I have a 2003 Prando Grande that has been buzzing intermittently for a couple of years now but recently seems to have got more consistent - I also thought it might be a defective relay. Have just looked on this forum for the first time and wonder if any of the above have eliminated the noise.

There is an intermittent buzz within the dashboard that sounds to me like a faulty relay. I think is linked to the suspension. Can anyone advise - I live in the country so just popping around to old mate is not easy.
