This bulletin cancels and replaces bulletin 03006 issued April, 2003. The service procedure has been revised. Destroy all copies of Bulletin 03006.
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1997 Chevrolet Blazer and Suburban; GMC Jimmy and Suburban; 1998 Chevrolet C/K Extended Cab Pickup, Astro Van, and Suburban; and GMC Sierra Extended Cab Pickup, Safari Van, and Suburban vehicles equipped with electric outside rearview mirrors. Under certain conditions, some of these vehicles may develop a short circuit in the electric outside rearview mirror switch. If this were to happen, it could result in an inoperative switch, heat damage to the driver's door and/or ignition of components in the driver's door and a subsequent vehicle fire without prior warning.
Dealers are to install a fused jumper harness to the electric outside rearview mirror switch.
Involved are certain 1997 Chevrolet Blazer and Suburban; GMC Jimmy and Suburban; 1998 Chevrolet C/K Extended Cab Pickup, Astro Van, and Suburban; and GMC Sierra Extended Cab Pickup, Safari Van, and Suburban vehicles equipped with electric outside rearview mirrors and built within these VIN breakpoints:
Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) or DCS Screen 445 (IPC only) before beginning recall repairs. [Not all vehicles within the above breakpoints may be involved.]
Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the recall bulletin. The customer name and address data furnished will enable dealers to follow-up with customers involved in this recall. Any dealer not receiving a computer listing with the recall bulletin has no involved vehicles currently assigned.
These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this recall.

Important: An initial supply of parts required to complete this program will be pre-shipped to involved dealers of record. This pre-shipment is scheduled to begin the week of April 14, 2003. Pre-shipped parts will be charged to dealer's open parts account.
Additional parts, if required, are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO=Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO=Customer Special Order.
Harness Kit, O/S RR View Mir Body Wrg
Important: The following REVISED procedure provides instructions for installin an in-line fuse wiring harness at the exterior power mirror switch located in the left front (driver's) door. This revised procedure does not require the disconnecting and reconnecting of the negative battery cable that was included in the original procedure.
Notice: The steps in the following procedure must be followed in the exact order that they are written. Failure to perform these steps in the order written may result in damage to the fusing circuits contained in the recall harness being installed.
- Open the driver's door and verify that the exterior power mirrors function properly.
- If either or both mirrors do not function properly, refer to the appropriate Service Manual for the diagnosis and repair BEFORE proceeding. If the problem is related to the power mirror switch and/or related wiring, the repair should be handled as a goodwill adjustment with Area Service Manager authorization, if required. If the problem is related to the motors in the exterior power mirror assemblies, the cost of the repair is the customer's responsibility.
- Remove the panel (bezel) that holds the power mirror switch. Refer to the Doors subsection in the Body and Accessories section of the appropriate Service Manual if additional information is needed.
|• ||On C/K and S/T model vehicles, using a flat-bladed tool, carefully pry the bezel up from the door trim panel.|
|• ||On M/L model vehicles, carefully remove the screw covers on the assist handle. Remove the assist handle screws and the screw attaching the front corner of the bezel to the door trim panel. Carefully pull the bezel away from the door trim panel.|
- Disconnect the electrical connector (2) from the power mirror switch (1) and remove the terminal position assurance (TPA).
- Using GM 12094429 (electrical terminal release tool) contained in J 38125-B (Terminal Repair Kit), remove the terminal and orange wire from cavity "H" (1) of the harness electrical connector. The letter "H" can be found on the harness connector.
- Take the terminal and orange wire removed from the harness electrical connector and insert it into cavity "A" of the two cavity loose connector provided in the recall kit. The letter "A" can be found on the connector.
- Using GM 12094429, remove the terminal and brown wire from cavity "G" (1) of the harness electrical connector. The letter "G" can be found on the harness connector.
- Take the terminal and brown wire (1) removed from the harness electrical connector and insert it into cavity "B" of the two cavity connector. The letter "B" can be found on the connector.
- Verify that both terminals are locked in the connector by LIGHTLY pulling on the wires.
- Insert the gray terminal position assurance (1) included in the recall kit into the end of the connector where the two wires stick out. When properly installed, a "click" type sound will be heard.
Notice: To avoid damaging the fusing circuit contained in the recall harness, DO NOT connect the two cavity connector that you just assembled, to the recall harness two cavity connector UNTIL INSTRUCTED TO later in thsi procedrue.
Important: The two wires must be installed in the correct cavities of the connector in the next step. The cavities can be identified by a small letter (G & H) located on the connector.
- Take the two wires and terminals located on the end of the recall fused wiring harness and insert them in the two cavities in the electrical connector that was disconnected from the power mirror switch.
|• ||Insert the BROWN wire and terminal (2) into cavity "G".|
|• ||Insert the ORANGE wire and terminal (1) into cavity "H".|
- Verify that both of the terminals are locked in the connector by LIGHTLY pulling on the two wires. Then install the TPA.
- Take the new two-cavity connector (1) that you just installed the two wires into in Steps 6 and 8, and plug it into the recall fused wiring harness two-cavity connector (2). When properly installed, a "click" type sound will be heard.
- Connect the harness connector to the power mirror switch. When connected, the completed assembly should appear as shown.
Important: If the power mirrors do not operate in the next step, turn the headlamps to the ON position and retry the power mirrors. If the mirrors operate with the headlamps ON, but do not operate with the headlamps OFF, you have installed the wires incorrectly (crisscrossed) in a connector.
- Verify that the power mirrors operate correctly.
- To prevent rattles, wrap the fused wiring harness as shown with foam tape (1) included in the recall kit.
- Reinstall the bezel in the door trim panel.
On M/L vans, tighten the screw to 5 N·m (44 lb in).
- Install the GM Recall Identification Label.
