Peugeot Partner, intermittent lights don't work

Hello,
good afternoon, I have a Peugeot Partner 1.9 Diesel Mod 2005 (Argentina). My problem is that the flashing/turns/winks do not work for me .. In the witnesses of the board they will quickly stand as when there is some molten focus, when I turn on the beacons you are in the witnesses of the board light to the normal velozity but do not work externally, check the spotlights and they are all ok, check all the fuses of the habitaculus and are ok ... beacons .. change the key and still have the same problem .. Then I have to change the relief/flash but my problem is that I do not find it near the Bsi rifle. and a friend told me that this partner model has the relief/flash incorporated into the BSI .. does anyone know if this is so? And how can I solve it?

Thanks, Gastón

Before continuing to change pieces, check the ground cables to see if anyone is disconnected or lazy or sees if you have any connector do not make contacts locked them if you have a cleaning spray you use it and you connect it again.-You have those tests and let me know

Tomorrow I am taking it to the mechanic, it is that I am not and I give myself a bit of a morning but not so much so that then notice what the solution was in case you can help someone in the future .. Thank you very much for your opinion. Greetings Gaston

Hey luck but check at least only the ground cables because for what you explain to me, it must be some loose connector, check if they do not work on a single side or on both

Gastón, I have a 2004 Diesel Berlingo and the same thing happens to me .... could you solve it? What was the problem? I took him to an electrician and did not find the fault.
Thank you.
Gabriel
