Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I'm Ron and I can help you. This is not a short, but either a bad ground in the circuit or a bad connection at one of the headlight connectors. I would start with disconnecting the connectors one at a time, cleaning them and applying a di-electric grease to all the terminals. You can get this at a parts store. This will most likely cure your problem. Hope this has helped you. please let me know, and I will still assist you after you have rated me.
