Ok I pulled into my parking spot and either my A/C compressor or Alternator just let go. It sounded funny and then must have frozen. Because when I tried to turn it over it was VERY slow turning and almost didn't have enough to start. Definitely something frozen.

So how do I remove the belt? I want to remove and figure out which one is frozen.

Thanks in advance.
