Kind of hard to understand what you have done since you use no periods to form sentences..
YUP There are several trouble spots on Mopar dash clusters.
1 Is the cluster getting SOLID 12-14V from the ignition swtich on the power wire, traditionally dark blue
2 Is the socket arrangement for the voltage limiter making contact to the PC board?
3 Is the voltage limiter working?
4 Check or replace the nuts on the studs for the temp and fuel gauges, they get corroded and work loose.
5 Make sure the ground buss for the cluster is actually grounded. Usually, best way is attach an extra wire pigtail to the ground on the cluster, and bore a hole and bolt the other end to the column support
6 Make sure the pins of the PC board connector(s) are tight, repair, replace, resolder as necessary.
These gauges are a simple series circuit
The voltage limiter gets switched power on the "dark blue" IGN run line -- the limiter outputs about 5V to one side of BOTH gauges. The other terminal of the two gauges goes to each sender, one for temp, one for fuel.
DO YOU have a wiring diagram or shop manual?
