Electrical gremlin - brake lights - ginge191 - 03-11-2012

Brake lights arn't working on the 205 - completely stumped by this.

So the rear clusters ARE working (reverse, indicators, night lights and fog lights) yet the rear brake lights don't work.

Checked the fuse - fine
Checked the switch behind the pedal (multimeter tested) - fine
Checked bulbs - fine
Checked earth - only one earth 'plug' for the back and its intact and clean
Checked plugs and socket on rear brake light cluster - fine

Also, when any electric item goes on or activates when having the radio on, it interferes (ol'skooool), so for example, i turn the wiper on, the radio gets interefered, as with the headlights, fans etc - and is the same when i press the brake, so there is 'something' there, just notillumination at all.

any ideas?

Defo earth related bud well the interference is anyways run a couple of new fresh earth points and check the cars main earths

You have a cabin earth awry somewhere i expect - can't be too many of them on a 205.


RE: Electrical gremlin - brake lights - ginge191 - 03-11-2012

hm ok; i'll have a look around for any earth points - get the haynes out.

As said, the earth in the back was perfect - hence the other lights working, so is there likely to be another earth point in the front somewhere?


RE: Electrical gremlin - brake lights - C.A.R. - 03-11-2012

On a 306 there is an earth point in the drivers footwell for example. No idea on a 205 though


RE: Electrical gremlin - brake lights - vincent1 - 03-11-2012

how many wires are on the brake light switch if 2 can you link them together and see if the lights are on?


RE: Electrical gremlin - brake lights - Niall - 03-11-2012

Definitely sounds like a earth issue with the interference. Or that could be totally unrelated and you could just have a broken wire somewhere!

Either way, good luck!

Thing is, they worked for about, 10 minutes once when we first attempted to fix it - when they worked, all we done was take everything apart that i've said above and put it back together again... Confused

That's almost certainly got to be a bad connection somewhere, no?

Top marks; i knew there was an electrician in this forum somewhere... Dodgy

I know it's a dodgy connection as everything else is intact and it WAS working at one point, but checking all the points, i can't think what else to look at


RE: Electrical gremlin - brake lights - Poodle - 06-11-2012

Oh fair enough, i take it you've tested all the wires and refreshed all your plugs/sockets then?
