Start by identifying your vehicle to include year, model, engine, and transmission.
Have you checked fuses that are listed in owner's manual? No owner's manual and 96 or newer? See below.

start by checkin all the basics which includes batt voltage, batt connections, and fuses. and CHECK FUSES WITH A TEST LIGHT. just because a fuse 'looks' good does not mean it is not bad.
