Check and make sure that the level control lever that goes to your shocks was reconnected. Might have been overlooked....Hope this helps.

its a computer problem its located in the trunk in middle up under rear window theres a wire diagram that you can get to short two wires to fill the bags up

did you blow your back air shocks there should be a switch in trunk to reset air shocks when you lift your car make sure you turn this switch off if you dont you could blow your air shocks there not cheap to fix unsure the exact price

reset air shocks button should be in trunk it maybe damaged the air supension reset it see what happens

The load leveling shock will not work if there is an issue with the compressor. If you buy the sir shock's, your going to have to address the compressor issue to even have the air shocks level the Silhouette. Once you have the compressor issue addressed, the shocks it's self is simple enough to replace that you can do it with common tools to save you some money. My wife has a Montana and we had the same problem, since we do not tow and really never hold that much weight. We replaced the rear shocks with Monroe Reflex Shocks, Found the van to be much more sturdy then the air shocks ever were and the good thing about them is there were lift time replacement at Parts Source. Regardless on which shocks your going to use, it's a good rule to replace both sides at the same time. The only difference in to reinstalling the air shocks is you need to reattach the air lines to the shocks and that's simple as removing the shocks it self. The shocks are only held on by two bolts,  one on top and one on bottom and should only take about 20 min each side to do since you have to jack the car up and remove the wheel for room, but you can remove the shocks it self without removing the wheel, it's your preference. Good luck and keep me posted, be glad to answer any questions you may have. 

in rear is your control for air shocks un hook bolt conn. move lever to c if it raises or lowers have lift or jack stands under so car not pin u under

have you reset the computer by disconect neg battery cable for about 2min reconnect start engine drive it for about three blocks if that does not work when they put you tires on they might of broke the air level senser

I had this problem once, I pulled the fuse on the air compressor, then released the air from the shock, by removing the air line from the shock. Then I replace the fuse. So far It seems to work again.
Must have somehow gotten out of range for the auto-level controller, letting the air out manually reset it. Worked for me!
