Roof Door Module (RDM) Service

This is a module “return to service” provided by Simple Engineering, LLC that will refresh a failed Chevy SSR Roof Door Module (RDM) for all year models.  We work on all part numbers of RDMs.  There are two GM part numbers for the RDM and 5 known “VT numbers” on the boxes.  Here’s a summary of the numbers that were originally installed by the factory: GM 15134308 (03-04) used VT119199 on the early 2003 and VT121772 on later 2003 and all 2004 GM 15828426 (05-06). used VT125367 on the early 2005, 127473 on late 2005 and VT128654 on later 2005 and all 2006 If your RDM has failed*, you can send it to us for testing and refreshing. Once the necessary work has been completed we will return your RDM in working order. There is no further programming or other activity involved, you simply plug it back in! The fixed price includes all test & repair and all the fees for return shipping by FedEx Air, “Insured” and “Signature required”.  For International customers, we may choose to return your module via DHL. ⚠️ * PLEASE NOTE:   With only a few exceptions, a failed RDM will “typically” meet most or all the following conditions: Air Conditioning – non-operational Power windows – non-operational Convertible roof – completely unresponsive Cargo (bed) cover – will not open electrically If you have a 2005 or 2006 with the gage pod on the console, the temperature indication will be inoperative. If you have a 2006, the Outside Temperature indication in the IPC will be inoperative. All other cabin features (Radio, Instrument Cluster, Seats, etc.) operate normally.   Your roof door module is valuable. For a smooth and speedy transaction, please read all of the following information prior to shipment: If there are additional problems (radio, instrument cluster, seats not working, etc.), your RDM may not be at fault and you should conduct additional troubleshooting with a qualified mechanic or repair shop. Your RDM will be fully inspected and tested prior to a refresh. Should your RDM appear to be working when it arrives, it will go through very thorough bench testing and validation on my SSR before returning to you.  Your bill will be for processing, inspection, testing and return shipping fees (typically $200).  The balance of funds and your RDM will be returned to you. To avoid this cost, please be sure to confirm that your SSR is in good working order (including a fully charged battery) and the 5 conditions listed above are present. �� Removal and replacement For a step-by-step DIY guide to removing and replacing your RDM, click on “INSTALLATION INSTRUCTIONS” in the left-hand menu or click here.   ✅ BEGIN THE PROCESS BY PLACING AN ORDER: The INVOICE number will be your return authorization.
