If a fuse can't be removed, you can test it by measuring voltage on both sides of the fuse as referenced to the chassis of
the car, both sides should measure 12V.You can also measure voltage drop across the fuse. If it 12V, the fuse is broken.
It is also possible to place a 12V bulb over the fuse. If the bulb lights up, the fuse is bad.
Needless to say that the system voltage must be present in order to perform these tests
