There is no air ride in the LS,..maybe your thinking Mark VIII or Towncar??

Yes. You can modify the ride height sensors to lower the vehicle. There are instructions online!
attached to a link to one of the rear lower control arms
compressor relay
possibly the height sensors came unplugged rear or front but that will dissable the pump.
Right next to the master cylinder.
There are two sensors, one on the passenger side of the rear axle and one on the drivers front lower A-arm. They are variable resistance switches with adjustable mounts. If you intend to do any service to these, be sure to turn off the suspension with the switch located in the passenger floor well. If you move these sensors with the suspension active, that is inviting a world of hurt or possible death as the vehicle will move as it attempts to right itself and could knock it off any jacks or stands you have it on. If your ability or experience is not up to this, please leave it alone.
