Car horn only works on one side....?Is ther a contact that could be dicky?Also stop/tail bulb blue......Halfords said replacement bulb was standard 380,but thats not true.380 is 21/5 and bulb i replaced it with was 566 21/4 off pin set.My cars is imported..Surely all octys are the same.

octy has two horns that work independantly depending on which side you push down push both sides down and you get a louder horn soudn (if both are working that is)

it coudl be a connection or mabe it just needs a clean or one horn unit replacing...

To access your horn (ooer missus) you need to take off your front bumper they are located at the passenger side behind the blocked up grill.

What id would do to determin if it was the connection is swop the wires over and see if the noise swops over when you push on the steering wheel.

Need any tips on how to take off the bumper? there are a few tricks and hidden screws...
