Hello, so I bought a '92 loyale 6 weeks ago off craigslist, 240k mi on it. Its my first car and I'm really excited but a couple weeks ago the tail running lights went out and I got pulled over. I replaced the bulbs, still out. Brought it to a mechanic and after checking some stuff he is hesitant to start checking wires for shorts. He doesnt have a wiring diagram and cant find one online. I know little about cars and less about car wiring, so any help is very appreciated!!
More info:
-All fuses were checked by the mechanic and are good
-Headlights work
-Mechanic removed headlight switch and all four of those copper switch things move and get power
-Mechanic also checked tail sockets for voltage, brake light side works but tail light side doesnt, he said.
-Hazard lights work (besides front left)
-Car battery is from 2014, has lower but okay voltage according to walmart battery test. One of the two O clamp things on the battery is cracked and I'm going to replace it.
-Went to start car a couple mornings and battery was dead, but could start up immediately after jumper cables were connected
-Dome light is out
-Front left blinker is out
-Dashlights just failed a couple days ago
-Cigarette lighter doesn't convert power or heat up. This is important because I need to plug a converter in.
