Question about 2007 Lexus GS 350 AWD Sedan

Open Question

My front left headlight comes on, stays on and then turns off. Sometimes the left does the same. Rarely, they both turn off. The bulbs are fine as I had those checked. Is it the relay switch possibly? Can the relay switch be easily replaced or is that a job for a tech?

SOURCE: turn signals

Carefully look at each bulb you replaced. You will find that you have replaced a double contact bulb with a single contact bulb or vise versa.

SOURCE: no power to left front headlamp - low beam

There are relays that control the headlights in a fuse box under the hood near the firewall.. There's also a fuse box underneath the dash on the driver's side, but can't remember if it's on the underside of the dash or beside it

Right front side turn signal does not work replaced all bulbs and checked fuses headlight flashers work when hazards are on front to back except driverside turn signal ,in dash right stays solid left


I don't believe it would be a bad ground for just one light. It could be a wire, a socket connector, or the bulb socket itself. See if the wire has power at the socket when signaling left, with key on. If there is power, probably a bad socket or connector. If no power, check for power coming from flasher-the wire going to front left, or driver's side. If you have power from the flasher, but nothing at the socket, the wire has probably broken.
Good luck.

My left headlight is out. replaced it twice. High beam works with both bulbs. My tail lights come on but left one doesn't blink when left turn signal is turn on. Front turn signal works fine


Sounds like you have a bad left rear light bulb, as far as the Left Front headlight i would check to make sure you have power and grounds at the connector, if you dont trace the wiring down and check fuses , the grounds should be close to the source.

I have a chevy s10 2002,the headlights do not turn on, the high beam works fine, bulbs are fine. thanks for help


If it's not the bulbs, be sure to check them, might be dual filament and the high beam wire is fine but the headlight one is shot, one bad wire would cause both headlights not to work.
Hopefully that's the problem, if not, it could be blown fuse/short in the wire. Try checking power/ground at the bulb to reduce the possible problems. If it has both with the headlights "on" then it's the bulb, if it's missing one then follow the wire for any irregularities.
They sometimes pass the wires under the flooring right near the drivers feet, which is a perfect place for water/salt to seep in and corrode wires.

Driver side signals only work when headlights are OFF


What may have happened is either the headlights wiring or the parking lights wiring somewhere along the wiring fused to the left turn signals wiring. Depending on if the turn signals go on when you put the parking lights on or the headlights on.

If the signals come on when you turn on the headlights than you only need to locate the light green wire that comes off the left turn signal harness.

Next follow that wire the entire way back to the firewall looking for another wire fused to that wire as you go.

If there are no signs of this you need to continue looking on the other side of the firewall all the way back to the turn signal and hazard flasher unit which is a black box that connects to a black harness located next to a grey harness behind the knee bolster.

But if the signals come on when you turn on the parking lights than you will also need to check the wiring from the rear left signal and follow that light green wire all the way back to the turn signal and hazard flasher unit.

This should fix your problem, but if not than your problem may lay within the the wiring between the turn signal/hazard switches and the turn signal and hazard flasher unit.

Also you may have a burnt circuit in the junction block. This block is where the light green from the rear left signal and front left signal meet. Don't have a description but if you cannot find it let me know and I will go out to the yard and look myself and let you know.

Electrical problem


Find the ground wire on one of the lights and add another ground wire to a good clean metal surface and see if that fixes the problem. It defently sounds like a ground problem at one of the lights.
