Gauge Fuse - Blown
Number 84-8-4 Date 12/83Subject: BLOWN GAUGE FUSE - FIERO
A condition may occur from repeated deck lid release operation on Fieros which could cause the 10 amp gauge fuse to blow. Loss of this circuit will also affect operation of the voltmeter, tach, TCC, cruise control, rear window defogger and "Lights On" chime.
To repair the above condition, the amperage rating of this fuse has been changed to 20 amps. Should you experience a blown gauge fuse and no evidence of a short or ground is apparent, install a 20 amp fuse in the Number 8 terminal of the fuse block.
