Horn problem. - ZR-1 Net Registry Forums

Hi guys! I have a problem with the horn. When you push the buttons while you are driving, horn does not work. But, when you stop the car and you take off the key and lock the steering wheel, the horn works perfectly with buttons.

Because of that, I understand that buttons are working well and horn relay too. Even so, I check with TECH1 the horn relay and it's perfect. I can play horn with TECH1 directly.

I think that the problem is in the spring that secure contact between wires from buttons to SIR Coil.

Any advice to check the steering wheel connections? Anybody with the same problem? I want to check it next weekend...

Thanks in advance!!
