Blower Fan Problem - Not Working On Speeds 1,2,3 (Seat Leon 1m / Toledo 2)
Вставка
- Опубліковано 29 сер 2016
- Is your blower fan working only on the 4th speed?
This is a common problem for this generation of Volkswagen-Audi-Group cars.
You need a new resistor block, or just the thermal fuse.
For this car you need a 192°C, 250V, 10A thermal fuse.
Resistor block serial number: 1j0819022a
If you have the same problem on your Vw Golf 4 / Bora / Skoda Octavia 1, the repairing method is similar. You need to dismantle the dashboard to reach the blower fan and fan resistor.

EXCELLENT tutorial of the soldering !!! The bends, the cooling protection, this is how a PRO works. Your are a technician with brains.. Rare on youtube.
You just saved me a ton of money...my 6R polo just started with this problem on the hottest time of the year.
Used your video to access my blower fan and a piece of floppy plastic sheet fell out, and now my fan is back to normal. Thanks.
You the MAN Sorin!!! Thanks for an excellent demonstration - I'm on it!!
Thank you so much..today we fixed my leon with my friend thanks to your video😄
Greetings from Mexico, excellent video, you should upload more videos, I have a Leon 1 seat and there is no information regarding this versatile car, especially in reference to the turbo. Thanks and slds
thanks! Mike 2010 vw passat cc, I figured it would be much harder than that! saved me 2 hr shop rate! ($100-$120/Hr CDN)
just had this problem last week(israel-seat leon m1 stella 2005)
one of the fan cable connectors to the ressistor got burend really bad all the way through the plastic connection plus it had alot of rust and corrosion there too.
i dont know what i would do without you sorin
thank you so much for the detailed guide!!
ressistor serial number 1j0819022a
the 4 pin connector to the ressitor serial number 1j0 972 754
if any body will need to order them too (:
hi. thanks for the info. I've seen this problem before. the pins of the resistor block rust due to the air humidity, or water gets in the fan compartment. the corrosion creates an imperfect connection between the pins and the wires connector. this imperfect connection becomes a resistor to the whole circuit and gets very hot because there is a lot of amps going through these wires, then the wires get hot too. this is very dangerous, because the wires insulation melts and the wires can melt other plastics too.
Verry good tutorial
Hi,thanks for a video.you helped me so much.repair cost 55e cnt
Excellent thanks just the job and video is so clear with good explanations. I like the tip about the water!
Ești cel mai tare Sorine
Thanks for the tutorial. In my case I had to use a screwdriver instead of the 6mm wrench.
Hi. Thanks for the feedback. There is probably a difference between the models. Mine is a 2003 model.
Thanks a lot, it was very helpful !
Good one Sorin, be careful that soldering iron might go off accidentally
one of the best videos on YT:)
Dacă vorbești românește înțelegem și noi
Hi Sorin, your videos helped me save €€€€ multumesc mult. :)
bravo, multumesc, am invatat ceva nou si am sa schimb "thermal fuse" :)
ms
Buna treaba Sorin.
M-a amuzat teribil cand te-ai enervat cu surubul ala :-).
PS: mai bine schimbai cu totul rezistenta aeroterma e 30 de lei, bine a ta era originala dar are o varsta..zic si eu
salut. in cazul acestui tutorial blocul de rezistente e bun, nu are rost sa fie schimbat. s-a ars doar siguranta termica, pretul acestei sigurante e doar 5 lei. trebuie doar putina indemanare pentru lipirea sigurantei pe blocul de rezistente.
good job man!
Hi thanks U show me the way so my car vw Sharan 1.9tdi 2000 blower 1, 2 not function 3,4 fuse ok so Dear where can find this part. thanks to inform me.
Great video!
sorin do you have video to replace heater from this leon??
very helpful thank.s
Thank you!
Hi I have problem that fan did not blow warm air to salon, what should I do?
Exelent test frend
For golf mk4 is the same process?
Good night my friend and nice to meet you!
I have a (2003 DODGE CARAVAN SE) and im trying to apply this but i dont understand how to do it (Check for continuity between each of the blower motor switch input terminals of the blower motor resistor and the resistor output terminal)
Are you able to please make a video showing me how to do that properly and safely?
I will greatly appreciate your help.
You have a good night rest my friend! 🙏
EN: Very nice well done video, the problem is clear and also the solution. I have a Sharan from 2006, but it has a kind of transistor in a red box, instead of green resistor and thermal fuser. What do I need to do in order to make the blowing fan work again? Is it a commun known problem like this?
