Hi,
My car is a Nissan Sunny, circa 1993. When I turn the headlights on, I
hear a noise that sounds rather like radio interference (even thouigh
the radio is turned off) - a sort of irregular rasping buzzing sound.
Anyone advise what that might be, and the remedy? I sounds like it is
coming from somewhere to the right of the steering wheel.

Could be a dicky relay.

When I was having the brake pads changed yesterday, I asked my local
mechanic to listen to the noise. He confirmed that it was the relay
making the noise. He said the relay was making the noise because there
was bad continuity in the circuit feeding the headlight somehwere.
However, he was unable to find the exact location of the fault. He
tried removing and replacing the headlight bulb and a couple of fuses,
and fiddled with some earth connections but to no avail.

He also pointed out that one of the headlights is not coming on
properly.

Anyone suggest how I can trace the problem?

Thank you.

Have you actually tried a new relay. Dry joints on the relay base are not
unusual, I have resoldered a few successfully. Don't forget you have two
circuits to check, the high current circuit through the relay to the light
and a low current switching circuit to the relay.
