Trying to get the leaf guard off my combo van and am stuck on the wiper arms....I undid the bolts, but they won't budge....any suggestions?

 

with the nuts removed like you have done ,spring the arms fully away from the screen and give the arm a tap with you hand or something,this should help .holding the arm with the other hand .just a small tap should do mate ,

 

okay i did all that and they're still not budging. I cannot see any pins keeping it in place, but the whole unit moves when you try to get them off...
