my headlights aren't working properly. I have a 1990 honda civic DX, and the lamps were cracked when I bought the car. no problem, just replaced them. I assumed that was the problem. but the low beams still don't work, and the high beams emit a very dim/weak beam of light. I've checked the fuses as well. Could it be the wiring? or something else? any idea how to fix something like this? I would rather not go to a mechanic and have to pay 50-100 bucks for something that could be an easy fix.
