Re: IML: 60 Dome light stays on

["Rob van der Es" <R.vdes@xxxxxxxxxxxxxxx>]

Thanks Joe and Paul!,

I certainly won't give up on this one :)
I already discovered a couple of wires with brittle insulation and have 
replaced them.
However, the right one was not amongst them and the light still shines at 
half power.
But don't worry I still have a lot of wiring to check, now I am there I will 
check all wires on all doors. I don't trust this brittle insulation any 
longer you see!

I will keep you all updated about my progress :)

Robert
