Fan blower motor resistor - test 

Great to see someone doing a repair properly not just replacing parts , a proper technician .well done k-nemo

Thank you very much. Your info was spot on. Wish I had seen this before I spent $52.00 on a new one. I didn't even think to check the resistor before I bought a new one. Major brain fart. I had no power through all speeds on the motor. I troubleshot the circuit starting from fuses to motor. Had power to the motor so that meant fuses and relay were good. Hooked up a 12v motorcycle battery to the motor and that worked. Now either bad resistor or blower switch. This is when my brain farted. I knew that even if the resistor was bad I should at least be getting power on the highest speed setting and wasn't. But a small possibility it could still be the resistor so I gambled on replacement only because it was easier to replace than the switch. Oh well. We live, we fart, we learn. I snapped after watching your video and checked the old resistor. Sure enough, there was nothing wrong with it.

Very helpful info! Replaced mine on my Sprinter. When it didn't fix fan issue, I replaced blower motor and wondered if I'd replaced a perfectly good resistor block. Thought about selling the old one but didn't want to if it was n.g. After watching your video I know the top resistor (?) fuse (?) diode (?) is blown. Into the trash it goes!

I like this video. Normally a common go to component on a VW audi group vehicle if you are only getting fan speed 4. Common on the Polo’s but worth checking the blower motor too guys, in case that is faulty and causing series resistor to fail. Good work!

How Can you use the tester in “off” position ?

great little video

good video, but it could be great if you spoke, and had the Temptations as background music👌😎

Dziękuję za dobry materiał.

This fantastic video,has helped me so much again sir ,,,a most gracious thankyou,,

that was really helpful, stupid music in the back ground, instead of you explaining what you was doing, Thank You!

Well if 1 and 4 not connect a first resistor was broken. Its possible to make new from wire (i'm not sure is it cooper wire wrapped in case or different it corroded like steel) but wrapped must be correct with diagram. 3 resistors for first gear, 2 for second and one for thirtd gear

Super, très bien expliqué, merci à toi👍🏻🙋🏻‍♂️

Dear sir,an absolutely brilliant video. Superb thanku

Saludos Cambiando está recistencia resolvería el problema de que el blower siempre este al máximo y no baje su velocidad ?

Salut. Am o Fabia 2 și am o problema cu climatronicul. Cred că este acest senzor, mă poți ajuta un pic ? Mulțumesc

mine is blowing at max on all 5 positions 0, 1, 2, 3, 4. I can not stop it. Isnit resiator or relais or selector (knob) ? What you think guys ?

Meister! Thank you

Although, for me the one showing 0.0 was bad. And one with 1 . was good. Doesn't 0 resistance means closed circuit, fan constantly running? So shouldn't there always be an open circuit until it's necessary?

Thank you sooooo much, it help me a lot and i have fix it 🙂 i would like to see more video tutorial like this one, keep going :)

very nice and detailled video, love it

MAN at 1:14 you checking this correct thats why whole 3 gears not work. 4 pin and 3 its first gear (3 series resistors one not working and no ohm for all 3). Next 4 and 2 pin its second gear (2 series resistors one last is broken not ohm). 4 and 1 pin its 3rd gear (one resistor and its broken because its used on all gears)

I have the problem where my AC only blows on 4, but not cold. Problem was intermittent. I'm okay with the only fan on high as long as it blows cold. I have 4 wires coming in brown, blue, black and yellow. Any way to bypass this part with some generic resistor that will last longer and have it on high and cold?

Este normal ca siguranță asta sa arda destul de tare..chiar și la pornirea butonului din tabloul de comanda ???

I don't understand what your doing I have a similar one but what part of what you did showed where it was broken. I may need a new one, but don't know which bit of yours didn't work

Nice video. Do you have any idea on wattage of resistor? How many amps go through it

Wypadało by włączyć miernik a nie na off.😊

is it for four speed or five speed?

What repair happened? Am I missing something?

Music destroyed this video..

what is the rating of fuse , i know there must be max temperature and max amps

Why crazy music just speak.

I’ve replaced mine on a berlingo van 2009 and now the speeds are reversed any ideas why?

does that 1 mean infinity?

Hello il calling konfem cameroonian strident in automobile réfrigération and air conditioning here in douala i would like you To gave me the electrical diagramme of the 12v part of the automobile air conditioning There terminal pressure switch thermostat evorator fan condenser fan ac bouton four terminal relais and fuse

În citeva momente deja arde .!!!

That's like the cheapest multimeter.

how is the music supposed to help anything at all you need someone explaining what's going on

😆

.

not

k-nemo / MERCI Thank you 👌

Excelente demostración fácil y al punto

musique débile !

Thank you very much,help mi😉

FOR VAUXHALL ASTRA H MK5 1.9 CDTI 150 DIESEL 2004-11 HEATER BLOWER FAN RESISTOR can you show me how to test it off the car, & show why it doesn’t work..

Fără motorul pornit doar contact și ventilația fără AC .??

Esto puede provocar que se caliente el fusible al grado de derretirse al prender el aire acondicionado?

What is the resistor value ? 4k 60v?
