CAN YOU USE FUSES THAT AREN'T VOLKSWAGEN?

What is your question?

wHAT ARE THE FUSES THAT SETS RIGHT ON TOP OF THE BATTERY?WE ARE TRYING TO GET OUR BUG READY FOR MY DAUGHTER TO GO OFF TO COLLEGE AND SO I AM TRYING TO FIX IT OURSELVES. APPRECIATE ALL THE HELP THE AIR CONDITIONER BLOWS BUT NOT COLD SO WHEN WE GASED IT BUT STILL DOESN'T WORK COULD IT BE THE REASON THE FANS DON'T WORK
