Have a 84' GL with some type of low beam head light issue. Had a low beam light go out on me, so I installed a new one, but it still did not come on. When I tried the high beams, all 4 lights (including the new low beam one that wasn't functioning on low) came on.
I checked the connection and the low beam stock number to make sure I didn't buy a high beam one by mistake. Both checked out.
I assume it is electrical, but really don't know.
Any thoughts, suggestions, troubleshooting ideas, would be appreciated.
