I have an ex-British Gas 2005 medium roof 330SWB, purchased May 2010. Love it, but have a rear interior light problem. When I first got the van, after about a week I had to keep jump-starting it. When I had time to look, the telescopic hinge switch (about 4cm long, 3 or four sections had been bent towards the van interior, so was not retracting and turning off lights. (not surprising as it was so long). Took it to garage under warranty, as it had a seperate problem too (starter motor was replaced as van had juddered to a halt in heavy traffic and died). I presumed batterry had drained/died as bent switch had pulled off connecting spade terminal. Got van back with empty hole where switch had been. Had to replace battery two months ago, but already having trouble starting again. Discovered rear interior lights only go off when I lock with fob remote, otherwise lights are on as I ignite/drive/ etc. Pain as I have to lock when working, even on a private driveway, plus if I'm double locked in, no-one can pull me or my lovely dog out of van in an accident!!
Might drop back in to sales garage, but did ask electician what he'd done and he talked fast and rubbish. Have tried attaching to still dangling spade terminal with wire, but when I ground it, lights stay on.
Anybody know what to look for next? Please help if poss.
Aaaaarghhhh
