Hi, I've just come back from a camp trip. I used the 12v socket for an high pressure electric pump rated at 10 amps. Ive used the pump on my audi and not had any issues with the pump.
Basically it appears the fuses have blown instantly on both the front and rear 12v socket when Ive turned the pump on.

I've located what appears to be the world's most awkward location in the glove box but the manual has zero comparison to the actual layout of fuses. When I pulled out what was supposed to be the 12v fuse was in fact the systems auto cruise.

So does anyone know the actual fuse location and what amp it is? Pics would be great or a diagram. I can't find anything on the net.

Fuse 16- 15A is in the top row of fuses in the bottom RH corner of the fuse box (second blue one from the left):-

Hope this helps.

James, did this help you? I've got the same problem of the 12v sockets having blown fuses, but for the life of me I can't make sense of the diagrams as they don't resemble what I see. Access to the glove box fuses looks almost impossible due to the amount of cabling positioned in front. The fuses I can get a glimpse of don't match anything I can see I the handbook.
Any help would be appreciated.

I too cannot see how a fuse can be changed by the average owner.
My manual also shows a layout that does not match the box hidden behind a nest of wires.I am waiting to hear from CITROEN on this matter, But do members think they should take responsability and put
the fuse box where it can be accesed properly.What happens if you need to change a fuse in an emergency.
Thanks for any replies

I have 2013 C4 Picasso II. My heated seat stop heating. The drivers right side. The left side is working. Also the button for heating is black - no light. On the other side it has a light.

My 1st, thing to find a fuse. But there is no mention in the handbook. Does anybody know something.

I have a new info about heated seats.
At the night when all lights are on I see that my right seat SWITCH for heat is working. I put it on 1 and it stays there for a minute or two. Seat is a little warm. But that is just switches off. The light goes off and stops heating.
If I put on 3, it goes off in 30 sec. And after it switches off I can not see the light on the switch. After 20 minutes if I restart the car in goes ON again.

Any thoughts what is going on.

I think it is not the fuse. But I hope is a relay or something , but don't know where to check.

OK. Been on Citroen service, they had to remove the seat and check all over and found that upper seat rest has a grid broken.
They ordered a new one, (50 eur) and will replace it.

At least it can be disassembled and it is not expensive.

On my 2015 C4 Picasso dashboard fusebox (No 2), there is a bridging carrier which supports three plug/socket cable connections. These can be pulled away from the bridging carrier and the carrier removed by releasing the right hand side with a flat screwdriver and pulling the carrier away. This leaves the plug/sockets free to be moved out of the way to get at the fuses. I would suggest the plug/socket cables are only secured on the carrier during manufacturing and serve no useful purpose other than that. The cables can then be stuffed back into the fusebox void when work has been completed.
By the way, how do I attach/insert a photo as I have some of the fusebox with bridge removed. I've clicked on the various attach and insert icons, but all they do is bring up a load of text such as...
