VW Polo 9N Heater - Noisy Blower Motor Replacement or Cleaning

Heather blower(HVAC) motor was making lout noise at speed 2, 3 and 4. Visit: www.ionhowto.com/vw-polo-2003...
While the blower motor was running the dashboard was vibrating because of it.
Showing how to remove it from the car, and clean it.
If the noise is still present you can replace the motor but i's worth trying to clean it before doing that.
Also showing the thermal fuse of the blower motor.
If this fuse is blown, your ventilation will work only on speed 4. On the other speeds the motor will be off.
That thermal fuse can be blown if the motor is really going bad and doesn't sping freely, thus consuming more power(drawing more current).
That fuse is a safety measure, replace it if needed with the same specification. DO NOT replace it with a plain wire!!
If you have any questions please feel free to ask in the comments section bellow. I will answer them as soon as I can.

If your polo has an intact cup holder you are a legend

[@IONHowTo]

It's not intact at all. A leg is missing and the cover. That thing is probably the first to break in these cars haha

[@rogerbloye3581]

Thank you for a very clear and informative film

[@RA-pj2tf]

And again bravo!! Very clear explaining!

[@IONHowTo]

Thank you! 👻

[@NoiramK]

Thanks for the instructions! The mechanic wanted €500 to do this over here in Norway, money well saved. Multumesc!

[@IONHowTo]

Wow! Cu placere!

[@srinivaskumarreddy120]

Very informative Mr. ion🙏. From🇮🇳

[@thembinkosimqakanya8067]

Thanks this helped, my motor was making noise only to find out plastic was stucked inside

[@mav3rick25]

Thanks for the video!

[@kevinclark9513]

Thanks for this. Well laid out and very helpful! I also saw your advice about replacing with a new motor rather than a used one if replacement required. Thanks again.

[@IONHowTo]

Thanks Kevin! 😀 A used motor is what I chose the first time and had to replace it again after about 1-2 years.

[@haridarling5093]

Olo O L O Oom

[@HamzahVerster]

Great video. Helped a lot! Thank you very much

[@IONHowTo]

Thanks for the nice comment! :)

[@dzejunio78]

Nice video!!! Bravo

[@j.s1287]

Thank you very much for this tutorial sir. It is explained step by step, easy to understand. Thanks to your information I was able to replace the (20 year old) original one with a new one. Center bolt was rusty which explained the high pitch squeaking sound. Keep up the good work! Kind regards!

[@IONHowTo]

Thanks for watching!

[@michaelmiklosofficial]

Its helps to replace the heater resistor too. This is a good video

[@Slaygee]

Thank you for the video!

[@sega-studios]

thank you mate it was helpful

[@WassimBM]

Thank you for this video :)

[@IONHowTo]

Wassim BM thanks for the nice comment :)

[@Barnzy213]

Great video mate. I need to replace the recirculation flap motor. Could you explain how i would do that please?

[@IONHowTo]

6 not 7 screws need to be removed to take the motor out. There are 2 screws on the left are for the air recirculation flap control motor. That doesn't need to be removed. 6 screws, sorry for the mistake. 😅

[@TheFlorinc70]

Very good!

[@pokojnaziemi7679]

Bardzo ale to bardzo dziękuję za Film ! Wentylator wymieniony ! Koszt w Polsce firmy Polcar 100 zł.

[@medbeng4905]

Thanks

[@damiennaidoo4031]

I need to know where the cable connects to change from hot to cold. My cable came off and I need to put it back.

[@crashingkite]

Thank you for a very instructive video. I was wondering however, if you could get access to the blower motor bearing, and given it some oil or WD 40, wouldn’t that have helped to eliminate the noise? I have a squeaky blower and was thinking this might help. I have not taken the blower off yet.

[@IONHowTo]

You could try it but soon you'll open it again. :)

[@pst206cc]

good 👍

[@osmanarikok4412]

Thank you so much

[@IONHowTo]

Glad it helps! Thank you for such a nice comment! :)

[@MrStoopio]

Awesome video man! Really kind of you to share your knowledge. I have a problem with my polo 9n from 2007. Only on the coldest temperature it is blowing cold air... When I turn it 1 small bit it immediately get's hot. Do you know what it possibly can be????

[@IONHowTo]

I had a similar problem. Safest thing is to get a ODB2 scanner - vag com. If you have any codes related to the the v68 motor, thats it. There’s a potentiometer in the v68 that can be cleaned with contact cleaner. I cleaned it a few times with contact cleaner spray then tried to clean it with wd40 and it’s been great for a long time. Wd40 keeps it good longer than the other stuff. Just do it slowly and don’t bend the metal contacts on it. Carbon dirt gathers on it and confuses the ECU about where the motor is positioned. Then it goes crazy going hot or cold on its own. When cleaning mine, I didn’t record it... it was a long time ago. Search for vw polo v68 motor potentiometer cleaning. ODB scanner is the way 😅

[@MrStoopio]

Thanks for the quick responding. I'm gonna try to fix this because it's getting annoying;)

[@kasparsfreimanis4196]

Thanks..

