Title: Brake lights stuck on when headlights are on!!!
Post by: Sabs on 12 May 2008, 15:30:04
Dear All,

Im new to the frum; have a V reg 2.5 Elite with the works attached to it; its an AUTO but has a few niggles i need your help with please.

When i switch on the headlights, the brake lights stay permanently on!  But with the headlights off; they operate correctly!

Do you guys have any idea of what the problem could be?

Also, the AUTO gearbox has a mind of its own i think.  Ocassionally it will come up on the dash as "Auto Gearbox" and then it wont select any gears i.e stuck in third i think; once i swthc it off and on again; its fine, Ive had the module changed, still to no avail

Any helps guys would be greatly appreciated

Regards

Saboor

Check the rear earth, its behind the plastic trim on the boot slam panel on the passenger side.

Behind the rear panle in the boot - as in where the spare tyre is?

And yes the high level brake light stays on tooo

How could an earth casue the lights to stay on i wonder; though i will check asap!

Ill report back with the findings; take it off givei t a good clean and see what goes from there!

i cant see it being the brake switch staing on; as when the headlights are OFF, then the brake lights perform correctly!  So it cant be the adjuster being too loose!

going to check the earth; car is out at the mo; see what goes!

i sound so bloomen stupid saying this; but is there an auto box dipstick?  i havent really seen it tbh anywhere in the bay; but will look on the pics provided by the site and locate it; will let you know.

Its only when i move the selector around from reverse to drive to 3rd; all the selector lights come on and then the fault message comes on the display!

Do the headlights come on when you apply the brakes??.    If so it could just be a bulb in wrong or incorrect bulb.

check that you have not got a single filament bulb in the brake light holder this can also cause this to happen silly it sound i know but has been known. It is where the single bit is making a contact between the 2 prongs.




LOL lee we posted at the same time.

I'd almost be willing to bet it's either the wrong bulb or fitted the wrong way around! I wish people who don't know how to fit atlas would learn! It's hardly rocket science!

Oops... Sorry, that sounded like a rant! :-[ :-[ :y

if its a bulb; honest guys ill slap myslef and then allow everyone you gys to do it too!

Ill admit, im a bit scared now, because i did change the bulbs on both sides; HOWEVER; i ensured i bought the correct bulbs from the halford in store guide; now lesson learned, i shall go to VAUXHALL and see if it makes a differernce, they are only bulbs so wont cost a fortune!

I know what I'm after and still find a lot of these Guides confusing!!

Before you rush out for new bulbs... Take the old ones out and try turning the lights on... You'll get Headlamp/Tail lamp warning come up but if the bulbs aren't in then they can't complete the circuit!!

We might be wrong but that's the most common problem... Quite often they get forced in the wrong way around (offset pins dictate correct orientation of bulb in holder) and can short across both pins!  :y :y

Oh, and I wasn't having a dig at you by the way... My pet hate is people who change headlamp bulbs and manage to get them in the wrong position so they blind every other person on the road at night!!  >:( >:(

Went to vaux dealer in the local area after searching them down via Yell.

Anyhoo; even they were baffled by the light arrangment and said that my car should have this, i went shut it and get me these bulbs please' to which he returned with COMPLETELY DIFF bulbs to what i had in the car.

So put them in and WAHEYYYYYYYY  ;) it works fine now.  Brakes arent stiking on and all working well!!!

But got this for you guys to look at:  when i was putting the bulbs in under the carpet this came to my attention!

the blind and rear speakers work fine; so where is this supposed to be connected to then:

Pleased to have been of assistance!!!  :y :y :y :y

As for the lead... I've got one of them floating about too, but mines up by the amp, with the rest of the loom! The only thing that doesn't work on mine is one of the door speakers, which I'm pretty sure is blown.  :-?
