Interior Light - weird fault

[dmdigital]

My wife has reported a rather strange fault in the Puma today. As she drove along the interior light at the front would come on then fade out and a while later repeat this and so on randomly. I took the car for a drive after work and found the same thing. It doesn't do it when the light is set to OFF or ON, only when on door setting.

:confused::confused::confused::confused::confused: :confused:

Never heard of this happening before so I'm rather confused. The only thing I can think of is an issue with one of the door switches. I had to realign all 4 doors last weekend to install the checker plate, so perhaps one of the doors isn't pushing the switch in sufficiently.

Anyone else come across this fault?

That was my first thought. Try isolating them one at a time to see which is the culprit.

Good idea re isolating each one... You havent caught the wire sheathing have you, thus causing a short? I think the ECU controls the delayed dimming function, so it would only take a momentery short to give the effect you are seeing?

I dont think moving the doors up 1/8" to allow for the chequerplate would stop the light switch working. The switch striker plate is quite large so the doors would need to me moved ALOT to stop it working.

They were moved up at least 1/8":eek:
I think - when it stops raining - I'll be trying door by door to see what I can find.

try using duck tape (sticky tape) on 4 of the 5 doors' switches. rotate from 1 door to another until you find the problem. I think sunny day or rainy day doesn't matter for this test.

You've adjusted the Defender doors from the factory positions !!!:eek:

I certainly hope not as these are a precision fit & they spend ages getting each Defender perfectly right on the assembly line.

It does when it's bucketing down and I have to do this out in the open as I don't have a garage.

Yes, hard to believe! I did put the dog inside the car and close the doors, but she followed me back in to the yard all the same;)

As others have said, it'll be one of the door switches. I had the same trouble after I got my side mirrors tightened under warranty by the dealer. (this means loosening the hinges to get at the mirror screws!)

They had to check all the door switches and found one where the wiring was touching the body at times. It was OK until the door mountings were disturbed during the mirror tightening.

Hope it's only a small dog!!

The land rover factory setting is that a cat should be able to get out, so provided you only have a small dog, all is probably OK :D:D If you have an Irish wolfhound, then back to the drawing board.

She's a GSP so medium sized. I wouldn't want a small dog in a Defender. If it was sitting on the floor when you were driving along it might fall out.

I suppose if I had a Boxer I could use the drool to check for leaks around the door seals :angel:

Just an update.

The latest quirk is that when I get out - down the shops - and press the lock button on the fob, the horns sound for a miss-lock. It's very LOUD:eek:

Anyway, I've now traced the fault to the driver's door. If I hold the switch in everything is fine. I've now unscrewed and jiggled the switch, put it back and all seems OK for now.

[dullbird]

at least you got a horn part of ours isn't working so when you hit it coz someone has cut you up or somthing its sounds like a friggin noddy car....and the people you are beeping **** them selves laughing :lol2:

[dmdigital]

That sounds like one side is not connected. Check the fuses as they may be off separate fuses and check the wire(s) to the horns. There's one on each side in the vents under the park lights.

Easiest way to check is get Ian to place his head down low near one of the head lights and you toot the horn. Then repeat the process on the other side and see whether he can notice any difference - of course he might go deaf too:angel:

Didn't forget the blu-tac I hope? ;)

Derek,
It will be the same fault causing this. The alarm ECU also works off the door switches. It see's one of them open...the faulty one...& thinks the door is still open & a mislock alarm is heard.
Also from memory the Alarm horn is different from the normal 2 horns..
Will clarify this as on the D2 it is & from memory i recall seeing a 3rd horn in the Defender.

Cheers.

[dmdigital]

Thanks Pete, already new about the switch being for the alarm and light. Don't know about a 3rd alarm horn. There's one on each side at the front of the Puma, can't recall seeing a 3rd one though. I can tell you that a miss-lock is a lot louder than it was on the Disco:eek: Scared the daylights out of me when I pushed the button the first time it happened.
