I just bought some new wiper blades, and I tried to put them on, but I dont know how to remove the old ones from my car..

the ones on my car are the original ones and it looks like its attached by a hook,

how do I remove the blades?

 

anyone?

 

well after lifting the wiper arm up and having the wiperblade facing up towards the sky, there should be a button (not sure for the original) and you push on it while pulling om other side of the blade towards the ground and out it comes

 

i was able to get the original blade off, but I got the Rain-X wiper blades, and when i try to put it on, I am able to put it on, but it does not snap on like the original. When I pull down on it, it comes off again, is that normal for the Rain-X ones,?
