Stuck Gauges & Speedometer - 2003 2500 Hd

star2323 · March 29, 2008

I have a 2003 Silverado 2500 HD with the 8.1 V8 and Allison tranny. Today after I give the truck a good washing with a pressure washer. All the gauges including the tach and speedometer stopped working. The truck is running fine but the gauges are all stuck at the bottom.

Any ideas?

Thank you

Probably a bad cluster. Go to your local Chevy dealer, it may be covered by a special warranty policy.

THE SERVICE PROCEDURE IN THIS BULLETIN HAS BEEN REVISED. IN A SMALL NUMBER OF VEHICLES, THE GAUGE SWEEP TEST MAY NOT ALWAYS CONFIRM THE CONDITION. PLEASE REVIEW THE SERVICE PROCEDURE IMMEDIATELY.

CUSTOMERS ARE BEING INSTRUCTED TO CONTACT THE DEALERSHIP TO ARRANGE AN APPOINTMENT IF THEY BELIEVE THEIR VEHICLE HAS THIS CONDITION. THE CUSTOMER IS BEING ASKED TO PROVIDE THE VIN SO THE IPC CAN BE ORDERED IN ADVANCE OF THE SCHEDULED APPOINTMENT. THIS WILL ELIMINATE THE NEED TO KEEP THE VEHICLE OVERNIGHT. DEALERS ARE TO OBTAIN THE VEHICLE MILEAGE WHEN SCHEDULING A SERVICE APPOINTMENT. THE VEHICLE MILEAGE WILL BE REQUIRED WHEN PLACING AN ORDER FOR THE IPC.

This may cause inaccurate readings, including the speedometer and fuel gauge.

Special Coverage Adjustment

This special coverage covers the condition described above for a period of 7 years or 70,000 miles (110,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.

Parts Information - U.S. and Canadian Dealers Only

Instrument panel clusters (IPC) required to complete this special coverage are to be obtained from the Electronic Service Centers. The vehicle mileage will be required when placing an order. Refer to GM Service Policies and Procedures Manual, section 1.5.9, for specific procedures. To eliminate keeping the customer's vehicle overnight, customers are being told to contact the dealership to arrange a service appointment and to supply their VIN. Dealers are to pre-order the IPC identifying the part from the Electronic Parts Catalog using the VIN filter so it will be at the dealership on the day of the scheduled appointment.

1. The customer will contact the dealership to arrange an appointment and provide their VIN.

2. Contact a GM Authorized Electronic Service Center to order an exchange and arrange for delivery of the pre-exchange product.

3. All units will be shipped FedEx Ground (US) or Purolator (Canada).

4. After removal of the defective unit, return the defective core to the Electronic Service Center using the supplied pre-paid Automatic Return shipping (ARS) label.

5. Failure to return the product within 30 days to the Electronic Service Center will result in a charge to the Dealer's Open Parts Account.

Parts Information - Export Dealers Only

For Export Dealers Only: Order appropriate instrument panel cluster from General Motors Service and Parts Operation (GMSPO).

Customer Notification

General Motors will notify customers of this special coverage on their vehicles (see copy of typical customer letter included with this bulletin - actual divisional letter may vary slightly).

Service Procedure

Important: There are pre-programming instructions for 2003 model year instrument panel clusters (IPC). In order for the engine hours to set to their current value when the IPC is replaced, carefully read and follow the instructions below. This information is applicable for 2003 model year IPCs only. An add time of 0.1 for the pre-programming requirement is published in the Claim section of the bulletin.

2003 Model Year Instrument Panel Cluster (IPC) Pre-Programming Instructions

<LI type=1>Install the IPC. Ensure everything is connected properly. The replacement IPC requires SPS Programming and IPC Setup procedures to be performed. It does not matter which procedure is performed first. <LI type=1>Start the engine and then select IPC Setup. You must have the engine running before performing the IPC Setup. <LI type=1>Select IPC Setup. With the engine running, enter the appropriate mileage and engine hours. <LI type=1>Select "OK". Review the pop up asking you to verify the mileage and engine hours. Move the pop up out of the way if necessary to view the verification screen. This may require a click and drag of the dialog box.
Verify that the mileage and engine hours are correct and select "OK". DO NOT turn the ignition OFF until the engine has "run" for approximately seven (7) minutes. Allowing the engine to idle for this period of time allows the IPC to accumulate 1/10th of an hour and write the correct engine hour value to the permanent memory.

The engine must be running before set up is performed and run for approximately seven minutes after the user selects "OK" confirming their mileage/engine hour inputs. After approximately seven minutes, shut the engine OFF and complete the event. The seven minute clock starts after you select "OK", confirming the entries.

Note: Based on feedback from technicians, we are currently making changes to the "IPC Setup" application which will include several enhancements to the set up screens. These are scheduled to be released and available in TIS2WEB very soon.

Important: Only IPC conditions listed in the Condition section of the bulletin are covered under this special coverage program. In a small number of vehicles, the condition may be intermittent and the gauge sweep test may not always verify the condition.

IPC Performance

IPC performance may be affected by the following conditions:

• Cold temperatures

• Temperature fluctuations

• High humidity

• Driving over rough surfaces such as dirt roads or potholes

Customer Comments and Observations

Customers who describe gauge performance as jumpy, sticky, slow or erratic. Gauge performance may also be described as being inoperative or inaccurate. For example, for a period of time the speedometer may appear to move normally but be inaccurate and not return to zero (0) after the vehicle comes to a stop. This inaccurate condition may be more or less pronounced during the drive cycle and may, for a time, return to normal operation. A Tech 2 sweep test may not reveal the condition.

<LI type=1>Perform a gauge sweep test to determine/verify that an IPC gauge is sticking, stuck, or inoperative. Using the Tech 2, navigate to the following screens to perform the gauge sweep test: Body -> Instrument Panel Cluster -> Special Functions -> IPC Gauges -> Display(s) Test.

• If one or more of the gauges are sticking, stuck, or inoperative. Replace the IPC. Refer to Step 2.

• If the Tech 2 gauge sweep test does NOT verify the condition but a customer's comments and observations include information that it outlined in the IPC Performance and/or Customer Comments and Observations section of the bulletin, replace the IPC. Refer to Step 2.

• If the Tech 2 gauge sweep test does NOT verify the condition and a customer's comments and observationis do NOT include information that is outlined in the IPC Performance or Customer Comments and Observations section of the bulletin, do NOT replace the IPC. Submit a claim for Perform Tech 2 Gauge Sweep Test.

Important: If the IPC is to be replaced, record the vehicle odometer and engine hour (where applicable) value from the original IPC.

Remove the instrument panel cluster. Refer to the appropriate vehicle IPC removal and installation procedure in SI.
