The compressor for the air ride stopped working, went to junkyard biught another however, still nothing. does something need to be reset or am I forced to pay $600.00 for a new one?

I presume you replaced the damaged loom and cleared the OBD codes.

Is there power getting to the Compressor for the Air Ride? If there is, then the Compressor went SOUTH. If no power, you need to trace it back to the Power Source (Fuse Box)....

Remember that the Compressor needs Power to Operate and if it has Power, then it is the Problem

Putting on a car lift without turning off air ride won't affect the system, to reset the air ride system requires a code scanner and plug into port, try calling some auto stores to see if they can do this or have a cheap unit to reset, or take back to garage and fight with them to reset, or go to different garage.

Unfortunately, it sounds like the air compressor for your air ride system is not working. But before you replace make sure that the height sensors haven't gone out which would bleed deflate the bags. SunCore Industries has about the best prices for the air compressor, dryer and air struts and bags.

Changing them is no picnic, but there is plenty of information at SunCore on step by step instructions to do it.

I have a 96 Mark VIII and have had to replace the rear bags and two height sensors and the air compressor so far, but when they work as designed they are a very smooth ride. A friend went with the replacement non-air ride and there is a big difference in how it rides.

YOU NEED A STAR 2 TESTER 007 - 0041 - A OR DIAGNOSTIC EQUIPMENT THAT IS EQUIVALENT TO TURN ON AIR COMPRESSOR TO TEST AND REGULATE AIR TO AIR SPRINGS. ALSO RESET THE AIR SPRING COMPUTER.IF YOU NEED TO RELEASE AIR FROM AIR SPRINGS TURN OFF AIR SUSPENSION SWITCH.THEN REMOVE AIR SPRING SOLENOID RETAINING CLIP,ROTATE THE SOLENOID COUNTERCLOCKWISE TO FIRST STOP, THEN PULL SOLENOID STRAIGHT OUT SLOWLY TO THE SECOND STOP UNTIL ALL AIR BLEEDS OUT AIR SPRING, THEN REMOVE THE SOLENOID. YOU COULD HAVE DAMAGED FRONT AIR SPRINGS WHEN YOU CHANGED OIL WITH OUT TURNING OFF AIR SUSPENSION.WHICH CAUSED AIR SPRINGS OVER EXPAND DAMAGING THEM.

my compressor for my air ride suspension went out,so i changed it and now i cannot get power to my compressor.

usualy the front berring goes out of those and yes it is loud. just find one off a low milage vehical at a junkyard have it installed just dont have it charged or pluged in than the pully will be there for the belt to ride on but the air conditioning will not work. a used one will save a lot of money. charging the system is also very expensive. but all in all yes you need it becaus the one belt runs power steering altinator a/c watter pump.

The compressor is underneath the airbox in the engine bay. NOT in the trunk

located on the air suspension pump, there is a air fitting on top which you can inflate with an air hose, start the car and when the pump comes on, add air......it should stop pumping when the ride height sensor gets to the adjusted height....hope this helps....GL

It could be a wheel speed sensor that went out or something... When working with the wiring, something could have just gotten crossed or tapped to get these codes as well. The compressor shouldnt be running anymore if everything was tied off properly. Take it in somewhere and have the codes cleared and that should fix the problem hopefully. I know AutoZone has a reader, but I do not know if they have they ability to clear the codes.
I hope this helps.
