Help! Boot interior light won't go off

[tomto]

I bought a 2009 EX a few months ago and I am having a problem with the interior rear light. It won't turn off!

Symptoms:

A couple weeks ago the "boot door is open" warning light came on as I started driving but the boot door was closed. Tried opening it and slamming it shut but the light came on again. It went off a few seconds later and hasn't shown up again since.

At the same time the 'lock' function on my key fob doesn't lock the car anymore. The 'unlock' works fine.

A couple of days ago the battery was completely flat. I replaced it thinking it was old and dud. After replacing it I double checked lights and things to see if anything was causing battery drain and discovered the boot light to be on even when the boot is closed. I removed the bulb which I hope is enough to stop the battery draining again.

Why is the light always on? Is the door not registering as being closed? Is there a way to fix this?

Any help is much appreciated!

The doors won't lock if any of the doors (including boot) are open.

It sounds as if the boot switch or the connections to it are going bad.

It's either your local dealer or a car electrician for a fix if you can't DIY.

The switch that tells the car the boot is closed is faulty,  this affects the locking and the boot light.   The spring loaded switch contacts are normally closed with boot open, turning the light on and are forced open when the lock mechanism pushes on it ( the D shaped hasp on bottom of tailgate opening pushes the white plastic bits in the lock mechanism into the right place when tailgate is closed, allowing it to be locked ), turning the light off and telling the locking system that the tailgate is closed and can be locked.

The switch is part of this ( see attached PDF photo ) -  the switch closes the circuit by switching wire down to bodywork, so can be a short on a wire in there.   

You will probably have to remove trim panel inside tailgate to access the switch.... never had to do it so cannot help with that bit.

As a temp fix, once you are able to access the switch, you can just pull one of the wires off so the switch (and the car) "thinks" its closed.

Thank you all for the replies. It seems I can leave it for the meantime and the battery won't drain again right? (off on holiday next week). I'll give that fix a go when I get back.

If the light is off, you're OK. If the light is on, it'll probably drain the battery if you leave it a few days.

I've had problems with my Mk2 when the passenger turned on their interior light, I didn't notice and then both lights came on when I turned off the engine, and because I was parked under bright street lights I didn't notice that the light was still on inside when I locked the car. One weekend later and I had to charge it on an extension lead for an hour or so to get enough in there to be able to crank it. (I now have a little Li-Ion booster battery for such an occurrence.)
