What to check next
Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Before buying a cluster, have a technician compare available engine-speed and vehicle-speed scan data with the failed gauges, using equipment that supports the relevant systems. No codes on one reader does not establish that the cluster is faulty. Check the cluster's power, grounds and connectors using the wiring diagram. If the required inputs reach the cluster correctly while its gauges fail, cluster repair or replacement becomes a stronger option. If speed information is missing upstream, investigate that signal path first. Confirm part-number compatibility and any setup or odometer requirements before fitting a used unit. Avoid driving with unreliable speed indication. Comparing the incoming information with the gauge response helps separate a cluster fault from a supply or signal problem.
Guidance references and applicability
Fluke: Diagnosing voltage drops https://www.fluke.com/en/learn/blog/automotive/electrical-automotive-troubleshooting General support for checking supply and ground integrity under load. Scan-data comparison is a proposed diagnostic approach; this reference does not supply Stratus cluster pinouts or certify scanner coverage.
This can be the instrument cluster going out, or the ignition system is having issues which will affect the tach, also you may have a VSS going out which will make the speedometer not to work, we need to run the codes first to see which way to go for the repairs. please go over this video.

I am not seeing any trouble codes.My code reader is an Innova 3100J and may not show all codes.

Okay, chances are the cluster has gone out, I would see you if can get a used unit from Ebay and install it.

Discussion summary
Instrument Cluster erratic tachometer and now speedometer is not working?
The owner of a 1998 Stratus reported an erratic tachometer followed by a nonworking speedometer. Their Innova 3100J showed no trouble codes, although the owner questioned its coverage. A contributor suggested a replacement instrument cluster. No replacement or repair result was reported.
Reported outcome: The owner acknowledged the suggestion, but no diagnosed cluster fault or successful replacement was reported.
No cluster-input measurements or enhanced scan results were supplied. Lack of reported trouble codes does not establish the cause.
