Guages and insturment panel stopped working on a 1998 plymouth

In the event that you have not completely fixed this problem, I suggest the following: Do a google search for "98 voyager instrument cluster solder" and you will find an abundance of posts regarding the soldered joints on the main terminal connector on the back of your instrument cluster. If the behaviour is at all erratic and unpredictable, or hitting the dash makes the gauges come back to life, then you are about 99.9% sure it is the solder problem. It takes about 8 minutes to remove the instrument cluster (okay maybe 15), and about 2 minutes to remove the circuit board. By examining the solder joints of the main connector with a magnifying glass, you will probably see cracked or corroded solder on them. Briefly reheat each solder joint with a soldering iron to re-flow the solder. Your erratic gauge behaviour should now be history.

Yes you have to change the body control modual it is under the dash and usualy is white and most likely you will have to reprogram at the dealer once replaced. But the body control mod controls all those items and they like going bad.
