Best to you.

If you are experiencing unresponsive driver side power seat controls and an SRS (Supplemental Restraint System) airbag warning message on your 2008 Volvo S40 2.4i, it could be caused by a few different issues, such as:

1. Faulty seat control module: The seat control module is responsible for controlling the power seat functions. If it is faulty, the seat controls may not work and the airbag warning message may appear.
2. Wiring issue: A damaged or corroded wire connection can cause the seat controls to become unresponsive and the airbag warning message to appear.
3. Sensors issue: The seat and airbag system rely on a variety of sensors to function properly. If any of these sensors are malfunctioning, it can cause the seat controls to become unresponsive and the airbag warning message to appear.
4. Airbag module: The airbag module is responsible for controlling the airbags in the vehicle. If it is faulty, the airbag warning message will appear.

It's best to have a professional technician diagnose the problem and recommend the appropriate course of action. Sometimes, the problem can be solved by replacing a faulty module, repairing or replacing damaged wiring or sensors, but in some cases the repair may be more complex.
It's important to note that the airbag warning light should be taken seriously and repaired as soon as possible, as it can indicate a problem with the airbag system that could affect the safety of the vehicle in case of a collision.

How to diagnose this problem ? Viewing wiring diagrams to see what all is invovled in these electrical circuit's , check power supply's an ground connection's using a DMM - digital multimeter !
What type power seat's ? does it have memory ,heated an cooled etc ?
Power Seats System Description and Operation
There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function. While the passenger has 8-way power seats with heat and optional cool function. For the driver memory seat operation, refer to Memory Seats Description and Operation. Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.

If it has memory seat's there is a control module !
Battery voltage is supplied to the driver seat module through a 25 A circuit breaker. The driver seat module supplies the seat adjuster switch assembly with a battery positive reference voltage. While the seat adjuster switches are in an inactive state the switch contacts are closed to the adjuster switch common circuit.
Both right side windows have a seperate power supply from the left side window's ,has RT DOORS circuit breaker CB1 - 25amp. location left instrument panel fuse block . Circuit breaker's very rarely fail .Do the door lock's work on that side of the vehicle ? The windows won't work with their own switche's ?
The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system)
Check PDM fuse 4 15 amp ,this supply's B+ voltage to the DOORLOCK/WINDOW switch passenger side . Check for broken wires inside the flex boot from the body to the passenger door .

Instrument Panel Fuse Block
The instrument panel fuse block access door is
located on the driver side edge of the instrument panel.

Pull off the cover to access the fuse block.

The vehicle may not use all of the fuses shown.

Check wiring under the seat. Frequent habit of pushing things under the seat such as flashlights and tools etc and moving the seat forward and back sometimes pulls wires or breaks them.

You might want to try disconnecting the negative battery cable for 5 minutes and then reconnecting it. This procedure fixed my seat that was not working. It works fine now. I know it sounds too good to be true but it usually works

it sounds like the driver seat module. It controls all of these items.

CHECK FUSES AND LOOK UNDER SEAT FOR A PLUGS IN WIRE, ALOT OF MODELS HAVE THE POWER PLUG UNDER THE SEAT, TRY THAT ,ROBERT

I wonder if you dont have a bad switch. I had a similar problem on my car except that it was the heated seats that would not engage... the power seat buttons all worked just fine. I changed the switch and it fixed the problem...

Note: this was on a BMW not a Murano
