I have a real odd issue. When say el. windows is used or clima switched on I get sometimes a message that 'self leveling system' does not work. The odd bit is rear and front window wipers start moving slowly at the same moment! I have contribute this to front fues box because all 3 relays are in there. Something like supply to box is not stable perhaps?





Has anyone seen anyting like this before? Any advice welcomed.




Thanks
