This is not that difficult a task and can be easily done at home. Just follow the next few instructions and you will be able to successfully carry out your operation of installing wing mirrors on your Vauxhall Corsa.
Firstly, you will have to take off the door panel and then take off the inside mirror cover to get access to the bolts that grip the mirror on. Then remove each one of them and take the mirror off. Then you can replace the new one on to the door on the exact same place and replace the bolts. This job can become easy if you have a clip removal tool or a putty knife. Take the Philips screws from panel at the handle and pull. Then raise the handle out and pull off and then work around the panel to release the clips.
Then you can remove off the little triangular cover that wraps the mirror bolts. This is a very simple to do and you can easily do it at home.
For some more reference and the exact procedure on your Vauxhall Corsa you could purchase a Haynes manual for your car.
