WARNING: This page is about a different car, the 1994 Plymouth Acclaim, 1994 Dodge Spirit, and 1994 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: When a problem occurs with any gauge, before disassembling cluster to test gauge(s), check for loose connections or faulty wiring.

If fuel, voltage and tachometer gauges appear to be malfunctioning, remove the cluster assembly. Check for good pin contact between wiring harness and printed circuit board. If there is good contact, check for ignition voltage at Black connector cavity "C". See Figure -Figure . If there is ignition voltage, check for continuity between wiring harness Black connector cavity "H" and ground. If there is continuity, replace printed circuit board.

If temperature, oil pressure and speedometer gauges appear to be malfunctioning, remove cluster assembly. Check for good contact between wiring harness and printed circuit board. If there is good contact, check for ignition voltage at Red connector cavity "J". If there is voltage, check for continuity at Black connector cavity "H". If there is continuity, replace printed circuit board.
