recently my fridge stopped working completely,it seems to have no power,ive checked fuses they are ok...ive been told it might be something to do with the ignition control module as the van recently had a jet wash and water might have got in through the vent

Does anyone know where the ignition control module is and how i can access it,also if it is found to be faulty is it repairable or will i need to replace it??
Any suggestions are appreciated
