We had some electrical trouble with our E350 class C.  The dome cab light stayed on all night and day, meaning a boost needed to start the engine. I’ve been disconnecting the battery overnight to prevent current running down the engine battery.

Yesterday, we found a better fix.  That light goes on when the driver’s door is opened.  The switch looks like a black button sticking out like a ballpoint pen.  It needs a squirt of penetrating oil.  And leave the headlight knob turned completely anti-clockwise.  If you need the dome light turn it clockwise.  Better yet replace the power eating bulb with a LED.

There is another switch on the passenger door. I will need oil, too.
