Horn not working
Discussion
Hi Guys,
Just got my repaired steering control ecu back because my lights did not work properly. Lights work now. Horn does not work....
I got the steering wheel off. The horn button was not functioning, but this did not let the horn come back to life, We checked the signal at the steering control ecu (the purple/black wire) gives earth when I put a screwdriver between the 2 pins in the steering wheel boss. So, the signal through the steering wheel boss, the flat cables and out off the steering control ecu does work.
I saw in my hand book that the upper right relais on the fuse box is the horn relais.
Does the purple/black wire, coming out of the steering control unit, go to the relais? and does it then send out a 12V signal to the horn? The horn has a constant earth, so I guess this must be the case?
