2000 Camry LE 4 cyl

I have a mystery here. My tails lights (both) are out, the bulb is OK (checked) and the fuse is OK (checked) What could be wrong here. Turn signal lights and brake lights are OK

 

Do the rear side marker lights work, there on the same fuse?

Are any of the bulbs that don't work dual filament such as combo brake/tail bulb. If so, does the brake light filament still work in the bulb?

Is the bulb out icon on the dash light?

Use a voltmeter to check for power at the sockets. Make sure the ground wires to the socket has continuity with the chassis.

 

Do the rear side marker lights work, there on the same fuse? Yes they work fine.

Are any of the bulbs that don't work dual filament such as combo brake/tail bulb. If so, does the brake light filament still work in the bulb? Yes the dual filament bulbs are dead, both filaments, brake light and tail light. The bulb itself is OK I checked that.

Is the bulb out icon on the dash light? Yes that is on.

Use a voltmeter to check for power at the sockets. There is power at the quick disconnect that goes on the wires at the bulb end.


Make sure the ground wires to the socket has continuity with the chassis. Where is the ground wire(s) Perhaps that is the problem. I did not see any wire hooked on directly to the chassis

 

Does the high mounted brake light work, if so power to the brake lights at least as far is the brake sensor box.

Both bulb sockets share a common ground. The ground wires might be white/black stripe. There is a splice point at the rear of the car where the wires connect to each other. This would be below the license plate area and to the drivers side. Then a wire runs from there to chassis ground below license plate area.

Remove the rear trunk liner below the trunk lid opening and take a look.

Brake light power may be Green/Red. Taillights Green/Orange.

If you have an ohm meter check for continuity between the ground wire terminal inside the socket and ground.

When doing this determine if the socket connections have any corrosion on them that might cause a connection problem.

You can also splice into one of the ground wires coming from a socket and connect it to the chassis.
