How to remove wiper arm
 

Hi,
Some a²ç&*ole broke my rear wiper arm.
I bought a new one but I can't seem to be able to remove the old one.
I removed the nut that holds it but I can't pull it out.
Is there any trick to it?

Thanks,

Its on a spline and is probably rusted a bit. Just keep wiggling a pull, it will come off.

It's not rusted as the car is 4 months old and despite pulling hard enough it won't come out :confused:

Keep going, it will come off.
