No hot or cold air in your Zoe? Fixing the heater blower fan in a Renault Zoe.
Вставка
- Опубліковано 4 жов 2024
- In this video, I show you how you could fix a broken heater fan in a Renault Zoe. If your fan is not working, this is likely to be the fix and it can be done yourself with basic tools, saving hundreds of pounds. I've seen this job cost £500 at dealers. You could fix it yourself for about £100 and in about half an hour.
The fan controller (resistor pack) is part no. 271500017R and at time of making this video (Jan 2022) costs £85.11+VAT from a UK Renault dealer.

Sympathetic chuckling here when you cut to the car in bits... Even before you said it, I thought "oh dear, that didn't go well!" Not many chaps would have stopped to think about who they could help at that moment. You're a good bloke Matt, that must have been really frustrating but you made something useful for us out of it. We'll done and cheers. 👍 😊
This happened to my Zoe too. Replaced the resistor, but still not working. Took out the bottom right 10 Amp fuse that controls the fan and locked car for 10 min and the fans work again. Quite fiddly to replace the resistor. Using my iPhone in Video mode with flash on helped a lot to locate everything.
Wish this video had been out there two years ago! Great service you provide Matt, thank you for sharing these tips.
Great video! More Zoe stuff please!!
Brill video.
Did you read Haynes Manuals?
The classic Haynes line crept in...
"Refitting is the reversal of removal"..🤔🤣
Top job as always👍
Great video, thanks for sharing.
As always, many thanks Matt. Very helpful!
Your videos are great and you have saved me masses of time fault finding! I can’t thank you enough!
Glad to help.
So, clear and well put together video which I watched multiple times and checked my symptoms were identical to the description, but when I replaced the part it didn't fix the problem. So - probably worth doing but it's cost me some $$ (I'm in Australia) and time an am no further forward. I'll get an auto electrician involved now.
Thank you for the video - this fixed an issue I had with the blowers. I used a salvage part from a breakers, and the whole job cost about £30.
Glad it helped
Thanks for this video, this helped me get the blowers working again!
Glad it helped
Thank you very much Matt. I had exactly the same problem and fixed it the same way by replacing the resistor unit. Just don’t do what I did and mix the old and new ones up and have to do it all again! However it was worth it to find out that the old one was getting extremely hot after a very short time connected - the cooling fins were too hot to touch. If that is happening to yours after just a minute, a sure sign it needs replacing.
Yeah, it was the same on my Vauxhall Cavalier. The fan would stop working because the diode in the "resistor" module had blown. I was told that it was a common job at the Vauxhall dealers. I bought some diodes and replaced the diode. Cost was about £1. I did that job a few times over the 8 years I ran the Cavalier.
Yes I'd heard this is common on others older cars. But I was also told that the Zoe didn't have a resistor module...hence why I went looking for the fan.
Thanks Matt, useful, hopefully won't need to do this - but always good to know.
My other half’s Zoe had this problem stopped working one day booked it in to a garage but luckily it started working again the next day 😃but now if it happens again I know what to do thanks 👍🏻
Thanks for another helpful video.
Thanks for the video. Renault are poor and seem disinterested in our Zoe. Fan problem fixed.
Glad it helped
That's interesting! 💪🏼👍🏼
Great video, many thanks
brilliant thansk you
might be much harder to reach the module on the LHD version of Zoe ...
And they still use resistor packs on modern cars? I thought that is now today all controlled by electronics and pwm or similar ...
I'll try this out! I'll check out your vids for any other tips for why my heating might not be working in a 2014 Renault Zoe?
Heater problems in the Zoe is normally due to low refrigerant. The heat pump uses the air conditioning compressor and really you need to regass the cars about every 3 years. See www.gogreenautos.co.uk/how-tos/renault-zoe-heater-not-working
Very interesing video about Renault ZOE PTC heater. How install ? Where location ant etc.
Zoe has a heat pump, not a PTC heater.
@@GoGreenAutos Other ZOE versions have a aditional PTC heater, conected to PDM module.
@@miciusbmw Sorry Yes you're correct. I forgot the Zoe has a small PTC heater to assist the heat pump.
@@GoGreenAutos ThankYoo fo answer. Very interesing all information about PTC. On My Zoe 2014 year, no PTC heater, heat pump in -5C conditions always work at max heat mode without ECO mode, for me not enougt heat power. Heat pump serviced by Renault Dealer, freon quantity is normal. I using small 150W heater in 12V, but is very very small help. Legs heating is very weak.
Hi! Great videos! My issue is vibration starting from the 3rd speed of the fan. I am assuming that it is coming from the blower. You don’t have any videos on how to remove the blower right?
No only this video. It's very awkward to get in and out.
A somewhat related question: a spinning noise has randomly appeared when the heater fan is on. I can hear it quite clearly from outside where the air intake is below the windscreen. Is there any what to get to this to see if anything is stuck in there? It‘s not a problem (yet) but just annoying.
Often caused by a leaf in the system
Great video! However after I replaced the resistor pack with a brand new one, the fan still doesn't work. I measured the input voltage on the fan and it gets proper voltage which correctly vary when I adjust the fan speed up or down on the dash. Do you have any hint where to continue the troubleshooting?
