Power Seat Control Module Replacement Cost Estimate

To check for a bad power seat control module, a technician will first make sure that a fuse has not blown. A blown fuse can be either the cause of an inoperative power seat or a symptom. The technician will also check to make sure that power is present at the control module by performing a voltage test with a multimeter. A bad control module - or a problem with the Body Control Module - may also present a diagnostic trouble code (a fault code) that can be read with a scan tool.

To replace a power seat control module located under the seat, the technician will remove the fasteners that hold the seat to the floor. This may be a difficult job if the seat is unable to move to reveal the fasteners. The seat is gently tipped forward for access to the wiring and to the power seat control module. Care must be exercised in order to prevent strain on the wires that could cause damage. The control module is located, the electrical plugs disconnected, and the retainers removed. With the bad control module out of the way, the new one is installed in place and connected. The seat is returned to its mounts and the fasteners reinstalled. On some vehicles, reprogramming of the power seat control module is necessary. If the control module is part of the switch assembly, removal of the seat may not be necessary.

RepairPal recommends that a power seat control module be replaced with an OEM part that will integrate properly with the vehicle electronics.

It should be noted that some vehicles incorporate Supplemental Restraint System (SRS) features into the seat, such as seat-mounted airbags and/or seatbelt pretensioners. Care is needed to avoid damage to the wires for the SRS and other components located in the seats.
