Hello and thank you for your post. I am a master certified GM tech and can help you to resolve your issue. do you have a 12V test light or a volt ohm meter?
Yes I do
OK. You will need some pinpoint test ideas...first, go to the bulbs and test for 12V and ground at the headlamp bulb and tell me which is missing. Check them both. let me knwo and we will go from there.
I will be avail for about 20 more minutes, then on and off the rest of the day.
are you there?
OK i will switch out to q & A format.
I will have to do this later I am going to work .....
OK. get back when you know what is missing.
I need the 8Th digit in the vin ...a 1 or a K in case something is different
i await your response
Ok I have 13.8 volts at headlight and no continuity at ground.....8th digit of VIN is K
I also have no symptoms of bad BCM @ least I think...
Is there a headlight relay for lowbeams? could that be bad?
