Power Sliding Door Module

General Motors has decided that there is a software error in the power sliding door control module on certain 1999-2000 'U' Vans equipped with power sliding door (RPO E58). The power sliding door may stop working if any of the power sliding door controls (key fob, pillar next to the door, overhead console) are activated while the door is in the first eight to ten inches of opening travel. The door will still operate properly in the manual mode. If you experience this condition before having the vehicle serviced for this campaign, the power sliding door function can be reset by following the procedure on page 2-30 or 2-31 of your owner's manual.

To prevent the possibility of this condition occurring, dealers are to inspect for the correct power sliding door control module and if necessary, replace the module.

Important: Many vehicles between the VIN breakpoints listed below were repaired at the assembly plant before shipment to dealers. It is imperative that dealers confirm vehicle eligibility through VISS (Vehicle Information Service System) prior to beginning campaign repairs.

Involved are certain 1999 and 2000 'U' Vans equipped with Gen II power sliding door (RPO E58) and built within the following VIN breakpoints:

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 campaign bulletin. The customer name and address data furnished will enable dealers to follow-up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

Important: An initial supply of modules required to complete this campaign will be pre-shipped to involved dealers of record. This pre-shipment will occur the week of August 16, 1999. 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" prior to ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered as CSO = Customer Special Order.

Customers will be notified of this campaign on their vehicles by General Motors (see copy of typical customer letter included with this bulletin - actual divisional letter may vary slightly).

An additional labor operation is provided for customer vehicle fuel fill (see claims section). This service is intended only for retail sold customer vehicles, and should not be claimed for demonstrator or other dealer-use vehicles.

All unsold new vehicles in dealers' possession and subject to this campaign MUST be held and inspected/repaired per the service procedure of this campaign bulletin BEFORE customers take possession of these vehicles.

Dealers are to service all vehicles subject to this campaign at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such customers a copy of the customer letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the customer will not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

Important: Refer to the special video tape provided for previous campaign 99016 (April, 1999), and also to the booklet in the Certified-Plus Training (CPT) package for U-Van Power Sliding Door, #58001.00-B if additional information regarding the procedure for module replacement is needed.
