Thread: Interior Light - weird fault

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.

Mark.

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"
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 !!!

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
