Windscreen wipers

Can you swap the wiper blade around so that the larger wiper does the drivers side?

I am sick of only getting a small bit wiped away. Plus you get the overlap mark right in the middle of your vision.

Can anyone give me detailed instructions on how to do this?

thanks

sorry this is common to 307 everyone moans about it, i have heard that some ppl losen the o/s wiper and raise it this helps a bit but then it parks to high, the problem is the french are all left hookers (left hand drive)
