Hope someone can help, before I lose all my hair. My daughter has my old renault Espace, 1994 2.1turbo diesel and the lights are driving me crazy. When the lights are switched on all the lights refused to work, no sides, dipped, main, tail or fog. It cannot be a fuse as everything is dead. when I opened the fusebox to look for a relay everything came on again, when i closed the fusebox they went off again. A connection!! so I chcked all the connections and nothing I suspect a relay is cutting the power for all the lighting. when I checked the feed to the light switch the red wire had 12 volts ok but when I switched the lights on the 12volts have gone. That was enoughto convince me I need some help. Sorry to be so long winded but I am trying to give as much info as possible any help will be appreciated
