Vauxhall Vectra GLS 16V - 1999
My head left hand head light failed last week and now the side light has too. I have changed teh bulbs & fuses but still no joy. Right side is OK, I dont have any voltage coming through either. What do I need to check next

thanks guys, where's the relays?

hi pau

it sounds like an earth problem check the relay and wiring at the back of the headlamps especialy the earth leads usualy black wires it could also be a connection problem due to corroded connectors disconect spray and clean with wd40 reconect try again do your indicators light up when your side lights or headlights are on ?
if so replace the relay
hope this helps

I think you need to check out the headlamp relay to see if its failed....not to sure about the sidelamp though!
