I was able to get the nut off but the arm would not move. Haynes has nothing on wiper arm removal. Thanks

 

Yes, someone please help us. I would like to know too.

 

The blade or the whole wiper arm??

 

The arms are pressed tight to the motor spindle. It requires a puller and a lot of force, and is a difficult deal. GM has a special puller just for this.

I took mine to the dealer, and I usually would do this myself.

 

Thanks, I'll give that a try.
