Instrument cluster wiring 1989-1990 vw cabriolet

If the odometer on your 2003 Dodge Ram 2500 is not working, there are a few things that could be causing the issue. Some possible causes include:

1. Fuse: Check the fuse for the odometer. If it is blown, replace it with a new fuse of the same amperage.
2. Instrument cluster: The problem may be with the instrument cluster itself. If this is the case, you may need to have the cluster repaired or replaced.
3. Speed sensor: The odometer is connected to the speed sensor, which sends a signal to the instrument cluster to indicate the vehicle's speed. If the speed sensor is not working properly, the odometer may not function correctly.
4. Wiring: The wiring connecting the odometer to the rest of the vehicle's electrical system may be damaged or corroded. If this is the case, the wiring will need to be repaired or replaced.
5. Computer: The problem could be with the vehicle's computer. If the odometer is not working, there could be a malfunction in the computer that controls the odometer.

It's important to have a professional mechanic to diagnose the issue and confirm what the problem is before trying to fix it.
If you are not comfortable with troubleshooting the issue yourself, it's best to contact a Dodge Ram mechanic or dealership for further assistance.

This is one guy's advice: Replace the speedo head, that should take care of the problem."

This site is also interesting because the guy said
General Motors cars had instrument cluster problems from 2003 through 2006. When I researched instrument cluster problems on the Internet what I found raised concerns in me. Many of those vehicles had problems that began with the instrument cluster, but eventually led to the engine refusing to start.
(an electronic instrument cluster, digital instrument panel or digital dash for short, is a set of instrumentation, including the speedometer, that is displayed with a digital readout rather than with the traditional analog gauges. Many refer to it simply as a digital speedometer.)

I'd have to check voltage and ground for the instrument cluster. I noticed one of the fuses for your instrument cluster goes hot with the key on, same thing for ac compressor. I'd have to voltage feed to and from ignition switch for applicable fuse. Check the ignition switch wiring connector. I can't rule out ignition switch itself, at the moment.
There could be other issues?
Ignition switch faults are common on some makes and models.
Instrument cluster wiring connector problems. Sometimes if you disconnect and reconnect the instrument cluster connector, it may start working again, also, cycling the instrument cluster connector may reset, if it starts working, well, it's working for now, may quit again.
Some instrument clusters may do a self test, don't know about yours?
Press and hold odometer reset button, turn key to run position release odometer reset button, watch the odometer. Your indicator lamps may turn on and off, the gages may cycle in small increments. The cluster will exit self test on its own.
You may have to check buss circuits.

vw wreckers will have clusters that are in good condition

Your Instrument Cluster is controlled by the Fuse box under your dash. Do any of the other gauges work?

The GEM has nothing to do with it !
Odometer/Trip Odometer
The odometer and trip odometer are displayed in the integrated circuit LCD display. The instrument cluster records the total mileage of the vehicle using information received from the PCM, and electronically displays this information in the LCD. If this information is not received, the LCD displays all dashes. How did you prove that instrument cluster isn't bad ?
Did you have a factory scan tool hooked up , check for DTC'S - diagnostic trouble code's ? View data to the instrument cluster etc...
Instrument Cluster Diagnostic Trouble Code (DTC) Index DTC Description Source Action B1202 Fuel Sender Circuit Open Instrument cluster Go To Pinpoint Test B . B1204 Fuel Sender Circuit Short to Ground Instrument cluster Go To Pinpoint Test B . B1205 EIC Switch-1 Assembly Circuit Failure Instrument cluster INSTALL a new instrument cluster. REFER to Instrument Cluster in this section. TEST the system for normal operation. B1342 Instrument Cluster Is Defective Instrument cluster CLEAR the DTCs. REPEAT the self-test. If DTC B1342 is present, INSTALL a new instrument cluster. REFER to Instrument Cluster in this section. TEST the system for normal operation.

Your best bet ,take it to a qualified repair shop.

• The speedometer/odometer is inoperative

• Powertrain control module (PCM).
• Instrument cluster.

• Go To Pinpoint Test F .

Either you have a broken wire some where from the speed sensor to the cluster or you have connector at fault, the one which hookup the dash cluster to the main wire bundel. Check the connector, maybe a pushed back pin !!

My gas guage, speed odometer and tempiture does not work
The speed odometre is reading 9999999 what should i do

If the other dash lights are ok, you need to remove the instrument cluster and replace the bulbs on the back side of cluster....
