Hi,
on my S3 the fan and horn fuse is not in the dashbord.
It is a single 50A fuse in the engine wire harness, right side of the engine above the battery.
Did you check this fuse?
Sven
Sven,
yes i did, this fuse was burnt. I replaced it but it still does not work. I do not not if this is due to the overcharging which may have cause the fuse and relay failure.
i'll test the relay tonight.
Thanks
regards
Jérôme

Hello Jerome,
because the fans and horn are connected with the same fuse I would firstly disconnect one cirquit.
For example the fans (just remove the + cable from the relay)
If the horns work and the fuse doesn't burn then it must be a problem with the fan wiring.
If you don't want to waste the glass fuse then mmake a "flying" cable with fuse (cheap modern fuses) and connect it to the battery and the relay .
You can also just measure if the wire harness has a shortcut.
I don't think that fuses burn due to high charging voltage. I assume that there is a shortcut to - somewhere.
If the harness is OK then there could be a problem with one fan (disconnect one after the other)
Best regards
sven

Thanks Sven,
something that i should have mentienned which can also be the cause of these poetenail relay failures is that because of the transmission issue that i'm facing, i have removed the kickdown wire from the switch without having isolated it properly. This might have touched the body and created a shortcut. As the kickown swith, Horn and fans are all connected to the plot this might explain the issue. (explain also the fact the dedixcated horn fuse was burnt).
Do you think this might have burnt the fan and horn relay?
Thanks
Regards
Jérôme

Hi,
If you have now isolated the kickdown switch cable properly (or reconnected it)
there should be no problem.
I think a fuse should burn before a relay.
Perhaps I was inaccurate before. The switching voltage for the relays and the kickdown has a fuse in the dashboard. The current for fans and horns is secured via the 50A flying fuse in the harness.
You should disconnect the single cirquits and reconnect them one after the other.
then you will find which part or cable causes the shortcut. If you plan to replace the relays anyway then you could open them and have a look.
I would firstly check the relays with a 12V source and a multimeter.
It should be possible to find the root cause. You just have to check the seperate functions one by one.
Do you have the wiring diagram?

ven,
i have the wiring diagram indeed. I'll do all the test and report.

Hi everybody,
the fan and horn issue is now sorted. In fact it was indeed a fuse issue. The "flying" 50 amps fuse located on the RHS in the engine bay was burnt. When i had the issue i changed it but the brand new one was deficient and i could not see it. I discovered it thanks to the voltmeter.
I'll keep you posted on the other issues left: upshift and voltage regulation.
Thanks everybody for your help and support.
Regards
Jérôme

That's good news Jerōme but remember that fuses blow for a reason so don't be surprised if it happens again.

Yes you are right but i found the root cause. In fact when i have disconnected the kickdown wire i did not isolated it and i guess it touched the earth and blow the fuse.

Dear all,
to keep you uptodate, my gearbox is now shifting.!!! yes...
I have disassembled the vaccum valve which was actully stucked. now it works as it should even if i could not go far because i'm still missing my number plates.
I just need to fix the overcharging issue but should be ok with a brand new regulator.
Thanks you all for yoru help.
Cheers
Jérôme
