GeeBoy Posted February 16, 2011 Share Posted February 16, 2011 I recently purchased a 93 SC400 and the brake lights dont turn on when I turn on my headlights. They come on when I brake but not when im driving regularly at night. I changed the tail lights thinking that one of the filaments was burnt out but no success. I also checked the fuses which seem to be fine so I am mind-*BLEEP*ed right now. If you folks can help me out I would appreciate it. Thanks Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted February 16, 2011 Share Posted February 16, 2011 Have you tried using a basic test light to see if power is getting to the taillight pin of the bulb sockets? If power is getting to the tail light pin in the bulb sockets, the problem is likely a bad ground and you would then check the ground wire connections in the trunk.

GeeBoy Posted February 16, 2011 Author Share Posted February 16, 2011 No i did not try that yet. Thanks for the input. Im used to having things just work but this project car is really keeping me busy. Quote Link to comment Share on other sites More sharing options...
GeeBoy Posted February 17, 2011 Author Share Posted February 17, 2011 Yesssss!!!!! Finally found out the issue. For some dumb reason the previous owners removed a relay controlling the lights from the kick panel. Restored functionality to tail lights sidemarkers and corner lights. Thanks to all those who gave me tips. Quote Link to comment Share on other sites More sharing options...
