0000 Renault Clio indicators and central locking not working

My passenger window, electric sunroof and mirrors all work fine, as does the stereo and all lights apart from the indicators which failed suddenly along with the hazard warning lights, the drivers window and the central locking. Have checked all fuses and connections but still no joy. My next step is an auto electrician which is going to cost me loads so I thought I'd see if anybody on here could help me with any advice they may have . All suggestions greatly appreciated. Cheers
