I assume that you've checked there's power to the door switches and also the light? I would imagine that if there is a relay that it'd be under the drivers seat.(can't guarantee it though) Also check that it isn't the switch it's self that's at fault. Is this on a Puma?

I once found that the rear door switch on mine wasn't working and there was power there. Took it out pushed it a good few times and played around with it a bit and a small touch of oil and worked perfectly then. Must have jammed.

I thought there is always power to the interior lights. The switches are in between the lights and the negative (earth) so may be there is a earthing problem... Cheers, Vincent

I didn't know that  Regardless the circuit needs to be checked that it isn't broken. Fuse would also need to be checked. But I have no idea of location off the top of my head  |

I have found that the switches on all LR products get a bit of blue crud between the contacts of the door switches and with only one screw holding the switch in place it is an easy fix. 2008 RS4 gone, 123d M Sport, and a Puma 90 XS..

Got a feeling it's copper verdigris that get to the when there's wet weather. |

I have had all the door switches out cleened up and coated in vaseline also when out I did a test on them with a multimeter all perfect I have a constant power to all lights and they both work when switched to on but still nothing with the door pins the only other thing I have thought of is they run thro the alarm ecu maybe there could be a problem around that area

As has already been said, there's no live at the door switches. The door switches switch a Purple with Blue trace wire (Grey with White trace for driver's door) to earth. This signals the Alarm ECU to turn on or off the interior lights. The Alarm ECU does this by providing an earth path for the interior lights, which have a permanent live to them. You can test the functionality of the Alarm ECU by earthing the wires at the door switches, this should switch on the interior lights. Download and have a look at the Circuit Diagrams (pages 54,55, 58, 59 & 60) that Danielle has made avaialble, here - http://www.defender2.net/forum/topic11725.html .

Just a thought, the interior light switches off after a certain time to preserve the battery. If one of the door switches is permanantly shorting the Alarm ECU signal wire to earth (OR there is a short on this wire and it's permanantly grounded somewhere) then the alarm ECU will have switched the light off to preserve the battery and until the earth (or short) is removed from the signal wire that alarm ECU won't reset.
With all the dors closed my suggestion would be to check if the alarm signal wire is permanantly shorted to earth Another test would be to try and disconnect the signal wire from the alarm ECU (I've no idea where that is!) and then reconnect it to see if the interior light comes on for a couple of minutes before the alarm ECU goes into battery saving mode again Carl MY11 110 XS Station Wagon in Stornoway |

Forgive me for asking the obvious but you have got the switch on the light fitting in the "remote" position, the light fitting switch is 3 way, 1) ON, 2) OFF, 3) Remote.
By the fact the light is working locally, then you do not have a supply / fuse problem, the light only has 1 fuse that is located in the fuse box under the steering column. For all three door switches not to be working sounds doubtful, but if you have not already, try removing a switch, disconnect the wire and short the wire to earth, ensuring the light fitting switch is in "Remote". If that doesn't work I would remove the light fitting and test the fitting switch, if that is ok, it sounds like you have a broken wire somewhere between the fitting and the remote earthing points, i.e. Alarm and door switches.

Have you replaced the bulb recently? Just thinking that when I replaced mine, the light would work ok if switched it one for the light switch, but not from the doors opening. Turns out a wire had popped off the back of the contacts when I removed the light to change the bulb. 1999 Defender TD5 110

Hi, I had a similar problem when fitting interior LED - blew the fuse. Replaced the fuse in passenger compartment and light working again, both from doors opening or on manual switch. HOWEVER, the interior light now only works when the ignition is on, whereas I'm sure before it used to work as soon as you opened the door. Any ideas? Thanks, alan

Hi, can anyone advise, is there some sort of secondary circuit that keeps some things powered up without key in ignition. Since I blew the fuse in the passenger compartment (and replaced it) the clock only works witht the ignition on and the radio loses its presets each time ignition is off, as well as problem mentioned earlier where interior light now only operates with Ignition on, not as soon as door opened. It's a 1999 TD5 90' thanks, alan
