    i have had LED's in my fro t doors for some time, I did try those projector lamps but only the drivers side would fit so I removed it and replaced the blue LED. Yesterday I noticed that this had failed ie it was flashing so I dug out my spares popped the lense and replaced the bulb.
    This never worked so I took one of the old white bulbs (that I had kept) and as I went to put it in it illuminated so I thought it's ok. So I got another LED / nothing.
    Swapped it with the passenger one which was working nothing.
    I tried all the bulbs in the passenger door and all worked bar 2.
    I decided to go with the original white bulbs till I could get some new LED's as I knew they were ok I put the bulb in nothing. The bulbs are fine. I took the door card off and removed the light fitment. I gave this a good check over all seems ok traced the wiring that seems ok. But still no power to the bulbs .
    Question is there a fuse that protects this circuit?
    Anyone think of anything else I can check?
    Thanks

    Check the fuse box in the engine bay, I think there is a "Interior lights" fuse in there.

    The LED bulbs are normally terminal specific - silly question but did you try them with terminals switched?

    Yes and I also tried them in the passenger side to ensure they were working

    Mick are you sure it's not your door switch playing up or sticking.

    Not sure I'm going to look at it over the weekend when I'm not working.

    I've just had a quick look and noticed when I open the door the interior light doesn't come on?
    If I open the passenger door it does.
    Fuse checked it's fine so I'm thinking either the switch or I may have trapped the wiring to the bulb holder I'll check tomorrow for power to that.

    Checked the door switch it's working fine I changed it with one of the back ones the front still didn't work, but what I have also discovered is that the alarm when you leave the headlights on is also not working??? Checked the wiring and as far as I can see there's nothing wrong with it. Any ideas anyone.

    Have you put back normal bulbs to see if they work ?

    Yes using normal bulbs that work I've tried them in the passenger side door. I presume this is a circuit that consists of the door light the interior light and the headlight chime when you leave them on and open the door. I've swapped switches bulbs fuses ?? Head scratching now
    I've even checked all the wiring and connections on the passenger side just in case they pulled something when they did the airbag but nothing.

    Just revisiting this one... did the normal bulbs work when you put them back in again or is the circuit completely dead?

    The circuit seems to be completely dead. I changed everything the original bulbs were OK tested in other door, I even changed the door switches round they were all working perfectly. I had the door panel off to check if the wiring had been snagged anywhere ,
    nothing.
    The only thing I haven't got is a ohmeter to check the circuit wiring to see if there's a drop in power anywhere.
    I was wondering if it's something that needs resetting somewhere.

    don't want to panic you but the MICU also controls the car detecting doors being opened.

    Get a voltmeter and check for any voltage or break in continuity

    I've got an auto electrician coming to have a look next week, I suppose this is an expensive part to replace?
