After looking up some info on the EAS for my 96 RR... I am CONFUSED about how to fix. I bought the rover from some a private seller. He told me that the EAS worked, but when the battery went dead he tried to jump start and the truck would not start. He said that it sat about a month till he purchased a new battery. Upon installation of the new battery he said the air suspension no longer worked. I agreed on purchasing the vehicle as is and thought I could try to figure it out and get the suspension fixed because I really liked the overall rover. Now after doing some research about the air suspension I am kind of lost. I notice how many said the EAS system was expensive to maintain, so I thought coil spring conversion... Although keeping the EAS would be nice, but the nearest LR dealer is 150 miles away.
Right now the truck is sittin LOW (bump stops)! When the ignition is turned on all the lights come on I get the "EAS FAULT". I don't what and how to test anything to figure out the problem.... Could anyone help with some troubleshooting steps? One thing I checked was the fuse under the hood that has the picture of the truck and the up/down arrows... it was Okay! When I press the up/down buttons on the dash I dont hear anything happening with the compressor.
Any help would be greatly appreciated
Thanks

Usually the way the system fails is like this: The bags begin to leak/crack...which causes the compressor to work harder and longer to maintain ride height, which causes compressor overload, which burns it out, flips the thermal switch (not actually a switch, it is an intergral part of the compressor), and kills the compressor.
The best way to do it is to catch the system before it faults out..but since you have, you're stuck. A rover scan tool can read the EAS computer, and there are a few ways to diagnose the system on your own. You can also manually jump the compressor by grounding out the wiring harness under the seat and see if the compressor works and you just blew a bag causing the fault.
Read through all the articles on RangeRovers.net regarding the EAS system diagnosis and repair:

Good luck! My EAS went out at 81k miles, and I just went for the coil conversion to save me $6000 and the trouble down the road with replacing the EAS  .

On the "Main System Components and Failure Modes" under the compressor section it states: On the 4.0/4.6, failure of compressor to operate at all can mean maxi fuse 2 is blown or Relay 20 is defunct.
The fuse on my RR is not blown, but I dont know about the relay. Do they sell them at regular auto part stores?