RO: Foarte fain, bine facut video-ul, e foarte clar care e problema si ce trebuie facut. Eu am un Sharan cu ceva tranzistor, intr-o cutie rosie, nu are rezistenata aia. Ai idee ce sa ii fac sa invarta iarasi motorul? Adica e vreo problema comuna cunoscuta, precum cea cu siguranta asta?
thanks Sorin
Termal Fuse 192˚C a resistor is from wire wrapped around resistor case. Probbably if first (first resistor from wire) blow its possible to make new from copper wire
Salut, ai idee unde mai poate fii rezistenta? La mine a fost acelasi capac fara rezistenta/mufa in ea. Nu am vazut nici-o alta mufa sa fie pe acolo sa ma duca la rezistenta. E diferit la cele cu climatronic ?
That happends to me on my Audi A3 8L1 1997 1.9TDI AGR , and ordered the whole piece for 11€ new like a week ago and i hope it fixes it
I have the same problem on my Laguna 2 from 2003,just notice this problem,I will do the same,thanks for the tutorial,excellent video
What type of thermal fuse I need? Thanks in advance
hi. the fuse is different for every car model. For my car I need a 192°C, 250V, 10A thermal fuse.
Multumesc mult pentru video, mi-a fost de mare ajutor! Am schimbat rezistenta la un Toledo din 2006... a fost aproximativ la fel... am curatat si aeroterma!!! Super!!!
Acum dupa aprox. 2 luni de la ”reparatie” nu mai vrea sa mai mearga pe tr. 1 si 2... am inlocuit inca odata rezistenta (crezand ca s-a ars iar) si nimic... ai vre-o idee?
Multumesc anticipat!
salut. blocul de rezistente are 4 pini. 3 pini sunt pentru treptele 1, 2 si 3 ale ventilatorului. ori nu mai fac contact cei 2 pini, poate au oxidat. ori s-a ars una din rezistente. ar trebui sa verifici cu un aparat de masura pinii blocului de rezistente. unul din pinii din capat (nu mai stiu daca stanga sau dreapta) trebuie sa indice o rezistenta cu ceilalti 3 pini. daca nu indica o rezistenta cu cel putin unul din ceilalti 3 pini (probabil al 3lea) inseamna ca e arsa una din rezistente. si nu ma refer la siguranta termica din capat. ma refer la rezistente facute din bobine si acoperite cu acel material ceramic verde. daca rezistentele si pinii sunt ok, inseamna ca se blocheaza ventilatorul la turatii mici. vezi daca se invarte usor cu mana.
Where is it on a SKODA PICKUP -98?
Just seen this video. Ok on changing the fan - BUT - dipping the component in water to cool and then using a mains powered non-polarised non-earthed soldering iron is a sure fire way to get electrocuted! Use a proper clip on heat sink and low melt point solder and a proper electrical soldering iron instead! Looping the component wires will have little effect on protecting the component temperature-wise on soldering - unless you loop about three times and use a heat sink clip! If you solder properly the melt and solder apply and set should be completed in less than 1 second and that will not damage the components.
Excellent! Was the video edited or did it take just 12 minutes to do the job?
hi. the job takes longer time. I've edited the video, to show only the important parts.
Great!

Salutare ,ceva problema asemănătoare am si eu la o jetta 2008 ,pe siguranta scrie 240 kr1 ,să fie la fel ca si a ta ?
Hello, my name is Toros, I love your UA-cam channel, I really like that you explain everything so well. I have a question for you, I have a Seat Ibica, born in 2006, but the EPC and engine control lights are always on. Sometimes my engine runs in emergency mode, why? Can you please help me. Thank you in advance
Hello Sorin, i Have 2002 Seat Leon. My blower works fine, i have clima, but in 20-30 kilometers my fuse just blows (in the fuse box) where could be the problem ?
hi. probably the climate control uses more Amps than it should. It could be a short circuit in the system. Only at a service they can check that. Try to manually set the blower fan at different speeds, see if that changes anything... and check if you have the right fuse, I've found that the fuse should be of 7.5 A.
We have a 2010 Volkswagen Golf wagon and when our blower fan speed is on number 0 the fan is still blowing air in the cab. Doesn’t turn off
Under mine blower there is no this thing with transistor. BLOWER ISNT WORKING , I bought another one, but still same. What could you advice?
