2000 Mitsubishi Galant Q&A
2000 Mitsubishi Galant Question: passenger side brake light keeps going out.
If it goes out it's an 'open' if it blows a fuse or burns wires it's a short (very general) you can have ground-to-ground shorts in ground controled circuits but they generally cause feedback and wacky problems not described here.If the light comes on simply by lightly tapping the housing the filament is most likely broken and when you 'mess' with it the filament makes contact and works , as you've noticed , temporarily.If this sounds like what you've got first thing is to put a known good bulb(poss. brake bulb from drivers side) if symptom switches sides you know it's the bulb.If not start checking the wiring harness especially where it runs along the hinge pull back or unwrap any neccessary to make sure no broken but barely touching wires. - ziptie12
