Seat Memory Control Module Jeep Grand Cherokee WH WG 56038721AJ
Manufactured by Bosch (internal code F 00H J00 050), this electronic control unit (ECU) interprets inputs from the door selection switch and regulates the power adjustment motors to restore preset seating and side-mirror positions
Vehicle Applications: Predominantly engineered for mid-2000s Mopar platforms, including the 2005–2007 Jeep Grand Cherokee (WG/WH), Jeep Commander (XK),
Placement & Replacement: This hardware block links directly under the front seat adjustment tracks (often side-specific, such as the front driver or front passenger assembly depending on the market trim).
Note: If replacing this module entirely, some vehicle trims require flash programming or diagnostic calibration via an OBD-II dealer tool to fully register the communication line with the vehicle's central body control module (BCM)
