Fiat Grande Punto heater not working --Fix 

This morning I decided to have a go at this after seeing your video last night. I had to work outside as my garage is not wide enough to make access possible. Got a kneeling mat in place and a small pound shop lamp to light the way! It was not easy to disconnect the plug when lying on my back across the door sill. Anyway I managed that bit and then it started to rain and I lost the lamp behind the centre console! Crap! Eased the side plastic and out fell the lamp and a woman's large ornate plastic hair pin! Gave the plug pins a quick rub and reconnected it. Bingo! It now works properly and I know what to do if it fails again. Not bad for a young old boy of 83 years! Many thanks for the good video and excellent talk through without any BS. I am very grateful at saving a garage repair bill at this time of year! Cheers mate! All the best to you!

5 year old video just fixed an issue even the mechanics couldnt find. My connections werent rusted but the whole thing was loose and out of place. Couple of minutes of pushing and pulling and making sure it was all right and problem solved! Thank you!

Thanks so much, during the winter, the car heater stopped working. I googled as I could not understand why this happened. But it turns out, this is a common fiat punto issue. I then watched your video. However, I didn't want to fiddle around trying to chisele the burnt off so went on Ebay (UK) and ordered one, you can pick up a heat resistor for £6-10. Anyway, before I fitted it in, another day, I took out the cable so it will be loosened. I did the fix on the pavement, it was a bit fiddly as the heat resistor was way back. I layed some cardboard, used amazon packaging on the ground for my knees, then took the cable out. I went tight in the car, used my fingers to push the tab, eventually the heat resistor came out. I took pictures, pin 5 and 6 was burned out. Before I even put the heat resistor back in, I plugged the cable back in and turned on the car. Yess, the heater was working. Then I took the cable out, pushed the heat resistor in, pushing the tab down and it slotted it. Note, the Resistor does not connect to anything in the white plastic casing. The White plastic casing on holds the resistor in place. Then plug the cable back in, job done. Took less than 20 minutes, did it on side of my house parked up. My biggest regret was putting this off, I ordered this weeks ago when it first broke in December and only fitted it in. Now, from the research I did, during the winter, best to keep the heater on around no.3, putting it on maxiumum heat and no.4 will likely burn the heater out. If it does happen again, well it is a easy fix and will cost around £6 to do, with no garage fees required. Thank you so much for your video, very helpful, as a female diyer, I was able to fix this so this is a simple fix.

I implemented the 1 to 1 as in the video and it worked directly. Don't buy a new blower motor or resistor directly. Try it this way first. It worked for my Fiat Punto Grande aswell. Greetings from Germany.

Superb. Followed this video and my heater’s have gone from completely unresponsive to fully functioning! Took about 10-15 mins as well! I had to use a nail file (I know) instead of a needle file as was he only thing that would fit, still working like a charm. Much appreciated sir, thank you!!

Thank you for an excellent no-nonsense, no-crappy music, straightforward video. :) It spared me a lot of time and fumbling around.

Thank you so much! It worked like a charm. For the people with a Punto Evo, you first have to remove some interior plastics near the transmission tunnel. The resistor is located behind some sound deadening up and under the glovebox.

great video!, straight to the point and resolved my issue within minutes, saved me a 20mile trip to my garage and im guessing a load of money!

Thank you thank you Back Street Mechanic - great fix. Had the same issue on my fiat punto evo....initially sent to garage to fix 3 months ago, which they did and charged me royally. It went again today whilst out on a drive with my son who is using the car for his test tomorrow. Followed your instructions and works like a dream. HOW EASY!!! Wont be putting it on setting 4 thats for sure. Thanks again

Fixed my daughter's heater just by watching this video. I looked a right treat upside down in the passenger footwell with my feet sticking up in the air whilst cleaning the connection. :)

I unplugged and plugged back the connector under the glove box and it's started working!! Now I will clean it like in the video. Many thanks!!! 😁

I used this trick after watching your video last year! It worked until this winter and Iv had to bite the bullet and buy a new one with a harness. EBay for a tenner now!!

Thanks backstreetmechanic. The fan in my Punto 2012 the fan only worked on 4. After getting the resistor out, checking it, cleaning the contacts with a small file and putting everything back again it works again. Cheers!

Thank you for the help, been without my heater for a few months now with little cash, one look here and I fixed it myself 😬

Thank you very much for this video. You saved me a lot of money, stress, and time. I just did this repair to my daughter in law's 2012 Punto. Once again, thank you from Middelburg, South Africa.

brilliant, that worked. especially the part on how to disconnect the thing (push the levers and slide the whole thing to the left) was very helpful. Thanks!

I did it. I had the same problem on my fiat grande punto. Now i fixed it. Thank you

Will try this shortly before buying the resister! Thank you for your help!

Smashing video! Didn’t take long at all apart from being head down attempting to put the resistor back in!! Thank you for this

As my dad says, you de man!!! Fixed my problem thanks to you!.. only managed to get full blast working but that is enough for now, looks like the connector block is properly buggered on mine..

