Does the bcm ona 08 gmc acadia control the power seat on drivers side

Question edited for clarity.
Question moved from Spanish Car company 'Seat', pronounced See-At.

Check Fuse 13 (Heated Seats)

Does not use a turn signal relay flasher. Computer controlled by the BCM - body control module .

Door Lock System Components
The power door lock system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Door lock relay--Located in the instrument panel (I/P) fuse block and controls the locking of the rear doors.
• Door unlock relay--Located in the I/P fuse block and controls the unlocking of the rear doors
• Body control module (BCM)
• IP BEC
• Reversible door lock actuators in each door

Driver and Passenger Lock System Operation
The front power door lock switches are integral components of the driver door module (DDM) and passenger door module (PDM). The switches are two-position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDM or PDM. The DDM or PDM monitor these inputs and send a LAN message indicating a change in the switch position. Modules, that activate the power door lock motors, receive the LAN message and activate the motor in the appropriate direction to lock or unlock the vehicle doors. The body control module (BCM) upon receipt of a lock or unlock signal will control the rear door lock or unlock relays and also send a LAN message to the DDM and PDM to perform the commanded function.
The modules that activate the power door lock motors are:
• DDM (driver door lock actuator)
• PDM (passenger front door lock actuator)
• BCM (both rear door lock actuators)
The DDM and PDM are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other, causing the doors to lock or unlock.
The rear passenger doors are controlled by the BCM through the rear door lock/unlock relay which is incorporated onto the printed circuit board in the LH BEC. The BCM controls the unlock relay by providing ground to energize the coil and controls the lock relay by providing battery voltage to energize the relay coil. This energizes the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. Since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.

Seat controls and drivers memory all go through the body control module. Make sure you have not popped a fuse. It will be a high amperage one. If the fuses are all good, then look at the BCM which is under the drivers seat.

First, find the fuse and/or the relay that controls the circuit, and verify the fuse and/or the relay is good.
Although you may find it nearly impossible to do, unhook the wire to the seat motor at the coupling underneath the seat.
It may be underneath the carpet.
Test the wire plug, with the ignition key on and the seat electric seat position lever/button pushed, and see if there is electricity to the seat.
If so, you may need a new motor.
If not, test the switch to see if electricity is getting to the switch.
If so, you may need a switch.
If not, a GMC or a Chevrolet dealer may be in your future.
God bless your efforts.

Try to go to a near by autoparts store and have them test your fuses, it's free. They can also do a lot more. Good luck

The BCM is attached to the fuse block under the second row seat on the drivers side.

reconnect and the connect back the cabel joint under ther the driver seat

probably a fuse or relay, but check your owners manual because I think some GM models will not activate the heaters in seats if the ambient temp is above 70 degrees.

both the rear passenger side wont unlock ???? How many doors are on the passenger side ? Or both back doors don't unlock ? Two relays lock / unlock the back door's Not the lift gate . The BCM controls the relay's . The relay's are located in the rear fuse box . Under back seat .
