Hi I am new to the forum, i have a relay L3 H2 and the interior lights in the cab and the cargo area have stopped working. I was fitting a reversing camera and had removed the interior light cluster over rear door while fitting camera. Refitted cluster and did the same in the cab while running the cables. Before they where removed they had auto switched off. Now the lights don't work even if you manually switch them on or when the engine is switched off or when unlocking the van. Any ideas what could be wrong? Thanks in advance. Robbie
