hi all this is going to sound like a stupid question but im trying to take my wiper arm assembly off i've got the wiper off but i can't seem to get the rest out i've undone the nut but what to i do now.
cheers chris

Yeh the assembly that connects to the motor

i think it goes in and comes out one way i took one out not to long ago but can't remember i half think there's a key??

19/20 remove from outside.
13/14 remove from inside.
 

Watch your paint when you remove 19/20.
Just take your time with it.
