Buick Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I'm an independent contractor here at Just Answer.
With your finger on the low beam relay does it click when the low beans are turned on?
Are fuses HDLO-BMR and HDLO-BMR good and powering up with the low beams on?
Thanks for asking your question and letting me try to help you.
If you are unable to rate my response GOOD or EXCELLENT now. Please let me know why ( if I need to help more) and when you will be able to.

YES IT CLICKS
Results on the fuses?
YES, ALL FUSES ARE GOOD! WE HAVE POWER ALL THEY WAY UP TO PLUG. WHEN I PLUG HEADLIGHT BACK UP THE RELAY CLICKS AND NO LIGHTS. IT DOES NOT BLOW FUSE
What is the voltage on these fuses headlights unplugged and while plugged up?
12 volt before headlight is plugged up
3 volts once you plug it up
Can you swap the low beam relay with another to see if the contacts are worn out?
Are the relay pins corroded or burnt?
If you remotely power these fuses do the low beams work?
not sure but I can check in the morning
Does this car have a headlight control module?
The dash integration module is the only module used on this circuit.
what does it look light and where is it located? Is that a common problem
Its a box shaped module about 1 inch thick above the passengers right foot and no its not a common part to fail
so................ have you ever ran into this b4 on a buick
This exact issue no, nor are there reports on it from other techs, but I can figure it out with your test results.
OK I'll check in the morning
I like to stay in contact with my customers that appear not pleased, still working on the concern, or have not rated yet. I assume you were not pleased with my help. I hate that you have spent money to get an answer but left not happy. Can you tell me why, or can I help more. If its more help you need just reply and we can pick up where we left off.
I didn't find it helpful because I had already tried everything you suggested, but I appreciate you trying. Thanks again! Still no low beams!
So are you just wanting to leave it as is. I hate that you paid money for help but are willing to leave with it unresolved when I am still here able to help.
What else is there to do? We've replaced the lighting module and all now! I even tried a new set of headlights! Seems as if it's a shortage of some kind
There is always something to do. You have a failure that needs fixing and there is a fix for it, but it is your decision if you want to fix it and want my help in doing so.
