I gave my wiper arm a light tap with a rubber mallet around where the nut came off. Mine was solid and wouldnt pry off at all. After a couple of taps it just popped off Just dont put your window thru
Kango hammer time.
got the wiper off by unscrewing the motor and hammering on the nozzle and pulling the wiper arm so scared of slipping and doing my window in!!used auto glym super resin polish and still looks the same
