Good Morning

Any help, comments, thoughts on the following would be greatly appreciated. This has gone past the 'tearing my hair out' situation!!

Fault: As soon as you open drivers door the dipped headlights come on (on their own, no key in ignition). The lamps stay on for random times from 15 mins to 2 to 3 hours. The lamps dip or main will not operate from the headlamp switch either. Windscreen washers and heater fan also not working. Now I know problems like this are common on the Peugeot/Citroens but this one has me about to throw the towel in.

No fault codes were stored on snappy Verus. Checked for the usual water leaks, wiring chafing etc. Tried bsi reset, nothing worked. So in the end van has had new bsi unit and under bonnet fuse box. Fitted the fuse box and then van went to local dealer to 'code' in the bsi and they rang me to say it hadn't cured it. I then asked them to see if they can diagnose problem. They also drew a blank. Van then went to local Auto Electric specialists, they had it for weeks and still cant find out what is wrong with it! (they tried headlamp switch/module on it, renewed earth contacts to nearside headlamp and cleaned up/made good connections).

Help! Not sure whether to go down the wiring loom route or are we missing something silly? Or could just turn it into an ashtray!! w00t

Thanks in advance

Bill

I've had this before on a Peugeot - only problem is I can't remember the cure.  It wasn't a very long job, so a blown fuse comes to mind.

When dealing with weirdness; pick one simple fault and concentrate on that - like why doesn't the washer pump work?  The diagram suggests fuse 27?

Has this one got a Comms 2000 or does it still have manual switches?

Has it got automatic headlights?

Read your post on your problem with your berlingo van,
I had one in with the same problem, head lights coming
on when you open door and heater fan and the only way
to turn them off quickly was to turn the ingnition on,there
was resistance on the White and red can wires between bsi
and engine fuse box mine was in the White wire just about
12inchs from front fuse box

Just fixed one today and it was the exact same wires and area as above post!

If your Citroen Berlingo or Peugeot Partner 2003 (1.9 WJY engine and possibly similar), headlights stay on and heater blower and horn do not work then it will probably be due to the two Can Bus wires (red and white twined together) which run from the black fusebox under the (UK) driver steering wheel (Bsi module) to the passenger side engine bay fuse box which is also the Bsm (another body control module).

You'll probably see in the engine bay near the passenger side headlight area, that the wires have gone green in an area about 12 inches from the plug (which is top left in the engine bay fuse box).  Remove what's left of the insulation and then cut & re-join the wires, removing the corroded area.  It should immediately fix the above problem.  We were told it was a Bsm module (which thanks to lazy Peugeot Breakers was impossible to find, and cost £400 brand new).  Thanks to Peugeot Planet 2000, I was able to see the Bsi Fault code.

Hope this helps you, internet Peugeot owner!  Thanks for the above post.

Welcome to the forum.

Thanks for posting that valuable info - if confirms what looks like a common problem that may come up again.
