yes, there is a fuse for it. your owners manual should tell which one.
if you don't have an owner's manual, try checking each fuse
individually. you can do this with a visual inspection, a test light,
or voltmeter.
however, your more likely problem could be that you're low on "freon"
which should take 134a.
and of course, there's always the possibility of mechanical failure
somewhere in your a/c system.
