280ZX Headlight Problems

A common problems on 280zx's is one (or both) headlights getting dim. The usual culprit is the backside of the combination switch where the lights harness plugs in. The 280zx (S130)combination switch has a common faulty pin due to electrical overload. The pin heats up and gets carbon buildup. This buildup causes a dim lamp or complete failure at the lamp as the carbon causes resistance in the circuit.

Below is an image of one of these switches that has the
buildup.
