How can i fix the auto light/rain sensors on my '05 Renault Clio?

I have an '05 Renault Clio and a few weeks ago the auto lights and auto rain sensors stopped working. I did see a post how to fix the automatic lights but i haven't tried it yet cause i don't have access to my car cause it's at home. I was wondering if the same sensors that power the automatic lights do the same for the automatic windscreen wipers? They both stopped working at the same time which is the reason i ask. Is there anyway of fixing either?
Thanks
