In this video I have this Mercedes B class w245 and I will be replacing the blower fan as it keep blowing the resistor that controls the fan.
The fan has developed a some sort of resistance when turning and as a result it blows the resistor after a few days of use.

Likewise mine didn't have the retaining screw either. It's a complete pain to take apart but couldn't have done it without your video, many thanks.

[@DaringBeefcake]

Your very welcome, it is a pain but at least we can get it going again hopefully for a long time.

[@interceptordave]

I want to thank you for making this video, it has been very helpful - especially the comments. I've replaced two blower fans and two resistor packs in my 2007 w169 A150 over the last three years. The first pack and fan died due to water in the cabin filter housing, no idea why this latest fan died. Great cars, rubbish heaters!

[@DaringBeefcake]

You welcome, and thanks for the comment, yeah great cars but the heater blower location not the greatest.

[@artickatk4853]

Great video again. Who needs 2 hands when you can replace the blower with one hand, hehe. Good job dude and thanks for sharing. Keep up the good job. Greetings from Spain.

[@DaringBeefcake]

Thanks 👍,yes am glad am getting an extra skill using one hand 😂

[@jonathanhopper9020]

Thanks for sharing this video. Just changed both the blower fan and resistor. Great video showing how to remove and put back.

[@DaringBeefcake]

Fantastic well done glad the vid helped :)

[@david.thomas.108]

Thanks again for this video. I was able to change my stuck blower fan myself. I have the automatic type aircon so the fan was slightly different. It has a resistor component built into it. Not a separate resistor piece like this one. Otherwise very similar. It was a mission to carefully reassemble the new fan inside the confined space but did it and it works! Some other tips, there are some slots for the screw holes to align between fan and cover and the screw were torx T10 type.

[@DaringBeefcake]

great thank you for sharing your experience, it for sure be useful to someone, including me of course :)

[@sarahjackman1494]

Amazing video that allowed me, a complete novice, to change the blower and get it working again. Thank you

[@DaringBeefcake]

You made my day with this comment, so glad to hear it was helpful,gives me will to keep making vids and helping everyone out there specially in this difficult times.. God bless.

[@bazzar4283]

Greetings! Had a replacement fitted 24 months ago by a local garage £550. Has packed up again so going to fit a replacement myself using your tutorial. The New fan and Resistor cost £60! Will let you know if I am successful. From UK

[@DaringBeefcake]

It can be fiddly and you might swear a lot, but it is doable, I've done 3 so far of course the first one is always the learning one. Let me know, wish you luck, patients is key.

[@gregmccullum1000]

Thank you for taking the time to do this video. Much appreciated 😊

[@DaringBeefcake]

You are so welcome!

[@howtodiy2220]

Thanks for the video , it's very hard to reach up there under the dash , it will take me at least half day to change the fan blower motor

[@DaringBeefcake]

I hope it goes well :)

[@dirtyharry20000]

Thanks a lot. Just completed that task. Important is really to remove the glove compartment. And reassembling of motor + cover needs a bit patience. Rest is pretty easy.

[@DaringBeefcake]

Great 👍

[@AndyWWW]

Also check this. There is a drain hole below the cabin filter. If it blocks then water enters the heater air input and can short out the ballast resistor and fill the battery compartment with water. Eventually the battery will short also. I used a trombone brush/snake to clear the drain pipe after removing the filter.

[@DaringBeefcake]

Yes thats a very good tip to give here, I have seen that happen to a few a classes as well need to clean the pollen filter/cabin filter drain hole, to avoid water going into the resistor and the fan motor.

[@basbassie7360]

Had this to mine now😢

[@david.thomas.108]

Very clearly explained and helpful video thanks!

[@DaringBeefcake]

You welcome 🙏

[@magnanic]

GREAT video and HUGE patiente!

[@DaringBeefcake]

Thank you very much!

[@bricoes3byjose869]

Very good job 👏🏼

[@DaringBeefcake]

Thanks

[@danparvu3109]

Thank you mate....really nice video and explanation...made my day easier and cheaper ( LOL ) ...really appreciate....keep going 👍👍👍👍👍

[@danparvu3109]

My problem was that , even though the resistor is half year new , the motor works on and off...I have to bang it with a hammer, or something to start working again...my belief it it the motor itself as , when is working all the 5 grades of the fan are working....this , maybe useful for others....cheers

[@DaringBeefcake]

Yes you may need to change the motor blower eventually. Thanks for sharing your experience.

[@DarkSphinxx]

THANK YOU FOR MAKING THIS VIDEO IT HELPED ME

[@DaringBeefcake]

You're welcome!

[@leandromoretto9187]

Graciaaaaaaaaaas!!! Thanks

[@nh3538]

Thanks, I had no replacement yet so for a short-term fix I used WD-40 on the bearings, seems to have helped for now, but guess I'll need to replace it soon anyway.

[@DaringBeefcake]

Yes you’ll need a new one at some point.

[@mattbfpv7172]

Just bought a resistor. My plan is to change it out and see if it lasts. I will only change the blower if the resistor fails again.

[@DaringBeefcake]

yes of course usually changing the resistor is enough.. but occasionally the motor fails..

[@yt1vpb]

Thank you!

[@DaringBeefcake]

You're welcome!

[@akiaro_com]

Thank you for the video. In my car the steering wheel is on the left side. Can you advise on which side to replace the fan in this case?

[@DaringBeefcake]

well its easy enough to check if the resistor is in the same side as the vid, and if it is then it more likely be that its the same arrangement. hope this helps.

