Default Nissan Sunny electrical fault

My daughter has a 1989 Nissan Sunny 1.6 GS. It has developed an
electrical fault, whereby when the headlights are dipped, the nearside
headlight does not light, and there is a regular clicking sound from the
engine compartment.

Headlight bulb has been replaced, but still the same symptoms.

Relay box has been replaced, but still the same symptoms.

Nearside full beam and offside dipped/full beam work OK.

Ideas anyone?

You may have a Dim-dip unit that basically switches the dip beams on half
volts by putting the headlight earth in series.This happens when you select
sidelights when the ignition is on and when you switch to dip the unit
switches the earth back to parallel.

Indeed the OP's car may have dim-dip, but how does that relate to his query
about the N/S dip not working?

Because if the dim dip relay has failed then then it won't work

Yep, *I* understand that, I'm an electrical technician, but the OP wouldn't
have.
