No tail lights on 2003 Kia Spectra
the tail lights just stopped working, brake lights and headlights work fine. no power to tail light fuses under hood nor inside panel. Where does the power come from so that I can start tracing it. Starter and Alternator are working fine, just don't know where to start on this one. Any kind of help will be greatly appreciated, Thanks JV
Test for continuity through the light switch.
check for "brown power" for A.) a battery older than five cannot hold it's own.B.) the Black cable connection wirebrush the lug and the chassis to remove all corrosion and put them together to restore the full 12.5 volts to operate the ECU and the fuel pump relay....etc....and tail lights...the chassis ground needs to see the black wire off the bulb..y'know~
