Replacing a Hymer / Fiat Ducato Heater Resistor
HTML-код
- Опубликовано: 4 дек 2024
- 2008 Hymer B544 based on a Fiat Ducato chassis.
Heater and Air Con only work on max speed setting (4) all other speeds are dead 1,2 & 3.
Usual cause is a burned out resistor but they are hard to find if you don't know where to look.
If you do know where to look then it's a 5 minute job.
It took me lots of digging to find out how to do it so I hope this short video helps the next person.
Really all you need is a 5.5mm Hex socket (or small wrench/spanner) and the replacement part (About £10 , $12 on Ebay).
I reckon this could save you a bit of money, time and energy rather than taking it into a workshop.
Many thanks for taking the time to post this. I had this on a VW T5 so as soon as I only had one speed on my Ducato I knew what the problem was, but not where it was! Thank again
The reason for this resistor failing might be that the bearing on the fan is sticky. Then the fan will not speed up and the temp fuse on top of the resistor blows. Some correct oil on the bearing end a new fuse and the fault is history. (this video is one of the best instructions I've seen for ages!)
The bit that I needed was your instruction to slide our the resistor. Easy when you know how but impossible if you don't.
Really helpful, thank you so much - 10minute job now the blowers are working perfectly! Really appreciate you taking the time to make and share this video
I've benefited several times from other folks' RUclips videos.
One day every helpful hint & tip will be on it.
One of the best instructional videos I've seen. No nonsense or hogging the camera and pin points the exact location of the resistor. Helped me enormously... thank you so much, and happy camping.
Cheers, that was the aim.
Great video, saved me a lot of time and probably frustration! Took me 40 mins to replace the resistor and burnt wiring, fan working well now. Many thanks 👍😊
thanks for taking the time to post this well explained procedure, everything needed including 5.5mm socket size. Got mine off today following this and able to check part before getting one for £11 online. Used a mirror and torch myself, as van in a tight drive, to find parts without neck strain!
Thanks so much much, I was about to take apart the dash thinking the problem was the switch!! I was able to test it with tinfoil and it worked so I ordered the part and installing the real one tomorrow. You've given me back my van heating.
Just done mine after watching,
Made the job painless. Thank you so much👍
Thank you so much for taking the time to do this. The detail is tremendous.
Thank you for a great explanation. I knew what the fault was & what was causing it but didn't know where to find the rheostat/resistor. 👍
Thank you. You spared me from headaches from the noise and cold feet when I use the AC.
I was lucky: There was only a bad contact in the connector.
Done mine yesterday. Before I purchased anything, I took out the resistor, cleaned the plug and sprayed some contact cleaner on the pins. Working perfect now.
mine sprang back to life after an unsuccessfully dismount last summer, having got the connector free, but soon reverted to no4 only. Did not mind in extreme heat! Now with new part on order will always have a spare if connector was the issue
Another big thank you goes to you for sharing and helping! Appreciated! I see many people have already said thank you and I join them since I have the same problem that is addressed in your video! Happy holidays in 2023-2024!
Thank you . I never expected it to be so helpful when I did it. It makes it worthwhile now.
Hey Humberto,
Thanks a lot. Got other messages that it would be 1/2 day of work. Luckily I do have a passengers door. Very easy !
Nice one! This has just fixed my 2016 Peugeot Boxer. Resistor cost £11 on ebay and took 5 mins to fix. As others, my fan would only work on full speed, now it works as it should. Thank you.
Thanks for this vid.
In a LOT of cases the contacts just need cleaning. Certainly worked for mine.
Excellent thanks. Especially the need to slide the unit along prior to removal.
Thanks man - had the same issue on my Elddis and couldn't figure out how to remove the resistor, Saved me a lot of swearing!
Thanks really appreciate your help, could have taken hours without, even finding it’s a 5.5mm socket 😂👏👏
Thank you, together with your video it really is a 10 minute job !
Many thanks for such a detailed description. Very well done and very clear to understand.
thank you for this video, local garage quoted me £85 plus the price of a resistor. I am confident that I can now do it myself thank you
Thanks, Saved me hours trying to figure out where it was
TY, now I know where to find this resistor, mine has blown twice before.
Thanks for this video mate, finally got round to checking mine in my Peugeot Boxer, as it would only work at #4. Pulled it out and checked the resistor with a meter. Resistor is fine but the whole thing is corroded, so sprayed all the contacts (plug and resistor pack contacts) with electrical contact spray, and plugged it all back in, and it's working again. I've also got a new one on order :) and will swap it out as soon as it arrives... happy days.
