I have a 96 impala ss, my problem is that the passenger side headlight is dim. I replaced the bulb twice and got the same results. The wires aren't burnt and the fuse is good. The driver side head light shines fine, just need a lil help on this thanks
You might have some corrosion on the connector pins/sockets. Check the voltage, and if you can current draw. Feel the connector for heat (resistance causes heat). Make sure the ground for the light is good.
Near the passenger side of the radiator, on the back side of the core support, is the ground. I'm betting it is corroded. Undo the ground screw (10mm I think), and clean it all up, to include the contact area of the core support, and reassemble.
