Urgent Help needed

Post by mattyf »

Hi all,

I’m not very technically minded but my brake lights aren’t working and I’ve got a 15mile journey home. I’ve just changed the bulbs and that hasn’t done anything to help so I was wondering if it would be a fuse or something simple so I can fix it before the drive home?! :shock:

Cheers

Matt

My first guess would be the pedal switch has become dislodged. At the top of the brake pedal (you'll need to kneel on the floor beside the car for this!) is a bracket with a switch (two if you've got cruise control). It's just push-fit jobbie which if memory serves puts the lights on if the switch ISN'T pressed. The trick is to make sure the switch is pressed at rest but breaks the switch contacts when you push the pedal even slightly...

If you want someone to look up the fuse number you'll have to say if it's a D8 or D9 as they have different fuse layouts

sorry but how would I know which type it is?? It's a TReg if that helps.

I'm really sorry ... I will try that switch thing in a bit.

T reg means it's a D8... Hopefully someone around here has a D8 handbook/haynes to hand

T-reg can be either a D8 or a D9 - you're talking 1999 here, right in the transition period. My D9 is V-reg, made in November 1999 - but there are a couple of T-reg D9's in Aberdeen too.

Assuming your car is either a saloon or an estate, the best way to tell if yours is a D8 or a D9 is to look at the front of the car. If your car has a slatted grille on either side of the Peugeot heraldic lion badge, it's a D8. If it's a black honeycomb mesh on either side of the badge, then it's a D9.

As for your particular problem - I'd guess it's a fuse, myself, but the switch thing is entirely possible too - French electrics! :)

Yours is a D9, probably one of the last T-reg models, and definitely one of the first D9s.

I don't have any more information to offer you than that though. Do you have a handbook for the car? The handbook should show you the fusebox layout, and therefore which fuse to replace for the brake lights. If you don't have one, then there is a PDF copy of the D9 handbook available if you go to Peugeot's web page and sign up for the "My Peugeot" section. Hopefully it will help you out.

Look at the first two pictures.

It's hard to tell from the photos, but look just above the nut covered with blue threadlocker (I hope that's the brake pedal else I'm going to look daft here! :shock:). You can see a curved section (inverted 'U' shape bit of metal) attached to the pedal metal, and just above that you can see something shiny. I suspect this is the switch (or one of them if you've got cruise control).

The switch is NOT mounted on the pedal, it's on a separate bracket, and it's a pretty small plastic affair with a threaded bit (visible on the 2nd picture) where it goes through the hole in the bracket.


If you yank the switch from the bracket, with the ignition on, the brake lights should light.

Just though I would let you know I FOUND THE SWITCH (spending so much time on my head :? )!!! Went to Europarts, £5 later walked away with one and fitted it and guess what ... I have my brake lights back!! Thank you all so much!! :cheesy:

Nice one! I'm surprised the switch actually failed - can't recall one ever failing before. Usually they just get knocked out of position...

Glad you're all fixed up now :)

Yeah it is weird ... put the two sitches together and the new one stuck out just that little bit further and couldn't pull the old one out to match .. weird!! :frown:

My clutch switch failed which caused hesitation at low revs as it was cutting the fuel line as it thought the clutch was dipped.

The old one seemed "looser" than the new one.

Surprised it's not more of a common fault.

Interesting. I didn't think the clutch switch had anything to do with the engine management... especially since the switch works at the very top of travel (just resting a foot on the pedal should operate it) whereas bite point is a lot further down and is certainly not a binary operation...

The litimus test for the clutch switch was to disconnect it. It ran a bit better than it was, but had a tendency to stall when stopping.

Apparantly the clutch and brake switches control fuel getting into the car, cutting it off but allowing enough to stop the car stalling when the clutch is dipped.

For whatever reason at 1500-1800rpm my car wasn't getting the full fuel to drive without feeling like it was hesitating, so must have been in anti-stall mode.

(Mine is a 2002 HDi 90 Rapier with no Cruise control).
