What caused tail lights to stop working? - 2003 Toyota Sequoia

Your front park lamps and rear tail lamps, use the same fuse and park lamp relay. So if the front park lamps work it's not the fuse or relay. The problem should be the wire circuit. The wire color for voltage at rear tail lamps is violet with white tracer. Use a test light and check for voltage, lamps turned on.
Your stop and turn work ok, correct?

loose wire or maybe a one thats ben cut , shorting out something

Hello. I know youprobably allready have the answer. I a just posting here for future use.


There is a relay to the left of the clutch on my 1996 Hilux. This was causing a similar problem for me. It is found on the left side, iside the car, left of the clutch pedal.

might have a wire shorting. did/do you have a trailer light hookup on it? a lot of times the connections dont get sealed properly and will short out especially when wet

in the rear lights you may have two bulbs one is the turn signal the other one is stop light / tail light the stop light / tail light has two filaments, one for the stop light (21 watt) & one for the tail light (5 watt) it is possible that the tail light filament is blown, try replacing the bulb to see if that fixes the problem,also check all the fuses as well.......hope this helps......cheers.

brake and tail lights do not work after changing bulbs, brake switch and the fuses are good

Hello. Definitely check the fuses, but also check the ground for the lights in the rear end as your symptoms could also be the result of a poor ground.

you could either have a front marker/signal lamp w/lamp grounded and causing this,remember...when tail lights are on so are your frt parking/marker lights on also..... other than that you could have a feed wire worn thru and grounding out to the frame

Check for faulty wires at the fuse block, had one fall off from the block itself from the rear, or it could be a wire break somewhere along the way.

Stop Lights and Blinkers are independant fuse.

Tail lights are on there own fuse and could be a wire break in the rear or removing the bulb and using a metre check for signal at bulb socket where trouble is, Check for disolored connections, Green in color or simular, could be a bad connection which in turn is not letting the curent to other side, Causing a short and loss of power to all remaining lights in curcuit.

Robynumber1,

Thanks for the email back. The nissan quest tail lights werenot operating, but the break lights were working. This was ultimately caused by a blown fuse. The fuse was blown by loose trailer lighting wires dragging on the ground, thus shorting. Problem fixed.
