Window switch LED stays ON

[sharpster]

Hi guys, this is my first post here so here goes: i have a 94 cab and i noticed that my battery goes flat in about a week when i'm not using the car. I checked the battery and its fine, but i noticed that two out of the four window switches on the driver's door stay always on/lit (the LED light inside the switch). The same happens on the pasanger's door window switch. Has anyone encountered this before and has a pointer on what to check first?

Many thanks

Not even a hint on this problem guys? At least a direction to take in checking what can be wrong. Thank you

Just to confirm people are reading the post..... HI but I have no idea. Sorry

Led s use minimal power so on their own should not flatten a good battery quickly. can you disconnect power to them for a bit to see if they are the cause of the battery going flat.
Sorry I dont know why they are staying on but would see if i could disconnect them so as to eliminate them from being the cause of flat battery.
Ask if anyone else lights stay on are they meant to maybe for a short while are they by the door handle giving a guide light in the dark for example maybe on a timer thats faulty. I know that probably seems daft but car manufacturers do some daft things vauxhall for example when you unlock an astra the registration plate light comes on god alone knows why but it does look out for it in local shop carparks at night

Sharpster a good place to start would be to have a fault code reading via vcds (vagcom) or similar to hopefully track down the source of your power drain

check wiring looms in rubber boots in door openings as these chafe

My guess is these LED's should only be on with either the ignition, or with ther lights and the ignition, so possibly a stalk problem or ignition switch problem?

If you take a lead off your battery and connect a multimeter (set on amps) one lead to the battery lead, the other lead to the battery post, this will show what the current drain is.

then set about removing and refitting fuses one by one, you should be able to work out which circuit(s) are causing this. If not, move onto pulling the relays one by one.

There will always be some current drain for things like the ECU, alarm and clock for example.

Thank you for your replies guys. The battery goes flat in about a week or so if the engine is not started in the meantime.

Granted, the battery might not be 100% perfect, but the only thing i noticed wrong was the LEDs in the switches, which stay on all the time, day or night.

I will follow your advices and see what i can come up with once the weather warms up a bit, but thanks again.

Are they LEDs or are they filament bulbs? A filament bulb has a much higher current drain than an LED and I have a feeling that LEDs were much in their infancy at the time the car was originally manufactured and they may not have been fitted.

iirc, they are 'grain of wheat' bulbs, not leds.
