

What brad did you install? Did it come with the power output stage / control module?

[@EXOVCDS]

You can test "control" with a multimeter like i did... to verify power, ground and control signal. Did you? If everything is there, then the new motor / control module is bad.

[@cleyduarte2307]

hello friend, I have a problem similar to yours, can you help me, I tested the fan by connecting directly to the battery, it works, I tested the power cable It's ok, the controller thought it was bad because it wasn't passing energy to the fan, so I don't know? what do you think, thanks.

[@EXOVCDS]

Use a scan tool and check for fault codes in the climate control module... use the scan tool to perform output test / trigger the fan. If the controller is receiving a signal, then the controller is bad. If no signal is getting to the controller, then there might be a communication issue.

[@cleyduarte2307]

@@EXOVCDS thanks friend I looked at his programming and there is no error related to ventilation, this controller I bought a new one thinking it would be it and it didn't work anyway, I'm no electrical or mechanical professional but I tested the fuse I just don't know if this circuit ventilation has a relay. and also the bad thing that doesn't have that paper that says which fuse and the number I tested all the fuses one by one lol, but thanks for the tip, stay with God.

[@tinchos4400]

Hi...nice vid. I have a question. I tried to test the fan directly with 12v and the fan starts and stops 2 seconds later every time I do it. It's that normal. Thanks.

[@EXOVCDS]

I don't know, I have never tried it before. If the fan responds to direct power & ground... what does it do when attached to the "power output stage / controller"? Have you verified power & ground to the controller?

[@tinchos4400]

@@EXOVCDS Thanks for answering. The fan connected to 12v it starts and stops. The resistor recieves power but don't gives power to the fan. I have to replace it and start from there.

[@EXOVCDS]

Yes, do that.

[@Sal3600]

What's there voltages supposed to be from the resister into the motor?

[@EXOVCDS]

It's a pulse width operated motor / signal... I did not check the "control" signal, since the motor was stiff to turn. I'll measure the control voltage on the next one that I get my hands on.

Bmw recall in 2019 to replace blower motor in Ireland 😉😉😉

Not the blower motor, it was a recall to replace the blower motor harness. Check your recall and you'll see. They replaced mine aswell.

[@waterfordMARTIN]

@@Bruce_T u r right..my bad

[@120thevortex]

Hey man I've tried a combination of 3 different fans with 3 different FSRs. The car is sending 12v to them but no combination of fan and FSR seem to work. It's always the FSR not sending any power to the fan. I've scanned for codes and nothing stood out but I reset them anyway. I have tried testing with and without the engine running. I did even try swapping the fuse but still no luck. One of the fans is brand new. Any ideas?

[@EXOVCDS]

Year, make, model, engine? Overheating? When? Idle only or also when driving? Heat inside the car?

[@120thevortex]

2005 e91, 2.0 TDI. Engine can be off, idle or driving it doesn't make a difference. Before the fan failed the heating was very strong. All the blend doors and air recirculation work. The car isn't over heating at all. The fan stopped working a couple days ago. I know that the heater matrix is still getting hot because if I let my car idle for awhile I will eventually see the mist on the windshield slowly clear up to a point where the hot air is rising out of the top vents. I believe this is an issue relating to the PWM wire as no matter what the fan speed is set to the wire will give out zero volts.

[@EXOVCDS]

@@120thevortex sorry, I replied without reading the title of the video and assumed it was a radiator fan issue. Scanned for codes... climate control module or just obd codes? Yes, if it's not sending a PWM signal, the blower will not activate. I had an Audi recently where there was no communication between the instrument cluster and the climate control module, resulting in an inoperative climate control module. I don't know much about BMW's / if output tests / activations can be done with a scan tool. If yes, see what happens.

[@120thevortex]

@@EXOVCDS I did scan for codes and found several relating to the air temp blend doors but I am certain mine are working, this alone should not hinder the operation of the fan from what I've read. I did also find some strange CAS codes such as a speed signal sensor fault. I did clear them all but they came back. I'm going to be ordering some software that will allow me to operate output tests and take better readings but until then I will be without heating.

[@faradaysage15]

we'll go ahead and save everybody an assload of money right now by reminding you there is a recall on this for the wiring harness. If your wiring harness is all burned up like mine and your final resistor pack is also torched, the dealer should be replacing all of it for free and doing the work.

[@EXOVCDS]

@@resinmag4202 I would replace the motor (and power output stage) if the motor was stiff. I don't think that they can be taken apart easily for overhauling (replacing bearings and motor brushes). The time & effort trying to fix it, can end up costing more than replacing it with a new unit.

My biggest complaint about BMW is their devotion to pretending that there is nothing making the car work other than the car itself. Lift the hood, the engine is completely obscured by covers. So are all the hoses, and the suspension... No battery, either! It's in the trunk (usually), but you have to remove a bunch of covers to get to it. No fuse panel; gotta remove a bunch of panels to get to it. The hood release lever is often unmarked and tucked up under the dash... BMW is doing everything they can to make their customers think there are no parts and nothing to go wrong! Bloody annoying...

[@EXOVCDS]

So true!

[@superpeluso1]

I think that my 2007 328i is easy to work on. Sure it has lots of insulation plastics but they’re quality vehicles!!! My trusty old bmw still runs like new

[@EXOVCDS]

My 27 & 29 year old BMW's run just fine as well. Have you had to change your starter yet? Should be a simple job on most cars... I know it is on mine. Things are different these days (anything after 2000), that's all we're saying... and it's true that "different" can be annoying.
