I received my cluster back and it still has issues, what's the problem?

Troubleshooting for Instrument Cluster/Speedometer

I received my instrument cluster back after repair and one of the following is happening:

• Faulty sensors may be the cause.
• If you only have an oil pressure issue (flickering or going haywire or turning completely off), most likely it is the oil pressure switch/sensor at fault. It’s a commonly known defect along with clusters in the year range.
• If you have incorrect fuel reading, be sure to check the fuel sender/sensor unit before sending it back in.

• All gauges are replaced with aftermarket high quality ones. If you are still having problems with the speedometer "speedo" or indirectly the tach gauge, it’s most likely the speedo sensor that has to be replaced.

• It’s most likely a wiring issue. Sometimes pulling on the wires instead of the tabs may sever connection to the cluster so we would recommend checking to make sure they are not pushed back. Electrical spray cleaner is recommended for clusters with power issues because corrosion settles on the metal pins. It is wise to spray both the pins and the plug itself and check for any bent pins. Lastly, make sure none of the fuses related to the dash and cluster are blown out.

• Check if the illumination background lights and check engine lights are on when hooked up. If the cluster is non-responsive but blocks appear all the way across the bottom digital display screen it’s an internal problem that has to be addressed at our facility

• This is most likely either a faulty harness plug, bad connection or fuse issue. Make sure the pins are not pushed back on the plug and the pins on the cluster aren’t bent. Clean both sides with electrical cleaner. Make sure there is no bad grounding.
