Drivers side lumbar buttons not working

[tnbuilder]

My drivers side lumbar buttons are not making any adjustments to the seats. I am assuming to save weight both top and side lumbar buttons inflate/deflate a bladder. When I hit the forward and up position buttons I hear what sounds like an air pump running. The other two buttons do not make noise, but I am assuming they just bleed the air off. Anyone have this issue, if so how was it resolved? The passenger side seems to function as it should.

If this ever happens for anyone else...it was a pinched hose. Dealer fixed it.
