Dash Lighting Question - Already Checked the Trunk Lights and wires

[Mark Pollan <Mark.POLLAN@mci.com>]

Hi All:

My dash lights are a bit flaky.  All the trunk wires are intact.  I
have to fiddle the light switch back and forth several times to get
the dash lights on and even then they may go back out.

Bad combination switch in need of cleaning?  How?  I squirted some
deoxit up there but no luck.

Other common failure points for this circuit?

TIA as always,
