Hi lads,
My 406 hdi coupe rear lights and front side lights have for some unknown reason stopped working. At first they were intermitant,then every time i would close the boot lid the back lights would go off. I have checked the fuse box, light conections around the back lights. I still have brake, fog,and indicators all working on the same light clusters no problem. I am left scratching my head and thinking am i missing something simple.
Can anyone shed any light on it please?

No idea if the coupes too suffer with this but is the driver foot well damp / wet at all? I know there are multi pin connectors under there that if when they get wet can cause mayhem with lights - though I thought that was just brake lights, it would certainly be worth a look.

Other than that, sounds like a wiring fault of sorts with the units themselves, are they sealed in securely i.e no drips or leaks?
With my estate I have had a bit of a nightmare with a rear light unit letting in water which then fills the tailgate trim of water, amazing they still worked in my case but definitely again I would rule it out!

Other than that - I'm out of ideas! Best of luck

406 back lights not working

Thanks for the reply.
The footwells are dry but i wil check the conections.
When the car is started the rear lights do come on for 10 to 15 seconds then a 5 second sqeeking sound occours from mid dashboard behind the radio area and the rear lights go out. The indicators, brake, and fog lights still work though:confused:

I don't know what else to suggest, maybe get a multi meter, check the current going through it and see if that changes after the time frame? Could be shorting out somewhere or something.. I'm just guessing of corse!