Thank you my man! Solved the problem for me, winter is coming and I couldn't see out since the ventilation died and couldn't defog the windshield. It worked : )

Top man had the same problem with the transit connect, just ordered a new resistor 👍

Thank you for this video.garage wanted £245.i watched this tested resistor ok.motor had gone.brought new motor£45 denso brand new.10 mins it was done working fine.thank you again.

Great video. A quick wiggle and it started working again for me. Thanks

Thank you!! My air conditioner didin't blow unless it was on full (4)! now it works perfectly

Thank for this. Fixed my lad's Grande doing this.

Thank you mate YOU ARE A LEGEND

This video has helped me fix my Grande heater problem. Thanks a lot. :)

I had the same problem. Unfortunately mine was absolutely melted so I’ll have to order a new one. The video was very helpful though. Thanks

Great video, will try this weekend, looking at the video comments defo gonna save me some money 💰

This works! Thanks so much for sharing your knowledge - I had almost started on dismantling the dashboard to get to the blower motor

Excellent video m8 very straight forward compared to other content on RU-vid keep the videos coming m8

Thanks for posting this video. It looks like the components are common in a lot of FIATS and I think also IVECO vans. Looks like the draw of the resistor and fan is too high for the connectors and in some the fan fuse heats up and melts.

Thanks 😀 Where would we be without RU-vid ? Lol

Very informative and very easy to follow instructions...well played

Just fixed mine... this was very helpful, thank you!

Thank you so much ! I was so upset that my heater wasn't working, cheers mate !

Mines just gone today, will try fox it tomorrow. Thanks alot

Perfect, you just solved my problem! Thank you!

Thank you so much sir ! Cheers from France !

Thanks for the video mine was the same issue not working on speed 4 it is now fixed top man

Thank you for your diy video👌

Thank you so much that’s very accurate it actually worked the minutes i touched it .. seems like a common problem in them cars as you said

Thanks for a great video - worked a treat 😊

This helped me out today, thanks very much for making this video

Buddy thank you I’ve just had the same issue on my sons car but the harness block is so brittle if it goes again I may have to cut the wires and put my own spade connectors on each wire to go on to the resistor all sorted now

Epic!!..this worked a treat for me. Top bloke.

Thank you very much

Thanks a lot. It worked and saved me a lot of money

Thank you! This worked

loving your vids thanks for loading

I have 2 grande puntos great cars but both with this problem. Thanks.

Thanks pal. I hate it that my Grand Punto has so many common faults 😟 never gunna buy an Italian car again!

If you only have 4 speeds, then the 10 amp fuse on the rheostat itself has blown. This fuse it does not burn out due to a short circuit, but only due to heat, you can replace it with a synod that is placed on water boilers. From 10 amperes. But that didn't solve everything, because the cause of synod burning is dust in the fan itself, as well as its bearings, which need to be cleaned and lubricated.

Worked perfectly thank you 🙏

Great upload nice easy to follow sorted mine out

Thank you

Thankyou so much it worked for me. Do you have any idea why my lights are staying on?

Thank you so mouch for your time to share your knoledge, i would like to see how to repair or test button and lock mechanism on fiat grande punto 1.3 multijet 2012 on boot/trunk door, also want to know where is relay for central locking located in car? Thank yo a lot, thi video would be very helpful

Thank you very much. I fixed my Fiat Grande Punto’s AC ! Can you tell me how I would fix the light cos it's not turning off only the beam light goes off and on

Top man worked

Great video ,thanks......Fiat have known about this problem for years, Punto's, Stilo's and Qubo' all having the same fault and still fitting the same problematic parts. i dont buy Fiat any more. For most this is a temporary fix, it will happen again, or catch fire.

Thanks mate, and g,d bless.

Thanks for your help, problem sorted 🙂

Thanks, had the same problem, now it works perfectly!

Ok for me also, tanks for this video. Pierre, Belgium

Thanks for the tip Works perfectly

Brilliant this fixed it.

Absolute life saver!!!

Thanks !

Very Very Usefull !! thanks a lot!!!

THANK YOU SO MUCH!!!

very good

Hello and thank you for the video How did you extract the resistance?

Great help. Thanks!

great tip cheers

after cleaning up the resistor and female side block connector it worked fine... important thing to ask here..I noticed the resistor gets very hot....so I fitted a new resistor..and same..get very hot.. is this normal?

I have this with my Fiat Punto thank you so much for sharing this video also is it easy to disconnect the Loom and completely change it ?

Nice work mate

Clear and to the point

Thank you great work

I’m going to try this tomorrow, however is there any way that this could be connected to my windshield not getting the steam off?? Heater works but I just don’t know what to do at this point

Cheers mate

Nice mine had the same problem at speed 4 is now fix thanks

Nice on Sir, Thank you .....Bloody steamy windows...Lol

Hello. I tried this, but both my block connector AND my resistor were completely burnt out and melted. So I ordered both new parts on ebay. Trouble is, this means rewiring. But the wires that come from the existing ones in the car are different colours. (Old ones= brown, brown, blue/red, green/black and yellow/green) My new ones are black, blue, red, green and yellow. Can anyone tell me which ones go together please?

Muszę przyznać dobry manual. Szkoda tylko, że czasami elementy mało podświetlone.

Thanks for help 😁👌👍

Thanks mate big help keep it up
