The FSM says if you have a inoperative lamp to replace both the lamp and the lamp holder. Me, I'd replace the bulb and call it good as long as it worked...

CLUSTER BULB
This procedure applies to each of the incandescent
cluster illumination lamp and bulb holder units.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the instrument cluster from the instrument
panel. (Refer to 8 - ELECTRICAL/INSTRUMENT
CLUSTER - REMOVAL).
(3) Turn the bulb holder counterclockwise about
sixty degrees on the cluster electronic circuit board
(Fig. 5).
(4) Pull the bulb and bulb holder unit straight
back to remove it from the bulb mounting hole in the
cluster electronic circuit board.

And as the Brits say 'installation is the reverse of this procedure'
