How Automobiles Work

Hello and welcome! Today I will show you how you can check,
clean or replace the heating blower motor in a VW Polo 2003
9N. The motor for the heating and cooling inside
the car started to make a loud noise. The noise is different at
different speeds On speed 2, you cannot really hear it here
but the noise was there and it was also vibrating The worst was on 3’rd speed and 4’Th speed. The first thing to check is
the air cabin filter which is under the passenger side. You open… there are 2 brackets. You remove the brackets and then you slide
the cover out. And then the filter is inside, you just
pull it down gently. As you can see, it’s full of leaves and dust
and it’s very dirty. At this point you can replace the filter or
if you want to try to clean it you can wash the filter and keep it to dry
for a few days. You can wash the filter with normal detergent
used for clothes. There was a lot of dust and a lot of leaves
in the filter area so what I’m thinking is that I need to clean
the motor first. Will try to clean it before replacing it. After removing the filter,
the noise is not so loud now for third speed. Fourth speed is still pretty bad now. The second speed sounds better
but the vibrations are still there. To remove the blower motor you first have
to locate the screws… there are 3 screws here. To open these you need a torx screwdriver. Then you just remove… you slide this cover
upwards and don’t remove it completely just…
let it hang like this. Just enough so you can access the next 3 screws
that you need to unfasten. These are the same type of screw but
it’s a smaller size than the previous one. You remove all 3. The next step is to remove the screws that
hold the glove box in place There is one in the middle They are also torx screws. There are 2 on the sides. There is one and the other one is there. After you remove all 3 screws, you will pull downwards and push at the
same time and then slide it towards you… like so. And just be careful, on the left side
there is the gear mechanism for the glove box opening system. Be careful not to damage that one. Then just set the glovebox aside,
keep it somewhere away from your work area. And now, behind the glovebox there is the
motor. It has 7 screws. Here I’m trying to show you the screws. You just have to find the golden ones
they’re shiny compared to the other screws around them. These are made in a different way so…
just make sure you find all 7 of them and then
you open the motor. After you remove all screws,
disconnect the electrical connectors and the harness
as you see here. You also need to remove the second part of
the harness from the motor completely. It should be like that. And then just pull it out, being careful
not to damage the connectors and the wires. You will pull it out slightly and then slide
it downwards to remove it from the car. This is how it looked like when I took it
from the car. It wasn’t really dusty actually. And it spins freely. I will clean this motor from dust as much
as possible especially inside, where you see the parts. I didn’t have compressed air but blowing the
air out seems to work pretty much for me. The motor spins freely without any noise. I also cleaned the place where the motor was
sitting. Just trying to remove any dust from there. Here on the right, you can see the fuse the thermal fuse that is used for the motor. If your motor is working only on the fourth
speed and not on 1,2,3 then this fuse is blown and it will
need to be replaced. It’s accessible from the top there as you
can see. You can get a special fuse for this and then
just crimp it in there and it will work. This would happen if the motor is consuming
too much power… too much current and
it’s a protection mechanism. I will put the old motor back after cleaning
it but you could just replace it… use a new one. The process is the same.. reversed just
make sure that here it’s aligned properly with the rest of the components. It has to be a tight fit just like that. And you make sure that you re-place all the
screws and test it before you put everything back. The noise is still there but actually…
after driving a few days it became less and less each day. The most noise I have now is on the third
speed. On the first speed it’s completely noise free. If you found this video helpful, Please give it a big thumbs up! And subscribe to my channel!

  1. 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. 😅

  2. 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????

  4. 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.

  5. 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.
