Door open/close sensor?

[SmoothAssault]

Recently I noticed that the footwell light and the red light that's visible when the passenger door is open have both stopped working. They may have been broken the whole time I've had the car and just never noticed.

Little things like this annoy the hell out of me so does anyone have any ideas of what it could be? Faulty door open/close sensor? (if such a thing exists?) or some kind of button that is depressed when the door is open (like in your fridge?).

I checked the bulb in the footwell and it's fine, it's just not getting its 12Vs, it's got me stumped. I've got a horrible feeling it may have something to do with the water in footwells disaster that I fixed several months ago. Could the water have broken something?

Thanks guys.

Also, the main light in the roof that should come on when the door is opened; doesn't come on when the passenger door is opened. It only works when I open my drivers door.

Sound like a faulty switch for the passenger door which is in fact in the centre pillar.

I thought the B5 front door contact switches were built into the door catch mechanism?

I haven't got any front door contact switches for my front doors on the B-pillars.

May be I'm getting mixed up with the rears being in the rear pillar by the door.

Mine does the same thing on the drivers door. Seems to be ever since the door card came off, if I have the door card hanging off and move it around I can get the lights to come on, but it's tempremental and when I screw it all back together they don't work again. So seems like a broken wire/faulty connection somewhere, but can I find it? Not a chance, so would be interested to see if anyone comes up with anything, I gave up, can't locate where the door open/close sensor is either.

The connector is a 4-pin plug, on the door catch mechanism.

Very fine pins too...

My footwel lights weren't working when I got my S4. After a lot of head scratching and mostly some help from a fellow forum member shineydave it turned out I had a missing relay!

Any chance of some photos of the missing part/where it's supposed to be? I'm having trouble following the those threads without any pictures to help me.

Thanks for the replies guys.

Page 2 of the RS246 thread explains all (with a pic). Bascially a relay panel further up behind the relay panel you will easilly find if you remove the drivers side under dash panel. You really need to get your head up there to see the second board.

Thanks, I'll search and see if I can find it.

No luck searching for it. Any chance of a link? Thanks.