I’ve just replaced mine, the old one looks like straight out of the Titanic! ⛴️
Thnx for this video, just replaced mine on our holliday in about 5 minutes!! 👍🏻👍🏻
Thanks, especially the tip about sliding the resistor out. Checked resistor pack with a multimeter OK. Mine turned out to be bad contact in the connector. Bit of emery paper and all working again.
Thanks for the video. Very usful indeed. Saves a lot of time and effort. Now need to see if I can find a spare in Spain.
Thank you for posting this video. You just saved my day. 🙏
Great footage, thank you; was on the verge of taking my Motorhome to the garage... just need to get the component ordered and will give it a whirl....
El único video de verdad que explica el truco para sacar la resistencia. Gracias
Very good intruction, thank you so much. Keep up these helpful tips ! Greetzzz
Thank you very much.
Nice and comprehensive explanation
great vid and very useful. thank you. Only point i would add is that in my experience, having a left hand (passenger) door doesnt help. still easier squeezing in like you did
Thanks for your video, great help, greetings from Hannover, Germany
Really helpful - Thanks. Worked on our Autosleepers. Would have spent ages trying to pull out the old resistor without this - or given up and gone to the garage.
Great video many thanks for taking the time. Now I can have a go at mine and as it's a coachbuilt I can go in via the passenger door. Happy Days
Thanks. Took me 5 minutes after stripping out glovebox thanks too your video.
Thanks for this. Just had my 2009 Bessie blower on a Fiat Ducato fail apart from when on full so a new resistor required.
Thank you so much! I tried for an hour to get it out. Thanks to you I know I have to push it aside. at last :-)
Thank you so much for posting this information. I replaced resistor & hey presto fan now working perfectly on all speeds 👍👍👍👍
Great video. Saved me a lot of head scratching. Thanks!
Brilliant bit of video. Just what I needed. Cheers.
Thanks! we will try this best regards Peter and Yvonne
This is a very good video, thank you for posting.
Thanks, this video was big help for me to solve the same problem.
Many thanks for this - had intermittent problem as you describe which turned out to be loose connector which is in exactly the same position on my 2010 Citroen Relay.
Brilliant, very helpful! Also works for the Qubo as well!
i have a non working fan motor - been like it for a year, but as i have an auxilliary diesel heater, i wasn't too bothered with it. But now we heading in to colder weather, i feel it incumbent to get the thing working - not so much for the heating in cab area, but to dlear inside of windscreen when it mists up. i ordered my resistor from Germany - it was a lot cheaper than ebay, and didn't take very long to arrive. Going to try and locate the old one today, and like your video, i also will video it if possible for future reference for other people with same vehicle as myself ( Iveco 50C13 16 seat minibus) Many thanks for your helpful video on this subject.
The problem I described is that the fan is either (1) Off on settings 1,2 &3 (2) Only works on setting 4, full speed.
The fan DID work but only on full speed.
The resistor is used to slow the fan down.
If your fan DOES NOT work then you have a different problem.
Very good video. Thanks
many thanks you you saved me a lot of time. great video
Thank you, I was cussing because I bought the part 1st and couldn’t get it off (simply slide it…. Trying to break it off before watching this), that is after the 5.5 socket that I was cussing about but had one in a kit so job done. Thanks again
Cheers, very helpful! We have a gentle fan again. 👍🏼
Thanks for this instruction. Hopefully similar to my 35S13 Daily camper. Fan stopped completely fuse and relay appear Ok so next up is the resistor - Hate working in the footwell!
Did this without any problems thanks to this video, thanks for putting this up! ow I just need some physio for my neck....
Thanks, this helpful video worked for me and the blower is now working on all speeds. :D
Brilliant thank you, got the same to do on mine, will save a hours of guesswork
Very helpfull! Thanks a lot! This saved me some time searching for the resistor!
Thanks a lot for your video, saved me a lot of time! Thx again!!!
No problem. I've used other people's videos to figure out a whole host of things. Glad I could be of help.
Great use of the camera in a tight space.
Great video thank you ❤️
Thank for that. I'm glad I've got a passenger door.
Thanks very much, saved me a few quid.....well explained..could do with smaller hands😂
Great work! Having exactly this issue with our heater fan, so hopefully a replacement of this assembly will help us as well! :-)
Thanks alot for the tips. Maked some more savings by just changing the resistor heat fuse. Simply clip it out and welded new one carefully 1€ a piece from local electricalstrore . Easy piecy.
saved me a load work ,cheers
Very good explanation, thanks.
That was awesome. Thank you so much.
Thanks for a great video. Still to tackle mine 👍
Many thanks saved me hours 👍
No problem. I'm paying back RUclips for all the techy info I've got from it.
