boxer wiring/relay diagram

Unread post by jasper3055 »

Has anyone got a link as to where I can get the wiring diagram for aa Boxer 2009.
I can only find the fuse box layout on line but there is a lack of information as to where the relays are i.e. shows you pictures of them but does not tell you which one is which.
I am also looking for the relay for the electric windows
Any help would be apprecated

It’s very likely tat the relays are integrated into the fuse box and not user serviceable.

Pop your VIN up (automasked on post submission) and I’ll have a look,

The relays are replaceable as I have been pulling the out looking for a power drain. Unfortunately the van is away at present so I don't know the VIN off hand.

There are quite a few variants of these - but they are essentially Fiat Ducatos, so have different electrics to proper Citroen / Peugeots, so as you say have more accessible relays.

OK Thanks for going to the bother to find this for me.
However it does not show me the relay which controls the drivers side electric windows.
Do you have any idea where this will be located?

Thanks. I have removed this relay when testing for the power drain. No effect. However I then thought I would try removing fuses when the engine was running to see how much current was being drawn across each fuse. I found that fuse 47 (power windows) had a reading of over 10A even although the window motor wasn't being used. I compared it to fuse 48 (passenger window) and got 0.2A. The fuse wasn't blowing as it is rated at 20A so where could this continuous loss of current be leaking from?
This drain is the same amount when the engine is switched off .
However when I pull fuse 47 with the engine off this has no effect on the drain, it is still there.
I also noticed 0.6A being used by the central locking.
Do you think that the wiring harness from the back of the BSI unit could be chaffed at some point?
The van is away at present but I will have a look at the window motor when it returns unless someone out there can solve this riddle.
