CAMPAIGN: INCORRECT I/P CLUSTER BEZEL LENS INSTALLED
Subject: INCORRECT INSTRUMENT PANEL CLUSTER BEZEL LENS INSTALLED
Models: 1990 C5H, C6H, C7H TopKick Trucks With Gasoline Engines (LSO/LRO)
General Motors of Canada has determined that a small number of 1990 TopKick trucks equipped with gasoline engines (LSO/LRO) may have an incorrect lens installed in the instrument panel cluster bezel assembly. The "SERVICE ENGINE SOON" lens window incorrectly reads "SERVICE TRANS FELTER". If this "SERVICE TRANS FILTER" telltale were to illuminate, which would actually mean that engine service was required, and the operator ignored it, the potential exists for adverse vehicle performance such as poor engine performance, poor fuel economy, and/or higher than normal engine operating temperatures.
To correct this condition, dealers will inspect the existing bezel, and if incorrect, replace with a correct one. To minimize the number of customers having to return to the dealership, the customer will be asked to check for the presence of the incorrect "SERVICE TRANS FILTER" telltale.
VEHICLES INVOLVED:
Involved are 19, 1990 C5H, C6H, C7H TopKick trucks equipped with gasoline engines (LSO/LRO) and built within the following VIN breakpoints:
MODEL YEAR MODEL FROM THROUGH ---------- ------- --------- --------- 1990 GMC LJ608841 LJ609161

Dear General Motors Customer:
General Motors of Canada has recently become aware of a situation on certain 1990 C5H, C6H or C7H TopKick trucks equipped with gasoline engines. A small number of these trucks may have an incorrect lens installed in the instrument panel cluster bezel assembly. The "SERVICE ENGINE SOON" lens window incorrectly reads "SERVICE TRANS FILTER". If this "SERVICE TRANS FILTER" telltale were to illuminate, which would actually mean that engine service was required, and the operator ignored it, the potential exists for poor engine performance.
To minimize the number of customers having to return to the dealership, we are asking you to check for the presence of the incorrect "SERVICE TRANS FILTER" telltale (located in the fourth window area from the right). This can be verified by turning the ignition key on (do not start the vehicle), illuminating the lens. If the vehicle is equipped with an incorrect lens, your GM dealer will install a new bezel assembly in your vehicle. The correct lens will state "SERVICE ENGINE SOON" when illuminated. This service will be completed for you at no charge.
Please contact your GM dealer as soon as possible to arrange a service date.
This letter identifies your vehicle. Presentation of this letter to your dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.
Further assistance, if required, may be obtained from our Customer Assistance Centre, toll free by calling 1-800-263-3777, or if you live in Quebec, 1-800-263-7854.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
