ive checked fuses, lights, everything i can think of.. the only thing i havent checked is the switch. and its only blowing as soon as i turn on parkers, and its just that one light, it DID have custom wiring cuz the model didnt come standard with a wing/spoiler and mine had the standard lancer spoiler with the breaklight, but i ripped that out cuz it was all broken up with no lenses or anything. the brake lights work fine, its just the tail light that is causing a issue, which is why im replacing the switch to see if that fixes it, as far as i know, the entire dash is factory default which can cause problems since it IS a 17 yr old car and with all the original parts.. they do die eventually, its done well over 300,000ks on the clock and doesnt blow smoke, did have a few leaks in the engine and a screwed waterpump but the engine issues have all been fixed and replaced, im not a electrician nor do i know too much about electrical wiring harnesses on cars, my brother does all that stuff for me, he reackons replace the switch so im gonna do that n see how i go.