Dacă scoți mufa de la airbag nu îți dă eroare în bord.? Operațiunea ai efectuat-o cu borna scoasă?
OARE AI UN VIDEO CU inlocuire radiator habitaclu? la seat leonul tau?
Thanks for the video, helped a lot! However mine has blown again... what do I do?
that means you have a problem with the blower fan motor. take it out and spin it, probably it will spin very little and it's jamming at lower speeds. clean the motor bearings with an electrical contact cleaner spray. then use some WD40 or other lubricant on the bearings. it should spin much easier. if the blower fan motor is spinning slower than it should, or it's jamming at lower speeds, the motor current consumption is increasing, the fuse will get hotter and will blow again. after cleaning the blower fan and replacing the thermal fuse, avoid using the first fan speed. these are the main reasons the fuse burns.
Sorin - DIY Mechanical Nerd I haven't tried this yet, but it looks like amazing advice. Very logical when you think of it.
Thank you so much. I'll like and support your videos as much as I can.
The motor bearings are sealed so it is very difficult to re-lubricate them. Also WD40 is not a lubricant it is a rust preventative. My suspicion looking at the motor I have just replaced due to it blowing the 40 Amp fuse on high speed is that the strength of the permanent magnets weakens with age and this results in a higher motor current and therefore results in the fuse blowing or possibly the motor resistor overheating. Note the airflow from the fan cools the heater resistor so if the airflow reduces either due to reduced efficiency of the motor or blockage of the filter or elsewhere the resistor will overheat and probably blow the thermal fuse.
Hi it is great repairing video,i have a same problem, homever i noticed my air con light only comes on, in the 1. speed setting, the 2&3 and 4 speeds the air con lights switches off,not blowing cold air. any advice what could be wrong?
hi. I never heard of this problem before. I think it's a problem with the fan speed knob circuit. you need an auto electrician with a multimeter to check the connections.
thank you for the advice i will get it checked.
I have the same problem, did you solve it ?
3:04 wait a moment under glovebox is cover you can not take resistor under glovebox without disasembling glovebox?
Am un seat Leon 1p 2008. Unde găsesc sa schimb motorasul. Baga aer ușor cald în loc de fierbimte

1.8T AUQ I DONT HAVE RESISTOR... This is normal?
hi, i have a seat toledo. the fan was making funny noises, then stopped working,then started again, now its stopped again. doesn't work on any setting! would this be the fan motor or that little fuse thing you soldered on? great video by the way, i thought changing a fan motor meant stripping down whole dashboard! this will save me a few euro's!
hi. if the fan works only at the 4th speed, that means the thermal fuse is burned. if it does't even work on the 4th speed, you have another problem. the fan motor may be damaged, or there is a connection problem on the wires, connectors or even on the resistor block. you can remove the motor and try it with 2 wires connected from the battery. this way you will know if you have a fan motor problem or a connection problem.
My polo vivo is making funny stench of water coming through inside the passenger mat. The whole area is wet. When I try to drive it pours all the water from the bottle then start flashing temperature warning signs
Will do irlt in min have loud high sound on 1st level
Salut se poatE da radiatorul clima jos pe langa torpedou ?
salut. trebuie sa desfaci mai multe componente pentru a ajunge la acel radiator. aproape toata partea de jos a bordului. o sa incerc sa fac pe viitor un tutorial si cu asta :)

Where is the blower motor on a seat leon mk2
Am avut aceasta problema și la un Ford Focus din 2004
Trebuia schimbata numai acel "thermal fuse"
what kind of thermal fuse can I use to do the same??
hi. it depends on your car. for most cars of this generation it's a 250V 10A 192° C thermal fuse.
@@Sorin_DIY_Mechanical_Nerd It needs to be greater than 10A as the fan takes 22 Amps on the fast setting according to the fan data sheet so it needs to be 25 Amp or greater. ( This assumes that the fan is in circuit in the high speed position, I don't have the circuit diagram to check) If not it needs a current rating to cope with the current on speed 3 which is probably > 10A. You could check by putting an ampmeter in circuit in place of the circuit fuse but that will need the thermal fuse replaced to test it.
