Today I tried to take off the wiper arm on my b5 a4,loosened the nuts off and it seems the arms are seized right onto the pin,Is this a dumb question or is there a trick to this I tried to free them but nothing.Any sugg.?

 

You have to rock the wiper towards the windshield and away. Eventually it should loosen and come off. You can also use a battery terminal puller to get them off.
