    Re: Answer the 1Million Question: Where is the air ride control relay located?

    Hi, how do I need to oil compressor and how to seal it from water after I open it to fix? I got CRC message on my 2003 escalade esv, had mecanic read the code it was co660-exauste valve and co585-left rear solenoid. I remove compressor open valve cover and back panel , it was wery rusty both aluminum and steel and compressor humm but coudnt turn . I clean and oil and it start, I resolder exaust valve rusted out connection, test and it work. I disconnect and clean rusty electric connection on rear gas shock solenoid,test solenoid it has the same resistance as the other, assemble everything and start engine, compressor start CRC message is gone. I didnt test ride it yet.

    Re: Answer the 1Million Question: Where is the air ride control relay located?

    Hey fellas...

    Well, There are other threads on here that go through this whole "compressor problem". Here's the deal. IF you jumpered the two large wires in the relay base and the compressor runs, 99.99% of the time it's going to be the "bleed down" solenoid that is in the compressor housing. (Cadillac cost > $500 - forget THAT fix). As I understand, the 'puter monitors the circuit to that solenoid, and if the circuit becomes open (water in the solenoid (non-sealed), and/or if the TINY wires on the solenoid or solder joints break/burn up/corrode through, the computer won't allow the control relay to pull in. When you jumper the two large wires on the relay base, you are bypassing the compressors computer command. Get on line and buy the Arnott compressor kit for less than $200, which includes a rebuild kit for the dryer (new dessicant and pads), throw it back in there and you'll be good. The compressor housing is behind the driver's side rear wheel, held on with three bolts. You don't even have to take them all the way out. Just loosen them a few turns, and it will slide out/up to get it out. Pay attention to the routing of the pressure line and the wiring harness or take a picture. The pressure line disconnects by slipping the metal wire clip around and the tube comes right out. DON'T loose the little metal clip. I left it on the tube and after driving for about a week waiting on my new compressor, it fell off on the highway somewhere. I was able to fabricate one from a paper clip and it worked perfectly. The likelihood of having any other problem is slim and NONE. Good luck.

    ----------

    Oh I forgot... just to be absolutely certain it is the bleed-down solenoid, when you take the compressor/solenoid housing out, pull the terminals, and ohm out the two wires going to the solenoid. You will probably find an open circuit.

    replaced pump w arnott about 9 months ago. service ride control pops up about a week ago, it s cold here in the NW , but the big pig sits in the garage.

    after the pump replacement, what the nex most likely candidate for failure?

    very limited tow miles on this rig, air shock bags appear to be in good shape and functional

    Ideas?:

    Possibly a sensor needs the codes pulled to be sure

    Re: Answer the 1Million Question: Where is the air ride control relay located?

    I have a 2003 ESV, replaced the dead pump about a year ago with a new arnott pump...everything back to normal.

    have never really towed anything and the shock bags look to be in good shape. pump only runs occasionally. a couple of weeks ago the service ride control message reappears and the pump doesn't seem to be firing up.

    Checked both fuses, guess the next thing to do is jump the relay, Correct?

    What else can go wrong with the system?

    Jump the relay you may have a defective compressor they have a 1 year warranty on that

    Re: Answer the 1Million Question: Where is the air ride control relay located?

    So... I am going to rebuild the solenoid in the compressor to get rid of the error message. In the meantime, I jumped the compressor and raised the truck about 1 inch. The top of back bumper was at 27"... Let it sit for about 6 hours and it has dropped 1/2"... is this normal or do I need to replace the shocks? They look great and the bags seem to be solid... The truck spent its whole life in southern TN and has 90k miles on it. Without a major leak, I doubt soapy spray would bubble..... Thoughts? I guess I can fix the valve and see what happens….

    By the way, many thanks to all of you who have taken the time to post you findings on this tread. Your hard work will save me many hours of banging my head on the garage floor....

    If it drops then there is a leak somewhere in the system try the soapy water and see if it is a shock bladder or a line as if it is the valve alone there would be no air in the shock bladders
    FYI I have came up with a way to prevent future compressor issues with this vary problem(just have to build and test it first before I post anything about it)

    The cause of the valve failure is water ingestion which messes up the valve solenoid and then causes the code which in turn makes the system go into passive mode and display the service ride control message in the drivers information screen

    cadillac man... pumped up the truck and sprayed the passenger side and had no bubbles... yea for me... When over and sprayed the driver side and sure as heck got bubbles from the front bottom side of the rubber bladder. order the new shocks and am going to try and repair the compressor. What do I need to do to rebuild the dryer....

    Order the arnott's compressor as it comes with a dryer rebuild kit as its hard to repair the compressor(I ordered mine from my local dealer since the dryer was rusty)

    Pulled to compressor off and sure as heck the little wire in the solenoid was broken soldered it back on and the service message is gone and truck inflated the shocks... They will leak down in a matter of hours, but I have new monroe 40032 on the way. Thanks to everyone that posted info in this thread, you guys saved me from buy a new compressor. Are my factory shocks worth anything? Only one of them is leaking.

    Pull the relay for the compressor as it will burn itself up in no time with leaky shock bladders
    The relay is next to the underhood fuse box
    That will save you from having to buy a new compressor

    No worries... We have multiple cars and I will not drive the EXT until I get the new shocks installed, but thanks for the heads up nevertheless....

    On another note Arnott will pay $25 each for Escalade rear shock cores. So that means that I got the new shocks that much cheaper...[COLOR="Silver"]
