1990 Mercedes-Benz 300D Questions
Would like to know how to check the current and working condition of the glow plug relay before buying a new relay or new glow plugs. Plugs are 3 years old.
My question is on using the service .
My interior light does not come on when when I open either door. The light does come on with the light switch. Is there more than one light in there and how do I get to the bulb(s)?
