The dome lights on my 2011 Ridgeline will not come on when the door is opened. It is not the on/off rocker switch on the dash. The lights on the door edge do come on as well as the light in the back seat at the base of the console. Any thoughts where to look? It did this once before, then worked for a while. Now, no lights. If it is a ground problem, where do I look? Fuse is OK.
