I am not sure if there are any other fuses, but if somebody can find you a wiring diagram you could test the compressors wiring connector for voltage.
Do you have a multimeter?
I have heard of these compressors having problems where they will run constantly, and this can cause them to burn up.
It is costly to replace the compressor, you are better off replacing the struts with Gas Struts, they have conversion kits.
If the struts are still in good shape you should be able to get a manual fill kit, I cannot find a link to the kit at the moment, but I am sure Justin will post a link to the kit when he sees this thread.
I think it is Monroe AK29, AK29 being the part number, wait for conformation from him before trying to buy this kit, let me see if I can find the link to a thread he has about the kit.
I am not able to find the link to the thread I mentioned, I am sure he'll respond ASAP and be able to assist you.
