Question Lumbar Supports S320

Both lumbar supports will fill up with air and after about 3 minutes both will deflate at the same time. You'll then here the pump in the rear seat and the lumbar supports in both seats will pump with air and are again fine until 3 - 5 minutes later, when both will lose air at the same time. This will continue until the pump deactivates. In order to reactivate this cycle, I pull one of the fuses in the trunk for a minute and put it back in and cycle starts all over again. I stop the cycle by not touching the fuse so I wont burn up the pump motor.

does anyone have a clue as to what might be wrong?
