Hi,

GS 300, 2002. My tail lights (outer) are not working (both sides). I had lights on while replacing a bad bulb and accidentally touched ground and source (+) with my screwdriver. I checked all the fuses, but all looks good. Is there a relay for tail lights? if so, where can I find it? Can someone provide a wiring diagram? Red wire (coming from that bulb ) doesn’t have any voltage. Thanks for help in advance.

 

Before you go into this have you tried replacing the fuse as I have seen blown fuses that look good to the eye but are in fact blown.

 

Definitely replace the "tail light" fuse and the "stop" fuse. Should be in the fuse box located by the driver's side kick panel.

 

I have the same problem. The tail light don't work but the 3rd brake light does work when I step on the brake. Weird thing is when lights are on at night bulb light up but when stepping on the brake they don't light up brither. Hopefully it make sense I need help since I have to take the car for light inspection.

 

Stop light is working fine. I'm missing a cover from a fuse box therefore I don't know which fuse is for tail light, but I removed and checked each fuse individually and all are looking good. I have a working stop light except outer bulbs (tail lights). Wiring diagram would help - I think I can track red wire to front panel and see where it gets a voltage from. Any additional info. would be greatly appreciated.
