Rear window washer jet

[Ian...]

Hi all, I've have a Honda CRV 2010 and my rear window washer jet is blocked. I've followed the advice of you on this matter by reading up on others that have had the same problems and the suggestions that's been offered. I know the route of the pipes via a picture one of you posted so many thanks however I don't know how to remove the inside plastic panels to get to the pipe or how to take off the inner wheel arches without damaging the clips. Will the Haynes manual auto fix show me how?? I don't want to buy it and find it doesn't help, can any of you good  people please let me know
