How to change the wipers on your 2008 Saturn Astra
1
Disconnect the old blade
Start with the driver's side. The blade on your Astra is attached to the wiper arm with a small pin that passes through a hole in the side of the blade. Hold the wiper arm in one hand and carefully pull the wiper directly out.
2
Set the blade aside
Once the blade is separate from the arm, place it to the side. You will see the pin that the blade attaches to.
3
Attach the included adapter
An adapter is included in the package with your wiper blade. Place this over the wiper attachment. It will hold the pin in place.
4
Position the new blade
Position the new blade so that the hole on the side of the wiper is directly in front of the pin on the wiper arm. Push the wiper on to the pin. You will hear a click when it is attached.
5
Done!
You're all finished with the driver's side. Repeat the process on the passenger side of your Astra.
