Rear Seat Switches
There are three push button switches that are used to operate the power folding seat; front stow switch, rear stow switch, and recline switch. The front stow switch is located in the right rear quarter trim panel just behind the second row seat. The rear stow and recline switches are located in the right rear trim panel just inside the liftgate. Battery positive voltage is supplied at all times to all three switches from the FFS SW Fuse located in the left rear fuse block. The folding seat will operate only in a supervised mode, i.e. press and hold the selected switch button through the entire cycle of operation, or release the switch when the desired seat position is reached. When any folding seat switch is pressed, it sends a 12 volt signal through the switch signal circuit to the RSM. The RSM then commands the appropriate seat motors to move in response to the switch signal.
Rear Seat Module and Power and Ground
The rear seat module controls the position of the third row seat. When commanded it moves the seat from the seated position to the stowed position, or, from the stowed position to the seated position. With the seat in the seated position, the RSM can also move the angle of the seat back forward or rearward.
Battery positive voltage is supplied at all times to the module through the battery positive voltage circuit and the FFSM fuse located in the left rear fuse block. This voltage is used to power up the RSM and also to apply power to the seat motors when commanded. The RSM is grounded through the module ground circuit and G401.
The first place to start would be check the fuse's .Do you know where the left rear fuse block is located ?
Fuse Block - Left Rear
In the passenger compartment, near the left side of the rear seat under the carpet
If the fuse is good next thing to do would be ,have check for DTC'S in the rear seat module ! This has nothing to do with check engine light or OBD 2 diagnostic trouble codes an a code reader for said OBD2 codes will not work . Would need a factory scan tool to check these codes.
Battery positive voltage is supplied at all times to the rear seat load floor switch and the rear seat position switch by the rear seat module (RSM). The RSM monitors these battery positive voltage supply circuits for the protection of internal circuitry of the module.

Battery positive voltage is supplied at all times to the seat adjuster switch and the memory seat module (MSM) through the same circuit. The MSM uses this battery voltage input to determine if battery positive voltage is applied to the seat adjuster switch.
