How to Troubleshoot a Chevy HHR Gauge Problemby Daniel Valladares
Problems with the gauges on the instrument panel of your Chevrolet HHR truck can be caused by three issues: a faulty fuse, loose electrical wiring or a malfunctioning instrument panel. If the fuse is the issue, replace it to solve the problem. Repairing loose electrical wiring usually means that you simply have to reconnect the them. If your instrument panel is malfunctioning, you will need to buy a new one and install it into your truck.
Open the hood, locate the fuse box and open its lid.
Locate the "Cruise" fuse, which protects the cruise control and instrument panel. Remove the fuse with a fuse extractor tool.
Install a replacement 10-amp fuse into the "Cruise" slot, close the fuse box and close the hood.
Gauge Wiring and Gauge Replacement
Open the hood and disconnect the battery with a socket wrench. Remove the three clips holding the dash panel above the instrument panel using a flat-head screwdriver. Pull off the dash panel.
Remove the four screws from the instrument panel. Reach behind the panel and locate the two electrical wires. Make sure both of these are securely connected to the instrument panel. Connect them if necessary.
Reconnect the battery and test the gauges. If they are still malfunctioning, you will need to replace the instrument panel. Disconnect the battery. Disconnect the two instrument panel wires and remove the instrument panel from the dashboard.
Install a replacement instrument panel into the dashboard and connect the two wires. Install the four screws and reattach the dash panel and its clips. Reconnect the battery and close the hood.
