If all fuses are good, it probably comes from the wiring harness. You will need to find a wiring diagram for your car and start from there or check all connections from the battery to the fuse box. A multi meter would also be easier to use than a light

You need resistance readings as well as amps/volts readings so a multi-meter is what you need to check that wiring harness.  I have used my wiring diagram that I bought several years ago more than I care to remember.  Those two tools are absolutely necessary if you are going to repair your own car.
