My drivers side power seat not moving but i can hear the power working when i hold the switch. fuses and circuit breakers good. why wont it move?

Check in the under hood fuse block or power distribution center for fuse #72 and #75 these are 60 amp fuses. If the problem isn't there you have Two separate problems, check at the switches for battery voltage and ground. The most common problem is switches.

Easiest thing to check first is the fuse. If that's good. I'd disconnect the plug at the motor and see if it's getting power when you try to move it.

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 .

Check the fuse and circuit breaker "A". I have the same problem except I am missing the circuit breaker. There was a circuit breaker that was jury rigged with some wires that worked for awhile until the wires broke.

well, check all your fuses and circuit breakers,next would be to check the connection at the swith, cad use a test light and also check for power and a good ground at the motors,it unlikely that all postions would stop at once and it be a motor,if they all stopped then its gottta be a fuse or switch or wiring.

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

There should be a Circuit Breaker located within the Wiring Harness under the Driver Seat. Check this breaker and also the Ground.
There "maybe" also a Relay located between the switch and the motor. Check for voltage to this relay, and also this Ground.
With the Engine OFF: Try to move the seats in all directions. If the motor clicks, and the seat doesn't move: the Motor assembly must be replaced.

check fuse.if fuse is good check for power at seat motor.if yes replace seat motor.if no check wires at switch.if wires is not loose or broken seat motor switch could be bad.

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