Salut .. Am avut si eu exact aceeasi problema la un SEAT CORDOBA 2003 .. Am fost la un "electrician" si a facut ceva de genul dar nush ce sa zic exact .. ideea e ca nu merge pe treapta 1 doar pe 2 - 3 -4 cred ca a pus un fir acolo inloc de rezistenta.. Ce rezistenta trebuie sa cumpar acolo si unde as gasi asa ceva ? Respect
Salut. Inseamna ca a montat acel fir in loc de siguranta, apoi a deconectat treapta 1. pe treapta 1 se incinge cel mai mult blocul de rezistente, scopul acelei sigurante termice este sa se arda, daca se incinge la un nivel periculos (ex: daca se blocheaza motorul aerotermei). indiferent daca ai "fir" sau siguranta termica, este indicat sa NU folosesti treapta 1. Deci faptul ca a dezactivat treapta 1 nu e o problema :) . siguranta termica este de 192 (grade C) 10 Amperi. costa aprox 5 lei la magazine de electronice (adelaida, quintrix). Este indicat sa montezi siguranta...
Salut sorine 2 intrebari am daca vrei sa ma ajuti si pe mn.
De unde pot sa iau o siguranta pentru un ibiza ? O gasesc la un magazin de piese auto sau mai degraba la unu de electronice?
Si atunci cand o lipesti are plus si minus sau nu contz ? Merci
salut. gasesti siguranta asta la magazine/site-uri de electronice, gen Adelaida, Quintrix... cred ca se poate conecta in ambele sensuri, dar eu zic sa o lipesti ca mine.
wather & electricity... not the best solutions:)) Be careful. God tutorial.
Klíma is működik így?
Salut . Dacă este clima și aseară am rămas fără dezaburire , se aude acel motoraș ,pe care tu l-ai luat jos ,ca nu mai învârte decat ffff slab ,bineînțeles că nu suflă decât fff slab ... Care ar putea să fie problema ? Mulțumesc anticipat.
salut. trebuie sa verifici mai intai daca e gripat motorasul aerotermei. poti sa incerci sa il cureti, sau sa il schimbi. daca e bun motorasul, inseamna ca e o problema pe partea electrica pana la motoras.
Where i can buy this small thing 🤔

Salut! La Seatul meu Leon 1 P 2008, ventilatorul nu mai merge deloc. In primavara, pe timp rece, s-a auzit ca scartia putin. Poate fi aceeasi cauza? Multumesc!
salut. probabil s-a blocat ventilatorul. poti sa incerci sa il cureti.
@@Sorin_DIY_Mechanical_Nerd Mersi! Mi se părea că e ceva asemănător navelor spațiale. Dar e mai simplu decât am crezut. Ventilatorul este sub bord și se demontează prin simpla rotire. Era într-adevăr gripat. Am rezolvat cu puțin wd 40. Din păcate, după ce inițial am dat jos torpedoul, deși nu era cazul ;)
De unde ai cumparat siguranta?
salut. de la magazine de electronice locale - Quintrix sau Adelaida.
Sorin I have Volkswagen
Passat blower fan not running on any speed
Seat Leon 1M / Toledo 2 / Golf IV /Octavia 1U / Bora / Audi A3 8L what else? Beetle? A4 Passat
Salut nu îmi funcționează prima treapta la aeroterma și problema e următoarea după un drum de 400km ac ul a funcționat perfect după ma trezesc ca nu mai funcționează prima treapta a aerotermei și becul de la ac era aprins când era butonul apăsat și când schimbam treptele de ventilație la 2 3 și 4 becul se oprea și nu bagă rece ,compresorul funcționează freon este in instalație și nu i dau de cap și nici la service
salut. partea de AC nu imi dau seama ce problema are. dar intai trebuie sa repari vitezele aerotermei. cred ca tot blocul de rezistente trebuie sa il verifici. probabil e arsa rezistenta pentru treapta 1, sau sunt oxidati pinii blocului de rezistente. sau motorul aerotermei e gripat si pe treapta 1 nu are destula putere sa se invarta.
Salut. Siguranța aceea se găsește în magazine de piese auto?
salut. o gasesti la magazine de electronice, Adelaida, Quintrix se mai gaseste si la magazine on-line.
@@Sorin_DIY_Mechanical_Nerd Mulțumesc mult
Salutare sorin ,unde pot gasii rezistenta aia?
salut. te referi la siguranta termica? se gaseste la magazine de electronice - Adelaida, Quintrix. vad ca se gaseste si la emag www.emag.ro/siguranta-termica-elsales-els-ter-19210-temperatura-de-operare-192-c-250v-10a-els-ter-19210-ax-47/pd/DHYX1KMBM/
Da ,multumesc frumos ,imi place ceea ce faci !!❤️
oare la octavia 1 e la fel ?
e acelasi tip de rezistenta, dar probabil difera putin cum e montata.
