Download On some 2003 model year Cadillac Escalade, Escalade EXT, and Escalade ESV; Chevrolet Silverado, Avalanche, Tahoe, and Suburban; GMC Sierra, Yukon, and Yukon XL; and HUMMER H2 vehicles, the passenger door module (PDM) may become inoperative. An inoperative PDM would cause loss of function for the remote keyless entry, front passenger power window, lock, mirror and heated seat functions. Correction Dealers are to reprogram the PDM. Service Procedure Important: The labor time for performing the refresh/reprogram of the passenger door module in this recall is different than the amount of time allowed in Service Bulletin 03-08-52-001B. The labor operation code and time allowance in the service bulletin was for a BCM reprogram, and was not the correct labor operation code for this repair. Inspection Procedure Important: The following inspection must be performed in order to determine the correct repair procedure. 1. Turn the ignition to the ON position. 2. Using the switches in the right front passenger door, verify that the power window and power door lock located in that door, function properly.
