Fuse 18 in the passenger compartment is only hot in RUN. Are you testing with the key on?

As previously stated this fuse is hot in ON !!...you may have to get inside the fusebox and see if you have power on pin A7 on the C2 connector...your 97 matches up with my ‘01 connector and pin location.

Sorry to hear that but there are quite a few on this Forum that are good with electrical !!...there are only a few basic types of automotive circuits...potensiometers, thermistors, solenoids and once you understand how they function electrically it’s easy and can be applied to all cars !!
