Replaced air bags on suspension now the bags will not inflate

Suspect dirt or foreign objects inside lines/tubes from compressor to the bags.
Also could be collapsed lines.
Add an air pressure gauge to the lines to see if the compressor is inflating the proper air pressure.
Try inflating the new bags with an outside source.
God bless your efforts.

These Lincoln air suspensions are terrible. I have converted many over to coil springs at a fraction of the cost of replacing/repairing the bags. If the rear bags don't inflate, there is a broken air line to the bags or the bags are leaking

If You are referring to the Air suspension System then You Have a Leak in the Line diverter Bell, It look like a bell with 5 r 6 1/4 in Plastic Lines coming out of it, try Spraying it With Soapy Water to see any air Bubbles, if this is the Case replace the Bell or the O-rings on the Lines, or both ,also Check the Lines going into the suspension Bags, If the Bags themselves Have any Cracks in them then You need to replace the Bags, Fairly Expensive, and Unless You are a Tech Dont try this @ Home since Major Bodily Injury can Occur, If Not following the Correct Procedure's to replace the Bag Suspension SYStem

Probably failed seal or air bag leaking air. Check again and try to see if this will do the trick. Sometimes pvc line could fail to deliver air to the bag too!

You will have to turn the air ride system off until the bag is fixed. Otherwise the pump will run continuously trying to fill the bag. This will obviously kill the battery.

check the air compressor for the air bag should be around the top of engine

Save your self the hassle and expence of troubleshooting and replacement parts, install a suspension retrofit kit which changes the rear bags to coil springs and the front to struts. A car this old you might as well start over for less than $500.00......

need to make sure no fuses are blown and also make sure the air ride button is still on

Hello;
The inflatrion air valves have probably gone bad. You can buy the valves seperate from the air bags but make sure your bags are in good shape. The air valves come (or did) with the new air bags. May be time to replace the rears with new. Hope this helps, please rate me high;

Your airbags probably have an air leak or are just starting to crack. Go to you tube and type in Suncore hummer suspension air bag replacement. They have a whole how to install that also show your suspension and how it fails
