Alfa 156 2005 HORN NOT WORKING
The two horns work fine if given current.
The fuse is intact.
When I remove the steering wheel airbag, there is current across the spring 'breakers'.
No current is reaching the horn wires.
I've seen the resolder advice for the steering-wheel circuit board but wonder, before you do this (and you wouldn't want to do it unnecessarily), could you not use a multimeter to test for a circuit from the two points on the board and, if you have one, presumably you don't need to solder that wire on. Or am I missing something?
This all seems to point to a faulty relay. My best guess is it's behind the dashboard fuses but I can't see how to get to it.
Any advice will be welcome as the car goes in for it's MOT in two weeks.
