MFA is fine; i use that quite alot no problems. My wipers all work fine. Its just when i did the washers which i havent used in quite a while. It was obviously some insulation on the wire burning away which ofcourse is worrying in itself! When i get chance i will take it apart and have a look. It was coming up from the hazard switch area.
Ill just keep clear of using the washers until i find out for sure, hopefully i should be getting my company car this week so ill get chance to dismantly it all.