[@NathanTEG]

Awesome. Mine was small plastic bag that got sucked up. Now i've just realised i didn't replug the glovebox vent. ohh well.

[@issydegirmenci7332]

hi ty fr the video i have a problem with the heater it blows with max heat or max cold , and somtimes when u have AC on cold it changes to max hot

[@IONHowTo]

Theres a potentiometer near the recirculator flap. WD40 in that fixes it but you have to take it out first and its not very easy.

[@trebaxttv]

Great Video, amazing explanation! Thanks a lot man. I have a bad smell problem when the heater is on. But no smell when AC is on at cold. I already replaced the cabin filter but didn’t help at all. Do you think this will help? Or it’s something else?

[@IONHowTo]

Could be that there was some animal in the vents. Usually the smell is from running ac on cold not the heater and it smells like mold for a few minutes if you didn't stop the ac before stopping the car

[@rossendyakov9326]

Hi. Removing this fan seems to be like piece of a cake but I could not do it. After 2 hours battle I succeeded to unscrew one of all 7 screws only. Could you please explain to the beginner how exactly to reach each of the 7 screws. Thanks in advance.

[@IONHowTo]

It's not easy but it can be done. Use both a long 15-20cm screwdriver and a short one 5-10cm. I think I've shown the number of screws but to record unscrewing them would be almost impossible. Maybe I could have done it but didn't want to spend 5h sweating on the thing. Most important is to remove the glove box and pull that tray a bit - no need to remove just the screws. A thin small but powerfull work light or even a mobile light is a must. First use the light to locate all screws, you can gently pull the fluffy insulation back but don't apply pressure around the AIRBAG! Anything with the YELLOW color, treat it like fragile egg shells. Yellow is danger - the airbag unit and wires. Your head goes where feet usually go and try to use long or short screwdriver depending on each screw. Use screwdrivers made from one piece, not with interchangeable bits. Hope you can do it.

[@lidge1994]

Seems like it went silent when you pressed it in the right place, maybe a loose mounting spot makes the motor unbalanced and it vibrates?

[@iam_mk1]

i have 9n 2006, ac blower makes noise at level 3 and 4,when put wd-40 the noise reduced to some point. But i could hear like the motor touches somewhere when stopping the car. The chances are loose mounting or unbalanced rotation..is there anything i can do before getting a new one?

[@jepic7071]

Hi did the problem go away! Or did you replace the motor

[@IONHowTo]

Jay Yaqoob I cleaned it. Was really full of dust. It didn't really go away it just became less noisy on speed 2. Speed 1 has no noise at all. Since then, I purchased a new blower motor and will install it when I'm in the mood :) sooner if it becomes more noisy again. The new blower motor sits in the box until then. I've changed this motor before with a used one. In conclusion, when it's noisy, replace it with a new motor not a used one. 😅 Will make a short video with the old vs new motor eventually.

[@ahmetelma1321]

Where is the heating core in this car?Heating is not enough in my car.I am planning to check it.

[@IONHowTo]

Made a video but it's not finished and uploaded yet. Heater core behind engine 2 hoses go in firewall. It's behind the dashboard deep within. I wouldn't remove it but flush the hoses back and forward with water to clean them.

[@orhanabd1724]

Ai montat motorașul nou?

[@orhanabd1724]

Schimbă si tu mai des filtrul de polen! În ce țară esti? Si al.mey face zgomot când e frig afară.

[@Dr._Spamy]

Is it better than before ? And what was the fix ?

[@IONHowTo]

Did you watch the video?

[@Vuokko]

I have VW polo -06 and tried to do this, but the interior is built differently. Got the glove box off easily, but then there were a lot more wires and beams that aren't there in older Polos. So didn't succeed this time, maybe I have to give it another shot later 🫣 The noice coming from the fan is killing me tho 😂

[@IONHowTo]

Yeah it's annoying

[@issydegirmenci7332]

did replace the copressor but no change

[@IONHowTo]

Ouch, replacing the ac compressor for that is a bit too much. Better scan the car with an obd2 tool on the hvac system and it should have errors related to the flap position intermittent or similar.

[@anis7399]

Why didn t you tried to lubricate the motor? It could help

[@IONHowTo]

It's hard to get the motor out and its dusty in there. You don't want to do this every year.

[@marcillinoryneveld6378]

I replaced blower heater resister but still not getting hot

[@marcillinoryneveld6378]

it just blows cold

[@IONHowTo]

@@marcillinoryneveld6378 the resistor is for the motor to work on speed 1-3, when that fuse is blown, motor works only on speed 4. Your problem sounds like the recirculation clap motor, make a video recently with that. Find it in the car playlist

[@elkurdo10]

I have question, Mine blows only warm air. What's the problem?

[@IONHowTo]

Motor position potentiometer near the air recirculator flap.

[@damiennaidoo4031]

Mine only blows cold.
