I found this on another site...

Noise From Passenger Side
of Dashboard: ’98–02 Accord
On ’98–02 Accords, if your customer complains of
hearing a ticking or creaking from the passenger
side of the dashboard, the hook-shaped
dashboard support bracket above the dashboard
support tube could be hitting the A-pillar. This
noise can be intermittent, temperature related, or
both.
To quiet this noise, remove the cover from the
passenger’s under-dash fuse/relay box, and look
up under the dashboard. If the support bracket is
hitting the A-pillar, use a long screwdriver
between the bracket and the body to bend the
bracket slightly so it clears the A-pillar.
This tip came to us from Andy Lee of Honda of
Serramonte in Colma, CA. Thanks, Andy.
