On the '''1984 Digital Clusters''', a common failure is the '''Fuel Gauge''' section dimming over time and eventually going completely dark. This can also occur with the
'''Coolant/Oil Pressure/Voltmeter''' section either individually or together with the fuel section.

The root cause is '''failed electrolytic capacitors''' on the cluster’s main board. When these capacitors fail, they leak electrolyte that corrodes the copper traces and surrounding
components, leading to permanent damage if left untreated.

In severe cases, the electrolyte seeps under '''transistors, Zener diodes,''' and even '''brightness control potentiometers'''. This can require extensive repair or complete
replacement of the board.

If caught early, some damage can be cleaned and the failed components replaced. For minor board trace damage,
'''bridging the broken traces''' can restore functionality. However, if corrosion spreads too far, the
cluster may suffer '''complete failure'''.
