How to remove air fitting on air shocks 2003 Olds Silhouette

You can install an after market with no problems. I recommend that you get the pig tail that will fit the radio and the vehicles original harness, instead of cutting wires. The reason being is that newer cars come with a theftlock radio. There are wires that go to the bcm and ecm. You really dont want to cut into the wrong wire. A 12 volt feed to some wires can short out the bcm or ecm or security modules ( several hundred dollars plus reprogram). A $20.00 harness is well worth it.

Check the bleed port on the controller, it may be plugged with dirt. or the controller may have failed. A full funtion scanner would help find the problem.
An other option is to by-pass the auto- leveling system and install a manual scrader valve in the air line, this would allow you to add and remove air with any source. They are availble at most autopart stores.

the load sensor is probably broken. It connects the rear axle to the frame to measure load. Its mounted on the left side of the rear axle. Its commonfor these to become damaged if the vehicle is lifted by the frame rather than by the axle. Looking at the part you will probably see the sensor arm hanging loose.

Most air shocks have fittings that are also used on your car tires. If it has a similar fitting, it will more than likely fit.

you can pull the fuses, but it is hard wired so it might have relays that need to be pulled, or you can just fix it, and replace the air shocks/struts with regular shocks/struts

The simple solution is to pull the fuse for the compressor.

If you want this fixed, you most likely have a leak and will need to find and fix it. The compressor may also be rebuilding. Probably not going to be worth putting the money into fixing.

Power flushing is usually not a good thing as the heater cores can become blocked.I would suggest to remove the lower rad hose and drain as much coolant as possible.Refill with clear water with lower hose reattached.Bleed system of air as you fill with water and keep filling until operating temp is reached.Drive and return and drain it again the same way,now refill with at least 1 and 1/2 gallons of dexcool and don't forget to add the vegetable based aluminum protector required in your vehicle available from gm and make sure you bleed the air from the system from the valve just to the rear of the rad filler neck on the engine at the end of the coolant pipe running across the front of the engine.

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. 

Check the height sensor.

that could be the problem or it could be air in the stystem ....on top left of motor you will see a pipe that comes up.. on top is a small bleder screw .... remove radiator cap fill to top with antifreeze .... open bleder until just antifreeze comes out
