Renault Megane windscreen washers and aircon not working?

Hi guys, thanks for all the information posted here but unfortunately it didnt solve my problem. I drive a 55 plate 1.9 dCi 120 Dynamique with similar problems. The cigarette lighter and radio works - no problem. However, the windscreen washers and aircon do not. I have checked all the fuses under the bonnet and glove box and all seem to be good. Any advise will be appreciated. Thanks Dee
