Hi everyone this is my first post so hope you can help. I have just realigned the rear door on my Picasso which worked but when I tried to retighten the bolts one on each hinge won't retighten does this mean the captive nut on the other side has come away,and if it has how do I fix it. Geovil

Can anyone tell me or show me any diagrams of where the Car Horn is located and what has to be removed to get at it my Horn sounds very ill and needs fixing or replacing,I have replaced car horns on other cars and also found that sometimes all they need is readjusting is this possible with this horn it is the horn that came with the car. Any help would be most appreciated Geovil
