Go to Autozone.com and register your vehicle for free to get the info you requested. Both fusebox details and wiring diagrams are available.

Dynaride means that your rear shocks have electronic level control. There is a sensor mounted to the rear suspension. If you add some luggage or persons to the car the rear lowers. The sensor senses this down movement and starts the air compressor which is mounted in under the hood (left fender area). This compressor pumps air into the rear shocks compensating the additional load, so the car remains at proper level all the time. If you start the engine with a delay of about 20 secs the compressor should run for a view seconds to build up the minimal pressure the system needs. If the engine is stopped also with some delay of 30 sec. the release valve opens to vent out all the air.

Hello,

Assuming you did replace with the same type of air-shock, it may seem simple, however ensure the hoses are reconnected and air tight. Spray soapy water on the air lines to check for leaks (you'll need to adjust the load to ensure pump function).
Speaking of pump function; check your pump by turning the key to ON. Wait 30 seconds and you should hear the air pump running under the right rear of the car (under the trunk next to the subframe).
If you can not hear the pump running, then check all fuses. If fuses are good and pump does not run, then it may be time for a replacement pump.

I hope this helps.

May be a height sensor that connects to the lower control arm. I got one from a pullapart salvage yard for less than $6. It fixed mine.

Take skirting down in trunk on the side you are working on. Remove center nut on shock 15MM. Then jack that side up or whole rear of car and place jack stand or jack under control arm. Now you can remove the two 10MM bolts that fasten the bottom of the shock to the control arm, most of the time the speed nuts brake but you can hold on to them with a pair of pliers. Once this is done remove the shock place all hardware on shock and install. The new shock will come with an 18MM center nut. Hope this helps.

Do not try add air.. The air ride has a pump it pumps up to need psi Adding psi can blow your shocks

Removal & Installation

1. Remove the tire and wheel assembly.
2. Support the control arm with a jack stand.
   
   Fig. Use support bracket tool J-23028-01 mounted on a jack to support the rear lower control arm
   
3. Remove or disconnect the following:
   
   Electronic Ride Control (ELC) air tube from the shock Two bolts securing the shock to the control arm Trunk trim to gain access to the shock upper mounting nuts. Cover, the two nuts, and the reinforcement from the top of the shock Shock from the vehicle
   
   Fig. Remove the cover to gain access to the upper shock absorber mounting components-rear suspension
   
   
   Fig. Exploded view of the lower shock absorber mounting to the knuckle assembly-rear suspension
   
   

To install:
Install or connect the following:

Shock, reinforcement, and the two nuts. Tighten the mounting nuts to 15 ft. lbs. (20 Nm). Shock cover Trunk trim Shock-to-control arm bolts and tighten the bolts to 18 ft. lbs. (24 Nm) ELC air tube to the shock. Tire and wheel assembly

yes there is a relay switch in engine compartment or under dash

still got air bleed more

I had this happen with my 2004 Buick Lesabre at 38,000 miles. The dealer fixed it for $68: it was a linkage bar in the rear that enabled the system to detect how high the rear was, that had become detached.

I have also read from another owner, that his sensor module for this system had become broken at around 80,000 miles, and that that wasn't too expensive either.
