Power lumbar support just clicks/whirs.
First of all, Happy New Year! I am a first time Jeep owner and thrilled with my new custom built 2018 Trailhawk. I have a question about the power lumbar adjustment (4-way) switch on the driver's side seat. When the forward, up, or down positions of the switch are pressed there's only a fast clicking/whirring sound with no changes to the lumbar support. When the aft position is pressed, nothing happens, not even the clicking. Bottom line, the control doesn't work. Does anyone know if this model uses a compression pump to pump up a bladder, or a physical support inside the seat that is supposed to move? I'm not taking it to the dealer just yet 'cos I'm not anxious to have the new seat taken apart unless it's absolutely necessary.
Thank you for your thoughts.
