It wouldn't be a ground problem If it were the whole instrument cluster would be dead . Checking the BCM an the IPC for DTC'S - diagnostic trouble codes is the proper way to diagnose this type problem . Not worrying about grounds .
The vehicle odometer is calculated and stored electronically in the body control module (BCM) and is sent via the serial data circuit to the instrument panel cluster (IPC) for display. The BCM calculates and stores the mileage based on the vehicle speed serial data information from the PCM/ECM. The IPC displays the season odometer information from the BCM in the driver information center (DIC). The odometer will display error if the IPC detects an invalid odometer data from the BCM. After an invalid odometer data is received from the BCM, the IPC will display the last known odometer reading for 1.5 seconds before error is displayed in the DIC.
The instrument panel cluster (IPC) displays the vehicle speed based on serial data message from the body control module (BCM). The BCM receives vehicle speed data from the PCM/ECM via the serial data circuit. The speedometer will default to 0 km/h (0 mph) if:
• The PCM/ECM detects a malfunction in the vehicle speed sensor circuit.
• The BCM detects a loss of serial data communications with the PCM/ECM.
• The IPC detects a loss of serial data communications with the BCM.

Your best bet would be to take it to the dealer !

SOURCE: Speedometer Quit working, odometer also. Don't

What sounds like happened is that the instrument cluster fuse sounds like its burnt out. Otherwise the wires on the back of them both may have been knocked out. Very simple fix if its the fuse, if not, pull the cluster out and check the wiring. Hope this helps!

I own a 2007 chevy cobalt and the digital odometer went out. When I get into the car the odometer comes on for about 5 seconds but then quickly goes off. What is wrong with my odometer and how can I fix...

that is a dealer only part
the vehicle is picking up a fault in the unit and shutting it off this can
be caused by the installation of a aftermarket radio most vehicles
have an illumination wire that goes to the radio to dim the radios
display along with the backlighting for the gauges, the dimmer is somewhere around the headlight control. if this wire is grounding out
on the radio or anywhere else that could be the result.

Dashboard cluster is not lighting up

I assume you put an aftermarket radio in. Did you buy a wire harness made for your vehicle or just cut wires? A lot of cars these days use a bus system that has other wiring tied into it.

Before adding an aftermarket radio to modern cars, do a little homework into whether you need a special harness or not.
