Remove the button & resolve that part of the issue,
so it either works or if tests bad-- replace it

You will need a trim shop to replace the inflatable bladder for the support if no other leaks are found..

IF THE LUMBAR IS WORKING, THE POWER IS THERE . IF EVERYTHING IS PLUGGED IN UNDER THE SEAT, THE SEAT MOTOR MAY BE FAULTY

the air lumbar is an air bladder in the seat that is inflated by an air pump. Either the Check valve in the pump has failed and not holding air in the baldder, or the bladder has cracked and is leaking. May be possible to find another seat at a junk yard that is the same as yours. Replacing the entire seat is simpler then replacing just the bladder and pump assembly.

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

there is a relay that controls the lumbar its under the seat unbolt seat replace the clicking relay

check the lumbar switch first it is an electrical switch and also vents the bag
