Lack Of Courtesy!

Post by tim leech » Sun Jul 16, 2006 11:55 am

Guys the courtesy lights dont work on the GTi I bought from Cavmad, they do when I turn them on manually but not when I open ANY of the doors, yet the door open display works fine!

Any ideas?

:shock:

Mines like that, I blame a previous alarm installation.

It had a moss alarm on it at one time, the 16v is the same and that had one too once! Any cure?

Probably a new alarm :cry: My remote locking is the same on the BX, it seems the alarm fitter hacked in all over the place, I have removed a lot of it, thankfully I can find my way around my BX in the dark :)

Hi Tim -

The door open warning lights panel -
&
the courtesy light door switches circuit -

Has NOTHING to do with each other. Not even the same earth point or fuse :wink:

All BX'es fitted with PLIP remotes have the courtesy lights timer feature. This is a relay look-a-like device. The timer takes the door switches inputs for activation - and of course a control signal from the PLIP.
It has a relay switched earth output resembling a door switch is activated.

From Scandinavian owners the experience is that the relay itself has a habit of developing breaks in the solder joints holding plug contact pins. Simply solved with a soldering iron.

Now where is this relay located ?
On LHD cars the relay is located way up behind the glovebox - which would be somewhere up behind the instrument clusters towards the drivers door on a RHD.
If you find such a relay looking device with a brown 7pole connector - you've got it.

As Anders says the courtesy lights and the door open lights are entirely separate circuits.

The courtesy lights rely on earthing through the switches in the door shut faces. These switches cost £1.50 from places like GSF and you may be able to clean those on the car.

Open a door, take a switch out (1 screw) and earth it and see if the light comes on. The lights may even come on if you fiddle with the switch itself while its still on the car.

Being a GTi - as Anders says the lights will be powered by a delay unit.

Strange that they dont work from and of the doors, yet the 16v ones work on the back doors only :shock:

They still earth through the door switches - that's the ones in the door shut face - and at about 12 years the switches corrode badly.
