My name is ***** ***** I am a licenced diagnostic technician with over 20 years experience.
I will do my best to help you with your automotive problem. Please remember, I cannot see, hear or feel your vehicle which can make diagnosing very complicated and some vehicle require extensive diagnotics that require certain diagnostics computers that can not be done over a computer or phone.Please be patient as I am not online 24 hours a day, as I do work, but I do check my page every day.A positive rating is always appreciated for my time and knowledge to help you with your problem.
I am going to include a wiring diagram for the heaadlight circuit for you as this is going to require a bit more hands on testing, but you are 1/2 way there and checked some important areas already.
If you have 12v at the left and right headlight fuses when switch is turned on than that means that the headlight relay is working as it should. The headlight relay is ground controlled from the drl module, biut if you have 12v at the 2 fuses than imassuming that the ground signal at the red/white wire before relay is there.
Do you have 12v at the headlight connectors? if you do than it is the ground controlled portion we have to target.
the switch is entirely ground controlled. there should be ground at red wire pin 12 when switch turned on than it goes through a junction block before the drl module red wire pin 5.
If all of this is fine than than there should be ground signal coming out of drl module pin A red/white wire.
check drl module grounds and 12v supply. IF all this checks ok, it will be the drl modue (which i hve replaced a few)
IF one is missing that you will have to check the wiring between each.
IF you need any more help, let me know!
I appreciate positive ratings!
