pull the fuse out and check the fuse male end with a ohmmeter and should have no resistance or should read 0

If all the fuses are ok then you could have melted a wire or blown a component that is why you disconnect the battery before doing electrical wiring

in order to diag you will need a voltmeter or a test light
