The cigarette lighter in my vectra does not work, which I am not happy about as I need it for my GPS system. I have checked the fuse and that is fine, but don’t know the wiring diagram. Any suggestions?
Try prodding the centre conductor in the socket with a 12 volt test lead to see if theres power actually at the socket (careful not to short the socket out tho!) It may just be the heater element of the lighter thats gone O/C on you. HTH
