I'm having troubles with the brake lights in my 97 Impreza wagon. The left brake light went out. It looked like the contact in the socket had overheated and melted back down into the socket, and lost contact with the bulb. I replaced the socket assembly (in fact the whole rear light combination, since its all on the one connector), but no dice. The right one is out now as well. I am getting 12 V to the socket contacts, but the bulbs aren't lighting up. All the tail lights and turn signals work.
However, the plot thickens, because in the last week, I lost the horn (blown fuse, replaced and still working), cruise control and dash illumination. This all points to a short...somewhere. I am getting the service manual (ie wiring diagrams) as I type this, but does anyone have any suggestions?
