The horn beeps when I strain on the steering wheel to turn it when the vans stationary. Ok when moving as it's takes less force. Just what you need when you busting a blood vessel try to narrow park and you've fitted an air horn. Popped the horn out and the central contact ring is positioned centrally, so not visibly earthing the sides. I can move the steering wheel up down side to side about 3mm, is this typical?