[@nh3538]

Just for future reference, I have a leftie too and the setup is the same, but the right side is the passenger seat, so the other parts look a bit different (e.g. no steering wheel ;)) but the method worked like a charm.

[@DevSubramaniam]

Fantastic... tqvm it has been helpful

[@DaringBeefcake]

Glad to hear that

[@nodrinkingproblemhere9095]

I simply removed floor cover altogether. I hate fiddling. Took under hour to remove everything.

[@DaringBeefcake]

Brilliant thanks for the tip for anyone who may take a different approach

[@tangomike15]

Is yours right hand drive? Do you mean just the floor cover at the drivers seat area?

[@jt2186]

I tried this and like people mentioned it took ages to get the fan motor to mate with the plastic housing.When I turned it on it doesn't work on setting 1, but does on 2-5.Also it sounds a lot louder, like a vacuum cleaner! Is it possible to connect the plastic housing to the wrong set of holes on the motor?

[@DaringBeefcake]

Well it sounds like the motor is under some kind of resistance , something touching it or its at an angle, yeas the holes need to match otherwise the wires would be in the wrong place. I don't think you can fit it to the wrong set of holes but it might not be sitting properly or you have a faulty new fan.

[@matthewrowlands7271]

Hi there, we have a 2008 B-Class (b200) and the resistor is not in that location? seems to just be a plastic plug there. Do you know where else it may be located? TIA

[@DaringBeefcake]

That is a bit odd unless the vehicle has been modified that year.

[@efsane-6181]

I have the same problem in my B200 turbo. Did you find the place of the resistor?

[@user-ly8vd8mv2r]

Changed the resistor and it blew again. Will change the fan and try again!

[@DaringBeefcake]

Good luck , hopefully it will work well for you.

[@darstellar]

I can tell you now, having just done it, that it's a pain in the arse to get it back in and lined up! After much swearing and jiggling around it's done. Set aside some time for this!

[@DaringBeefcake]

I agree it’s a pain the butt. No doubt about that, well done for doing it though, and hopefully you saved yourself some labour charges or someone saying the whole dash has to come out 👍.

[@iancourtney2041]

I changed my blower motor today....what a b#stard of a job to reconnect the two parts of back together! This job must be a cinch on left hand drive models, as you only would remove glove box to gain loads of room!

[@xhsxspectre]

Did it on a left hand drive. Lemme tell you, its still a pain in the butt. ​@@iancourtney2041

[@sedatkocak4606]

Is the blower on a left hand drive a class car on the same place ?

[@DaringBeefcake]

I would think it is.

[@Soso-e59]

Bonjour j'ai un souci avec ma soufflerie elle ne fonctionne pas du tout 1 2 3 4 rien du tout sur 5 rien non plus mais sur 5 le fusible pète.... Pensez-vous que ce soit le moteur ou le fusible merci d'avance ???

[@DaringBeefcake]

It is very common for the motor to fail and make the resistor or fuse blow. So I would think is more to do with the motor.

[@TheRazvancristian]

Hy mate,i have same model of mercedes..a 2 months ago heating work without problems,when i comeback from holliday heating dont have power like before..come a little warm air inside the car but not like before,when was winter in 2 minute was warm in the car..you know whta can be the problem?

[@deebhavsar9282]

Hi I’m having the same problem. The heater is blowing warmish air but not hot like it used to. So in winter time the car is still cold 🥶 it’s just warm air but not hot enough. Did you manage to find out what the problem was?

[@TheRazvancristian]

@@deebhavsar9282 no unfortunately..someone told me is heating blower problem,but i dont know...i need to do mine too as my girlfriend is pregnant and that's not good for her when is in the car because she drive the car

[@deebhavsar9282]

@@TheRazvancristian thank you for your reply last thing I want to do is take it to my mechanic at the moment 🤦🏽‍♀️ but if I figure it out I’ll post it on here for you to 👍🏽

[@TheRazvancristian]

@@deebhavsar9282 ok.thank you

[@TheBlibo]

Hi Great vid very informative but I couldn't remove the cover from the motor it seamed to be stuck. my cover has the white rubber inserts around the cover screws, I ended up disconnecting the stearing colomb and that gave enough room to alow the motor and cover to come out Hope this helps someone

[@DaringBeefcake]

Sure it helps, thanks for adding info, very much appreciated.

[@tangomike15]

Thank you. I will have to try that. The pirate part fan I bought is slightly different to the original part. Instead of threaded holes built into the fan, the two parts are held together by bolts and nuts. As it’s impossible to hold the nuts on the other side while screwing in the bolts, I can’t use the method shown in this video, although I did use this method to remove the old one. I will try the steering column method.

[@leandromoretto9187]

I Will try

[@DaringBeefcake]

De nada, you welcome 🙏

[@jpsion]

did you disconnect the battery before the install?

[@DaringBeefcake]

No I didn’t.

[@Gr3eGo]

Car is good, but this fan system is terrible.

[@DaringBeefcake]

It isn’t great, it’s the pollen filter that usually gets wet and allows water to get into the area. Make sure you check you pollen filter and that the area is not full of dirt, also that the cover is properly closed.

[@Gr3eGo]

@@DaringBeefcake Yes it is true all that you mentioned. In my case fan was worn out, magnetic dust from wear of 15 years increased fan resistance, and pre resistor was very hot all the time. Replacing this fan is very difficult regarding its terrible position...

[@DaringBeefcake]

@@Gr3eGo yes it’s a pain, hopefully it last a long time now. The way the fan fit is not great.