Sounds like you need a new fan motor then.
UPDATE: I removed the blower unit. The fan actually wasn't faulty. During a bench test, I connected it to a spare 12V battery and it worked perfectly fine. I cleaned the commutator with contact cleaner and reconnected the unit to the car. First just hooked up to the input wire and started the car and voila the blower was working perfectly!
The removal had been complex, but the refitting was a mega-nightmare! I worked on a righthand drive Zoe. This car is the 'pinnacle' of French engineering. You can barely remove the blower but ultimately it comes out. When you try to refit, it doesn't go back, because the rim of the blower housing stuck into a massive steel plate which belongs to the steering column. I did not mess around with that part, because it looked to be responsible to adjust the distance of the steering wheel. Therefore I removed approximately 1-2mm material from the blower unit's plastic housing where it couldn't get through. Finally after a 2-3 hrs of struggling the blower was back in place and the car is nicely warm again.
TIP: Use a socket wrench with a flexible adaptor. Also try to use a socket wrench which doesn't come off, because most of the time you will work blindly and the last thing you want is to drop a wrench into the abyss of the interior parts.
@@gyulabakonyi8726 yes I found it a nightmare getting the fan back in. I managed it without any trimming, but it took a lot of attempts.
Hi Gyula, looks like I am similar to you - I replaced the resistor pack and it hasn't fixed the problem. Did you fix this in the end and any tips for a next step in diagnosis.
@@barrydarnell5879 hi Berry, I started with the resistor pack because that seemed easier to access and replace, also did not cost too much. After it didn't resolved the problem, I had to remove the entire blower unit. Removing is difficult but doable, but reinstalling is a nearly impossible due to the bulky design of the blower unit as well as a massive metal component of the steering mechanism which is exactly in the way. So, I simply cut off a bit of the plastic casing of the blower unit and it allowed me to rotate it back in place. Before reinstalling, I connected the blower to a 12V battery to test it. I hope it helps.
Did you find a way to test the resistor pack to confirm it is dead?
No. I don't know how they work. But I'm sure that info is probably somewhere on the net as the same component is used in most heaters.
Hi thanks for the video, how can we be sure the failure comes from the resistor pack? Any way to test it? Thanks in advance
I checked the 10A and 40A fuses mentioned and they were ok. Also tried disconnecting fuse and whole battery. Also discovered old resistor was very hot after just a few minutes with car switched on.
Great video Matt. Our 2015 Zoe (22kWh Q210) has recently developed quite a noisy compressor / heat pump which is very audible when driving and you can feel a bit of vibration through the steering from it. All the heating and cooling appear to be working fine at the moment but I wondered if you know if this is a symptom of something about to fail or a sign it needs some maintenance? I know the Zoes are loud when the heating/cooling is running at full whack but it doesn’t seem to ramp down to a quieter level anymore.
Get it regassed ASAP. It should be done every 3-4 years. You may find you need a new compressor at some point in the future, but a regass now may just catch it.
Ok thanks, it appears my AC is working again since a few days without issues...
The heater resistor pack on cars in general can fail because the lubricant on the heater motor bearings has dried out. Often the resistor pack has a safety component that fails due to this and fan then only works on max setting. Expensive job at dealers, can be done by owner, it's simple but awkward, you may have to use bad language on it!
Good to know, thanks.
Hello! Thanks for a very good video. Do you know how to change coolant on Renault Zoe? And do you know how to change the gearbox oil on a Renault Zoe
A gearbox oil change video will be coming on the channel soon. I've done similar videos on other EVs - see www.youtube.com/@GoGreenAutos/search?query=gearbox%20oil
All EVs are the same, but I will record a Zoe soon. As for coolant on the Zoe, not done that yet.
Does anyone know of a video to put back the denso a21201700 Renault zoe heater valve motor? I removed it to replace the thermistor, but I'm having difficulty re-attaching it to the white plastic and then back onto the mounting holes to be screwed in. I can see the way the motor screws in; but does the plastic arm at the back need to slot into a groove somewhere?
Hey! Do you know if the Can clip fault code reader works for the electric car Renault Zoe? I have a 2019 model year. Thank you! From Tommy Bertilsson from Sweden
I don't know as I don't know that product. But if its for Renaults, then I would expect it will. There must be a list of compatible vehicles on the manufacturer's website??
Why on earth would Renault use 5.5mm bolts? Why not 5 or 6?
French!!
VW using same bolts 5.5 or 7.5 i don't remember, , T5 for example. true headache))
Where are you based in the UK?
Oxfordshire
does this part control the heat to?
No, just the fan speed. If you have no heat, then its highly likely that it needs re-gassing. See www.gogreenautos.co.uk/how-tos/renault-zoe-heater-not-working
@@GoGreenAutos got the car re-gassed. Nice and cheap lol. Bit warmer bit still not great
Think il search out if there is a heating element somewhere
@@StephenLyons1984 It has a heat pump
@@GoGreenAutos my heater has just started working great. i did nothing changed nothing. but have nice hot car now. she is blowing out 48c air. was wondering if the cold spell we had helped or was there a pocket of air blocking the heat pump. but nice to have nice hot air
Very useful, thanks very much!
