Okay.. so i have a 1993 Nissan Quest that the high side on the bulbs keep getting to where they dont work.. to make it more specific i have having headlight problems and when i turn the bright lights on.....
You really need to verify a good clean ground for each headlight - it is possible you have corrosion either on the end connections or in the middle of the wire. It may be a good idea to just replace each ground wire for the respective light. Splice into the existing ground and run it to a new location, ensuring there is no paint or rust in your connection and putting dielectric greaseon the wire end,terminal, and underside of the head of your fastener. The cut the old wire so that fault cannot cause issues with your new ground. Don't wrap your new wire around a bolt - use the proper gauge eyelet terminal. If you use a pre - existing ground ( like on the alternator bracket ) wire brush the bolt head underside and mounting area clean along with whatever eyelet terminal there, grease all sides using fresh dielectric grease and tighten bolt securely.
This should cure your problem - if not, then test ( and replace if necessary ) whatever headlight relay (s ) you have - they may overheat and short out, causing a power surge that would blow the bulb.
