Re: Interior lights on the blink

follow on from the interior lights staying on problem discussion ...

... I looked into the Bentley for the newer 5k over the weekend.  It shows 
that there is a *single* controller for the lamps, and the wiring is fairly 
simple.  All of the door switches are wired in parallel to a single input on 
the controller, and there is an input that is energized whenever the igni-
tion switch is in the ON or START position and another input that comes from 
the central locking system.

>From what I see in the wiring, I'd put my money a bad lamp controller unit.
Although it seems like it is a simple relay, there is a circuit board inside
and the circuitry has probably gone south ... If I had the problem, I'd prob-
ably try to take the thing apart and fix it before being forced to go out and
buy another one ...

To rule out a flaky switch you might want to leave several doors open ... 
the controller should shut the lights off eventually.  It would probably
be worthwhile taking a voltmeter to the pins to make sure that the LOCK
and IGN ON signals are making it to the controller as well.  

Hpoer this helps!
