Interior directional lights on 2005 Mercedes-Benz C320

Directional lights on the outside of the car work properly. But the directional lights in the inside of car are always on--steady light--even when car is turned off. Lights have been constantly on for last 4 months. Also change in directional lights on the outside are not noted on the inside--lights constantly on.

There may be a fault in the instument cluster itself- it is a small computor of sorts. This will require diagosis by a dealer or well staffed independent service shop. Best of luck, Greg
