Okay, well, I searched for this and got nothing, so here goes!

I got in an accident recently, and since then my passenger headlight and my running light doesn't work, except for when I signal.

Also, my speakers suddenly don't work since then either!

I've checked the 5 amp and the audio fuse, and they're both good. Any insight on this?

More than likely, there was damage to the wiring for your pass headlight and running light. I would pull the whole pop up assembly out and check the harness for the headlight and marker light. More than likely, the harness got sliced/disconnected shutting the headlight and marker circuits down. The combo lamp (as the marker/running light is called) has two power wires and one common ground. One power wire (Red/blue) is for the running light (dim) and the other wire, which I can't remember the color of hand, is for the turning signal (brighter).

Normally I'd say it's a ground, but your turn signal still works, leading me to believe it's a power supply issue.

As for the speakers, you got me on that one. A frontal impact shouldn't damage the audio wiring, unless you were running some monster cable for an amp.

Also, If you're any good with wiring diagrams, make yourself friendly with the EL section of the service manualhttp://www.240edge.com/manuals/91-94_240sx/el.pdf

In particular you'll want the "Power Supply Routing" page and the "Audio" page. If all the associated electronics are down that are fused along with the radio, you can bet it's an issue with power routing. Nissan runs the power line from the battery to the passenger fusebox, then around the front of the car into the driver side kick panel where it goes to the key cylinder to branch into ACC ON START. The Blue (L) wire is routed from there to the indoor fuse box and then on its merry way to its final destinations.

I doubt that would be the case though because I assume your car starts.

It kind of starts, my alternator doesn't hold a charge at ALL, so until tomorrow when I get it re-brushed and all that I have to gimp it! Also, in the crash my electric fan got destroyed, so I unplugged it and took it out. I'll check out all the wiring tomorrow. Thanks!

Okay, well.. I put in a new Alternator and battery, which fixed my headlight problem. I turned on my stereo and it actually worked! for about 5 minutes, then it went back to the popping sound when I turn it on.

And today, when I started my car, most of my interior lights went out, except the clock (until I turn my headlights on) and the little one in the ashtray. Anyone have any idea what's going on?
