Hello again.
I’ve came up with the solution for error B1919 DEFROST SENSOR (stilo and bravo, delta and others) + other weird errors starting with B**** , but not for the climatronic motors .
Thanks again for help ,
@sibonios and
@aschiuta , and also to the fiatforum.com.
So this is what i did after going to the fiat service Autoitalia .
- the conclusion of the Autoitalia service was that the problem with Fiat Bravo s climatronic is that the cables are corrupt and the climatronic motors are stuck and old .
- we made an appointment after 3 weeks(from the date the diagnosis was performed), for this fix made by Autoitalia.
So I had 3 weeks to try to fix it myself instead of borrowing 1000 Euros for fiat service.
What did I do :
- After discussing with some fiat members and owners, I decided to change the climatronic panel. So far so good , I ve bought one used from 2012(I was lucky) with almost 100 euros ( by the way, a new climatronic panel is almost 1500 euro), and yes it worked
- It s hard to change the panel, I ve used for disassemble this video :
(Sostituzione Plancia Clima Automatico Bizona su Fiat Bravo serie 2) and I send all the best and thank you mr. JackTv G.T. )
This guy is a pro , and also he changed them frequently, if you never done it and the panel is virgin, be careful because it has 2 rivets or nits ( like the original speakers ), very hard to take them out, you ll need some tools, and patience , much patience also is needed when you put it back, that’s the hard part. I didn t film myself because I did on a hot summer day and yeah it was hard. If you got any questions I ll answer here or in the Romanian fiat forum, with pleasure.
So after the exchange , the odo-km was flickering (it needs the Proxy alignment) , but this was a success, climatronic worked for almost 3 weeks perfectly, I ve checked for errors and the B1919 was gone, but it had one error , B1922 Electric fan feedback present OC or SC to ground or rotor blocked ( the electric fan was new, replaced 1 week ago , found him hard, read the post and you ll find the model, its made by DENSO) , the error remained present.
We were happy that it worked for almost 3 weeks with temperaturs above 40 degrees Celsius!!!!! It was like he was reborn but…..
With 3 days before the fiat service schedule , the climatronic didn’t work, symptoms : strong sounds from compresor coming and no air from vents, no cold air and a loud noise, this was only when the ON button was pressed( snow flake button, climatronic on),if it was off the Denso fan had normal noise . So I thought that the climatronic motors had problems and they were blocked, didn t put the tester on … it was such a big disappointment
So he didn’t escape, we didn’t escape from debts…..and yeah after all motors got replaced in Fiat Service ( yes you can test them with a 9v battery, but the test is for nothing because they can work for one time and next time they won’t, so be carefull, replace them all to be sure with new ones….) the climatronic worked for 1 week, and again problems.
So after that I decided to disassemble the original climatronic panel and yes, I found the problems.
The fiat service was ok, but they didn’t resolve the problem, I mean the problems with the climatronic , because after service , after 7 days it didn t work.
So I’ll go to conclusions :
Error B1919, B1922 and other errors that don t involve the climatronic motors can be fixed, if you just clean the climatronic panel (its the same for STILO , BRAVO, DELTA and others )
Cleaning the climatronic panel : (THIS THING SHOULD BE DONE WITH THE ENGINE OFF AND NO KEY IN IGNITION )
1st step : you disassemble
(Sostituzione Plancia Clima Automatico Bizona su Fiat Bravo serie 2) and I send all the best and thank you mr. JackTv G.T. )
2nd step : you disassemble the climatronic panel , the exterior part has clips, easy with them and the mainboard is fixed by 4 screws and clips, easy to disassemble, easy with clips, proceed with patience, not to break them
3rd step : with a soft brush clean the dust inside, and also clean the SENSOR in the middle of the mainboard and also the grid from the front panel(it has dust and others on it) and yeah, the fan, the black fan , also take it out with patience out of the pins, clean it and oil it , and clean the excessive oil from the fan…and yeah you can clean the exterior buttons(the one which you press to control the air flow), I ve used “light machine oil”
This sensor and this fan are the problems…..i found this fan for new ( I didn’t buy it, we have no money left ) as climate control fan for : 1Pcs New Climate Control Unit Fan For AUDI A3 A4 Q5 TT 8P0959101 (you ll find it on ebay), but I will post some pictures with the original one from fiat Bravo, we have a code :9341706004 Papst
4th step : put all things together and test the panel, test it for errors
5th step : Good luck it worked, you deserve a beer !!!
P.S. If cleaning does not work, get a new or used climatronic panel, if you buy it used, IT NEEDS CLEANING and oiling.
So, I ve cleaned also the SH climatronic control and yeah, they both work, but don’t know for sure for how much time , you ll never know when something goes bad with Fiat climatronic, or others….
If you find out that this post helped you , like many posts helped me from this forum, feel free to support this forum and yeah, maybe you can do a nice good gesture/thing for someone in need ( cats , dogs, humans) and try to do good things in life, help others .
For any question feel free to put them here, I will try to answer them.
And yeah, Fiat bravo doesn’t have a defrost sensor, it says in the newer climatronic panel I bought (using the obd test), from 2012, this panel has also another software, but the same faults as the original from 2007, so clean them with patience and attention, and they will work.
Also after I've cleaned them up , I've searched the internet and yeah, other models of cars have this 9341706004 Papst, not only GM-Fiat Group
