Hi. I'm wondering if anyone can help me troubleshoot an issue I'm having.

The courtesy lights (in the doors, the rear dome light, and the boot light) all come on when I open the tailgate if switched to "door". The dome light and boot light also switch on when I manually turn them on. However, opening any of the driver or passenger doors does not turn on the lights (either in the doors or in the ceiling), even when switched to "door".

Can anyone advise if there is something obvious I can check? I have checked fuses, but they seem fine and in any case the lights are fine when the tailgate is open. I'm new to landcruisers, and I'm stuck, so I'll gratefully investigate any pointers you can offer.

Thank you.

Hi Steve, thanks for this response. I probably could/should have been clearer, so I'll have another shot in case it helps your understanding or diagnosis...

Our LC has three sets of lights in the ceiling, which I'll call:
1. Front dome: this is two separate lights in in the front, which each just have an on/off switch.
2. Middle dome: this is three lights above the passenger seats in the middle row. The centre light has an on/door/off switch, while on each side there is a light, each with just an on/off.
3. Boot light: this is in the boot and is a single light with an on/off/door switch.

In addition, there are courtesy lights at the bottom of the front and rear doors.

I'm terms of behaviour:

If I open a door (front or rear), none of the lights come on. But when I open the top half of the tailgate, the centre light in the middle dome, the boot light, and the courtesy lights in the two rear doors all come on.

The front dome lights come on if I switch them on. And the courtesy lights in the front two doors have never come on. I've checked all the bulbs.

I did wonder about door switches, but assumed they'd all have to be broken to cause this behaviour (which I guess isn't impossible at this age). Are the switches located in the door catch?

Is there any other obvious fault finding out diagnosis anyone can suggest?

There is some kind of a timer - the lights go off after a certain time, and if I come back to it after a while, then sometimes (couldn't say under exactly what conditions/times) the lights won't come on until I turn the key in the ignition to switch the electrics on. The vehicle is new to me, so I've not seen any other behaviour prior to what I see how.

Thanks again for the thoughts so far.

Best, Jon

Hi Steve that's super helpful thank you. Good to know what the intended behaviour is too.

I'll check out the switchesin due course (wife and kids are on the road in it this week so will have to wait until they are back...)...

Thank you - again much appreciated!
