How to install wiper blades by yourself?
In general, installation is an easy job for many cars. I can even install it with one hand. There are many videos on YouTube on how to install it. You may check and learn from it if you are not sure about it.
On packaging, normally there all drawings showing how the installation should be carried out by different connectors.
If you are really not so handy, you may need a company providing installation service. But due to cost concern, it could be hard to find such a company.