Ah, my Vladmobile is pleased
Salut! te rog frumos daca poti sa ajuti cu un sfat. Am o Skoda Octavia 1U2( este aceiasi lucru la Seat) si aeroterma merge cu turație redusa pe toate treptele selectorului si din cauza asta AC-ul nu mai funcționează..Daca este devina tranzistorul asta pe care l-ai schimbat tu de unde pot sa imi dau seama? si ce specificatii are? ca sa-l pot cumpăra.. Mulțumesc frumos! :)
salut. eu am schimbat siguranta termica de la blocul de rezistente al ventilatorului. daca e arsa siguranta termica, treptele 1, 2 si 3 nu functioneaza deloc. treapta 4 e conectata direct la comutator (fara rezistente sau siguranta termica) si alimenteaza ventilatorul cu tensiune maxima.
la tine e alta problema. daca se invarte greu ventilatorul pe toate treptele (inclusiv pe treapta 4), dar e totusi o diferenta de turatie intre trepte, e posibil sa fie ventilatorul de vina. trebuie sa il scoti si sa verifici daca se invarte greu. poate e de ajuns sa il cureti si sa il ungi.
daca se invarte cu aceeasi turatie pe toate treptele, inseamna ca are o problema de alimentare. trebuie sa ajungi la mufa sau firele comutatorului, sa verifici daca e vreun fir sau contact intrerupt. ai nevoie de un multimetru...
Multumesc frumos Sorin!!:)
Salutare..La Skoda Fabia 6y2 este la fel bordul??întreb deoarece pornesc ventilatorul, funcționează cam 30 de secunde și se oprește (pe toate treptele de viteza)..
Great video 👍 looks like a poorly designed assembly! A car you can not use a fan on setting 1??? Crazy..... add the rear light than taking on water like a small bath...these VAG cars should be sold as enthusiasts only ! As they need loads and loads of repairs!!!!

Why do auto makers still use such inefficient and ancient technology to control the fan speed?
That's so odd...
Greetings from Portugal.
hi. Seat Leon 1m (2000 - 2006) uses technology borrowed from Vw Golf 4 (1997 - 2003). Golf 4 was designed in 1995 - 1996. so this technology is more than 20 years old. at the time, it was a good design, that they could use in these cars. but after 20 years, the weak points come to the surface...
It's a cheap way of doing it - permanent magnet motors are a lot cheaper than ones with wound field coils. The fan motors used in a lot of Rootes Group & BMC cars in the 1950/60's had wound field coils and controlled the fan speed by varying the field current. Much lower currents resulted in less power dissipated in the resistor. Some even used a variable wire wound resistor to give continuously variable speed. The problem with permanent magnet motors is that the magnetic intensity of the permanent magnets decays with time. This results in the current demand (and the motor speed) increasing. Once the magnets have decayed to about 70% of the original strength the current will exceed the 40 Amp fuse rating on the high speed position and the supply fuse will blow. I have not done the speeds where the resistor is in series but suspect the current also increases resulting in the resistor overheating and the thermal fuse blowing. The situation is worse if you have a high resistance in the airflow duct as the airflow is used to cool the resistors.
@@johnmurrell3175 thank you. Precious information.
@@VitorMadeira I had to did my text books out from the 1970's to do the calculations ! I looks like some of the equations are still in my memory.
I thought the bearings on my old fan had failed as it stops quite quickly if you spin it by hand but the new one is much the same. The reason for the large amount of friction is probably the high copper content of the brushes and the high contact force to cope with the 22 Amp running current and to survive the 150 Amp inrush current if you start it with the switch on the high speed position. I would recommend turning the fan off before you turn the ignition key on - that way the inrush current will be limited as you advance the switch through the low speed positions to the full speed position (if required). If not the inrush could well damage or weld the relay that powers the auxiliary circuits.
One thing I should mention is that the fan uses about 260 W when running at full speed - if you have the aircon on this amount of heat has to be removed before it starts cooling the cabin. However in the winter the heat helps demist / defrost before the cooling water gets warm and the heater starts working. I am not sure what the power used is on the lower speed but the airflow has to cool the resistor which is why it is mounted in the air duct.
