Frequently Asked Questions

Most repairs are done the same business day they are received, but always within 24 hours. Orders are shipped back within 24 hours upon receipt.

We return all units via USPS Priority mail or UPS Ground and we email you the tracking number once the order has been shipped. Overnight and express service is available upon request, please contact us for pricing or leave a request on the service form.

No. We rebuild your original cluster and it is returned with the same mileage. No programming or flashing is necessary.

Yes your vehicle is drivable without a cluster but you must understand doing so at your own risk. Using a GPS unit such as Garmin or TomTom will provide you with a speedometer and odometer (for fuel gauge reference).

For instrument clusters we repair and upgrade all gauges to new OEM fail-free gauge motor mechanism (stepper motors), backlighting bulbs, shift indicator (prnd..) display, internal power supply, and other electronic circuit and component issues, (issues like: that may cause Instrument cluster to drain the battery when vehicle is turned off etc) and more. We fully test entire instrument cluster after repair and calibrate all gauges.

We specialize only in GM Instrument Clusters ( Chevrolet, GMC, Hummer and Cadillac )
We are one of the first original GM Instrument Cluster Repair companies in the USA
Over 15 years in experience.

100% Guaranteed or your money back!
​Not only do we repair gauges, PRNDL shift indicator display and backlighting in the GM clusters, but we also repair battery drainage issues caused by the cluster, power issues and do preventive maintenance upgrade so the cluster won’t have any issues in the future.

And you prepay for the return shipping back to you from us when you submit an order and check out.

We provide a lifetime warranty on all Instrument clusters’ gauges (stepper motors), 2 year warranty on backlighting. We cannot provide warranty on other issues that your vehicle or cluster might have.

Repaired my GM 2500hd gauge cluster. Backlighting and needles work excellent now. Shipping was fast. I chose them because they stand behind their work and warranty it. Would recommend to anyone in the future.
