SL/R230: Instrument panel lights staying ON

The car is running perfectly fine and I cleaned it up nicely. It wasn't until late this evening I realized that after parking the car and locking it the instrument panel lights and the clock are staying ON.
I am unable to understand as to what's going on.
I just bought the car about a month ago and it's a 2003 SL with 46000 miles on it.
Thanks
Paul
Can anyone confirm which SAM would need to be looked at for this? I couldn't find any specifics on which SAM or how to remove any of them.
thanks in advance
