2007 es350-day light running
Hello,
My name is Asanta and I am a new member to the Club Lexus. I have a 2007 ES350 Ultra premium with mileage of 211K. Very recently Driver side daylight running light and high beam light stop working.
I tried to change the bulb but not working. I took the car to Lexus Dealer they checked and said there is power but No Amperage. They need 2/3hrs to start diagnosis the problem. I never had any problem with this car or lights. I would appreciate any input suggestion for this issue. My nights lights are working.

the wiring diagram shows a DRL relay, maybe thats the fault, but
HINT:
z The power distributor has a fail-safe function control. If a short circuit occurs between the power distributor and high beam headlight bulb, the power distributor stops the DRL relay operation.
z The DRL relay is built into the power distributor, so unlike conventional relays, it cannot be removed for inspection.
z If only a high beam headlight on one side does not illuminate, inspect the fuse, bulb, or wire harness that is related to the bulb.
z If both right and left high beam headlights do not illuminate, read the dimmer switch HIGH signal value in the data list, and perform the DRL relay active test to determine if the malfunction exists on either the switch side or the relay side.

2007 es350 dlr
Hello Nevernu,
Thank you for your post and diagrams.
In my ES350 Only Driver side Daylight and High beam lights are not working.
When I turn on the night light (HID) is working on both side. I have checked the fuse and wiring harness seem to be fine. Also replaced with new bulb.
Lexus Dealer looked into this and unable to find a solution and asked to bring the car for diagnoses (2/3 hrs charge) and not sure what is the problem. I am a bit disappointed because the dealer is not sure,,
Don't the dealer have specific test to find the problem? Why didn't they check DLR relay ? Dealer already spent about an hour time when I had the car for other service.

Any prior front end body repair? Since you are in Ontario, salt zone, I would also check the wire harness ground bolts in that area for corrosion and, if it was in accident, for poor repair of the grounds...
