when my head lights are on, my tail lights work fine. However, when i suppress the brakes, my left brake light turns on, but the right tail lights and brake light completely turn off. Is there a "string" i should be looking at to troubleshoot this?
Customer reply replied 2 years ago
I've checked the fuses, and all seem to be good. Ive checked the bulbs. They all look good as well.

  1. Can I get the year, make, and model?
  2. Is the 3rd brake light effected with this issue?
Ask Your Own Lexus Question
Customer reply replied 2 years ago
It's 1990 Lexus ES250. The 3rd brake light is not effected in this scenario. However, when my left brake light was loose, the 3rd brake light would be on even if my brakes were not suppressed.
Customer reply replied 2 years ago
Thanks for your help, Moose!
Customer reply replied 2 years ago
Oh... also, when my left brake light was loose, the tail lights were off (when they were supposed to be on).
Lexus Mechanic: Chris (aka - Moose), Technician replied 2 years ago

Sorry I do not work on cars that old. I will opt out and let another help.

Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

This sounds like a ground circuit fault to the right brake/tail light assembly or poor connection at this light assembly.I would start with checking the wiring and connections to the bulbs at the right side brake and tail light assembly to see if any issues are found.If any issues are found the fault will need corrected to resolve this here.If this is checked and all found to be o.k. let me know so we can continue from here.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete

Yeah... i already checked all the wires (including soldered wires), and all the connections are solid. The only one that i had previously found was due to a loose screw.
Lexus Mechanic: Pete, Technician replied 2 years ago

Did you trace the ground wires to make sure they are secure where they attach at including grounds from the battery to the engine block and body as well as from the lights themselves?