Thank you my friend. Realy helpfull. İ solved the same problem. Ducato 2009.
That’s for a brilliant tutorial 👍🏻😎🌞
Thank you so much for this!
Thankyou very much
The cable have burn and it has 4 cables and no I need to know witch cabel is on No1 to No5, there is 5 connection but only 4 cables, the colours are black / black-white / black-gray / gray
The black and black-white is thicker.
Need help and thanks for a great video
Thanks alot!
Very helpfull, thank you for video.
My fan isn't working at all, checked all fuses. Will be the same problem?
Good video bud, helped me out !
Thank you soooo much 😊
Thanks buddy helped me out just come across exact same problem...
Glad it helped someone.
I had this issue, I went to check mine today and one of the wires has melted, I unplugged it and plugged it back in and now its working again, probably not for long but it'll do for now
Think you've saved me a lot of agro... Part orderd..
great video. Thanks
Mine problem is a bit different. Whatever speed I select it is all blowing at maximum. Even when I select 0, it does not want to stop. It was too hot and entire day driving with a/c and fan at max.
Do you think is the resistor or the selector melted ?
Try a new Resistor first, as it's cheap and easy to try.
thanks for answering dude
that is a brilliant no nonsense video
no miles of waffle , i love it sure will save us lots searching and struggling to do ours if need be,
do you have the new part number please? thank you & happy camping.
I think the best thing to do is extract the faulty one and get the part number from that. There are several different types out there and I think I got lucky just eye-balling it on a web site.
Thank you, it helped.
Thank you!!
I don't know you, but, if I did you would be getting a Large (make that a dozen) bottle's of the wine you prefer. Changed this last year in the South Of France $95 Euros. It took the frog mechanic IN A FIAT Dealership 45 minutes to change it. Just been turned back from entering Scotland 19/04/21 by the Police and it blew again. Back in Leeds, watched your video , bought the part £39 and fixed in 10 minutes. Yeeeha, for folk like thee cithie.
Apparently we are only allowed to enter Scotland from the 26th of this month?! I could not make this up!
Amazing help. Any idea what the ohms reading should be if tested?
Cheers
Yes.
A very informative video you made it look so easy, would the location of resistor be similar on a B644 2001 LHD Fiat Ducato Chassis, at the moment fan not working.
I'm guessing yes....but there's only one way to find out. However if it's not working at all then I think you have a different issue. Worth pulling out the plug and resistor to check though.
@@gohumberto Hi thanks for your reply, i will first locate the resistor & then get an auto electrician to find what the problem is as i would not know where to look. Will let you know of the outcome
Thank you so much my man
2004 B614 has a phillips screw not a 5.5mm bolt that holds the resister in place.
Well done and thanks you🙂.
Hi
Thanks for the video, I have just replaced mine however the heater is still not working. The AC light works now when turned on and off, this wasn’t happening before. Still no air or heat moving whatsoever on any setting. Any ideas ?
Maybe the fan is seized?
@@tonyr1963 the motor was burnt out. It had short circuited and the motor fried. All sorted now. Cost a fortune
Thanks for that, where is the best place to get the resistor?
I got mine from 'SVX-Online' via Ebay UK. I have no financial connection with them, they just came up when I searched on Fiat Resistor.
thanks!!
Hi, nice video. My ducato 2008 fan has stopped blowing this week, all 1-4 stopped. Resistor? Or fan? At least I know where to look now :-)
The resistor problem still allows the fan to work at full speed.
Yours is a different problem.
It's likely to be the actual switch (the piece behind your 1,2,3,4 position dial) that is burnt out. see at 3.00 mins at this link: ruclips.net/video/HwQECDGve4g/видео.html "Go Humberto" - I hope you don't mind me adding the link to your post. Your video has been excellent and helped me with my Citroen Relay Van , where like yours, the strongest position (position 4 on my switch) worked but 1,2 and 3 didn't because the resistor was faulty and could therefored not function to slow the fan down. Big thank you to you for your great video and contortions to explain everything in great detail :-)
nice one. I have a Citroen Relay Van 57 plate, just removed/replaced the matrix on it, ( Leaking badly, BIG job, hopefully a vid to follow on that,) but also had the same issue over and above, hoped it was just the actual switch as in 90%? of cases, so swapped that first.. (Damn.. ) anyway already received new new resistor so will get that sorted ASAP guys.. P.s, if anyone needs info on matrix removal give me a message.. you'll need 12 hours if decent DIY'er
TIP: Always check first this connector on this resistor when you have problems with not-working fanspeeds or airco failures. I had to find out the hard way doing a lot of work checking al parts piece by piece.
Thanks!
