Hello, I have a used 04 Murano se and have a rather weird problem. My "vdc off" and slip lights never illuminate even in key on, engine off. The light also never illuminates when I press the vdc button leading me to beileve the system has somehow been disabled. The chances of both the slip light and "vdc off" lights in the dash both burning out seems to be pretty unlikely. Is there any way someone could have done this and any way to bring it back? The car does occationally clunk in the rear when making turns but i'm not sure if this is related.
