I have a 96 Xantia 1.8l 16v. For the past couple of days, the bulbs that light when you open the doors remain on after you close the door and put the key in the ignition, resulting to dead battery. The electrician told me that there is a problem with the time relay that keeps them on for ten seconds after you close the doors , but he couldn't find where the stupid thing is. Any suggestions?
