I have leather buckets and the power lumbar on the drivers is inop. I tried a switch from one that works and that is not the problem. Is there a way to deflate (without putting a hole in it!) until I get it fixed? Is it an air bladder? Is the pump under the seat?

Ok so I looked into it more last night and it is not an air bladder. There are five wires in the harness at the motor and two have 12 volts when you hit the switch. Doesn't matter what way you hit the switch they both still have 12 volts. I am guessing one of the other ones is a ground, any idea what the other two would do? Should there be power to them? Any way to test the motor? Anybody know the size of external Torx to take the seat out?
