On the horn - first stop would be to check the connector and wires down by the horn . They're quite exposed to water spray and are known to often rot. Usual cure is to follow them back a bit to fresh copper and splice on replacement wires. Also verify that the horn itself is still working with some loose leads from the battery to the terminals on the horn.hi i got 2003 206 quick sillver 1.4 16v with some rather anoying probs i.e horn not working and dipped headlight on intermit when car running and lights are off which is cutting in on indercator i have changed squib and still have same problem![]()
