I'm experiencing an oil leak coming from the backup light switch (gearbox, passenger side). I've tight it better to check if it would have solved the problem, bu if it's gone i need to change it, so i'm getting prepped to find one... and it doesn't seem so easy (even to the mazda dealer).
Do you gave a good source? Preferrably in Europe... but wourldwide would works as well.
Thanks!
