"Rainman13"......On the driver's side, just in front of the rear wheel is a louvered door with barrel locks. Unlock this door and lift up. Behind this door is the das A/C condenser (looks like a radiator). It has the same barrel lock. Unlock this lock and the condenser swings out and will support the outer door.
Look inside the bay and you'll see a large pump/tank laying on it's side. It will probably be filthy from fluid leakage and road dirt. You should spray it with a good cleaner and rinse with water. Getting dirt in the system will cause make your needle valves not to seat and cause the jacks to slowly retract. In the center of the tank will be a breather cap, which is also the fill cap.
Lower your front jack 6", open your driver's window and turn the ignition switch to either ACC or ON, which ever position that will make your jack alarm sound. (You'll need to be aired up or you'll hear the low air pressure alarm.) The window is opened so you van hear the alarm sounding from the tank while filling it.
Go to your tank and start filling it slowly with ATF. At some point you should hear the alarm shut off, which means the tank has the correct amount of fluid.
While you're in that bay, there should be some "T" type valve handles. These are the handles you turn if your pump quits and won't retract. They will release pressure on the jacks and the springs will bring them up.
