GM Cluster Rebuild & Repair


GM Cluster Rebuild and Repair


With over 85 years of experience, there is no other better choice when it comes to having your GM, Hummer, or Isuzu Instrument Cluster repaired!

It's well known that certain GM and other models had high failure rates in the stepper motors used in their instrument clusters for quite a few years. Who better to fix this problem with YOUR ailing cluster than the gauge repair and restoration experts at Bob's Speedometer?

Symptoms of a failing Instrument cluster include:
  • Erratic, intermittent, inaccurate, or faulty readings on any gauge.
  • Total or intermittent cluster power loss.
  • Dimmed display or total lighting failure.
  • Sticking gauges, or gauges that don't reset to zero.
  • In extreme cases (all too common) the entire instrument cluster is completely dead.

Why it's important to repair your cluster:

There are many situations that could arise due to faulty gauges.
  • A faulty speedometer reading could result in a speeding ticket, which in turn could lead to paying thousands of dollars in higher insurance premiums.
  • A faulty fuel gauge reading could result in you or your family being stranded, in any number of unsafe locations, or in hazardous weather conditions.
  • Faulty temp, oil, or battery gauges could not only leave you or your family stranded, but could also result in thousands of dollars worth of engine damage.

What is included in our service:
  • We replace ALL of the stepper motors in your cluster with new, premium quality replacements, that far exceed the poor quality of the OEM originals.
  • Replacement or repair of back lighting and/or bulbs
  • We test and re-calibrate all gauges in the cluster.
  • We check the entire circuit board for faulty power connections and repair as needed. 
  • You original odometer reading stays the same.
  • We clean the face plate and lens.
  • You cluster repair comes with a full one year warranty without any mileage restrictions.

What is not included in our service:
  • Replacement Lenses, or lens polishing
  • Resetting, servicing, or replacing the digital odometer
  • Repairing or replacing the cluster power supply
  • Cosmetic restoration of the face plate, gauge faces, or pointers
  • Total Replacement of non-repairable clusters due to extensive circuit board damage
  • Please note that ALL of the above services ARE available, at an additional charge
  • Return shipping , handling, and insurance charges are additional, and may vary with your location and your choice of return shipping service level.

Why choose Bob's Speedometer instead of someone else for this repair?
  • Bob's Speedometer has been repairing and restoring gauges since 1929, and has been an industry leader in gauge repair & restoration for over 85 years. 
  • Bob's Speedometer has satisfied customers on every continent of our planet, except Antarctica. (Only because no one from Antarctica has sent us gauges to repair - yet!)
  • Some cluster repair shops quote how many repairs they have done in the thousands of units. We repair and restore more gauges than that in less than a year. In fact, we couldn't even begin to estimate the countless number of gauges we have repaired or restored over the years. Even numbers in the tens of thousands wouldn't make a dent in the actual count.
  • There is no need to trust your cluster repairs to someone working in their basement, garage, or someone that repairs clusters as a sideline. A faulty repair can make your cluster problems even worse at best, and require a total replacement of the cluster at the worst. Instead, trust your cluster, your vehicle, and your family's safety to the professionals at Bob's Speedometer.
  • All of our work is guaranteed, and comes with a full one year warranty, with no mileage restrictions.
  • You save hundreds of dollars over the cost of having this service performed by a dealer or auto service center.
  • For most folks, removing and replacing one of these clusters is a fairly straight forward operation, and does not require extensive auto repair experience or expertise.
  • Most Clusters are repaired in 1-3 business days, minimizing the repair delay. Customers selecting our Standard Return Shipping service will receive their clusters back in 3-4 days after they have been repaired and payment arrangements have been made. Expedited Return Shipping services are also available.
  • We ship Worldwide (local laws and import restrictions apply)
Don't be fooled by the numerous other Cluster Repair Shops that use low ball single gauge pricing tactics, free shipping gimmicks, with LOTS of fine print on their pricing.
When you compare what we are offering vs. those other guys, it's easy to see who has the best value for your dollar! We repair ALL of the stepper motors, doing the job right the first time, so you don't have to send your cluster in again to be repaired when the next stepper motor goes bad. Sales Tax, shop supplies, and all those other add-ons the other guys charge extra for are already included in our pricing. We won't nickel and dime you to death to make up for a low ball price after we have your cluster in our shop!

How do I send my cluster in for repair?

We receive US Mail, UPS, and Fed Ex shipments on a daily basis. Make sure you wrap your cluster using bubble wrap or other protective packing material to ensure it's safe arrival. If using packing peanuts, it's important to make sure that they do not get inside the cluster. Bagging the cluster securely is important if you are using packing peanuts.

Be sure to include a note with your name, return shipping address, a daytime phone number and/or e-mail address, and mention the GM Cluster Rebuild Service. Be sure to indicate if there is any additional work you would like done with your cluster. We will contact you when we receive it to finalize payment arrangements, and get your cluster repair started as quickly as possible.

Please be sure to ship your cluster complete with the cluster lens.
Shipping the cluster without the lens substantially increases the risk of shipping damage on both your inbound shipment, and our outbound shipment back to you. If for some reason you do not have a lens for your cluster, we will be happy to assist you with locating a suitable replacement!
Our shipping/mailing address is:
Bob's Speedometer

Very rarely does a week goes by that we do not receive a shipment that is damaged beyond repair because some one decided to save a few extra bucks by cramming their items into a Flat Rate Priority Box with little or no protection, when in reality they should have used a bigger box with much more room for the protective packing material needed to make sure their items made the journey intact.
The $10 or $15 that was saved on shipping is small consolation when they find out that the total price of their repairs will now be $200-800 more than it would have been if their shipment had been properly packaged. Even worse, they almost always find out that the carrier will refuse any insurance reimbursement for a package that has been deemed improperly packaged. All they have to show for the money they saved on shipping is a whole lot of heartache and aggravation instead!
Let's face it, if it's worth repairing, it's worth taking the time and effort to get it safely to us, even if it costs a bit more to do that. You can be sure that we will NEVER skimp on the packaging when we ship your items back to you!  


Gm Cluster LED Conversion Option


We get a lot of inquiries from customers sending in their GM clusters about doing an LED conversion at the same time we are servicing their GM cluster.

Bob's Speedometer cluster repair techs are more than happy to assist our customers with this type of LED conversion.

If you are sending in a GM cluster for repair, and want to upgrade the lighting to your choice of super-bright white, red, green, or blue LEDs,
our techs will perform this conversion for a flat fee of $125, in addition to the costs associated with your cluster repair.
