Hi Sunstatepilot,
Unless you are very handly with tracing electrical faults you're pretty much stuck with taking your car to a service shop as you could be at risk of an electrical fire. There are a variety of possible causes for the burnt wiring and you fuses will not always blow unless the current exceeds the amperage of the circuit they protect. Wiring will still be prone to burning up even if the current does not go over 15 amps if you have a ground fault, (short circuit).
You need to find the point at which your wiring is grounding out which can involve removal of your Climate Control console, your glove box, knee bolster,
etc. Depending on your luck and skill removal of the above can take @ 2 - 3 hours.
Good luck.
