I have a 2005 Escalade and have had problems with the air ride for about the last year. The problem, I think, is that it runs for about a minute then is off for a while (less then 5) then runs again. It does this ALL the time, people full or empty. I finally got a message for a suspension failure and they fixed it by changing the compressor and a kinked hose. However it still does the same behavior of running a lot. I am afraid that the compressor is going to burn out again. I have squirted soap under the car to see if I could find a leak but can't see anything (but I wouldn't count on that).
Is this the normal behavior? What else could it be or where I should look.
Have you sprayed the rubber boots located at the bottom of the shocks themselves? This is where my shocks leaked air (also a 2005) causing the compressor to run intermediately. I replaced the air shocks with Arnotts remanufactered at about $400.00.
There is really no inexpensive way of resolving the problem correctly.
there may not be an inexpensive way to fix it correctly but I have a really cheap way to fix it temporarily that has been working for me. Remove each of the rear sensors, they are bolted to the frame with a single bolt, stick a washer in between the bracket and the frame and then reattach... test. You may need to add another to shorten the run time more but this changed my run times from about what yours was running to about 7-10 seconds and rarely thereafter while running(as far as I can hear it anyway). My boots dont show signs of leaking but I have a theory...
After time your vehicles springs start to settle and therefore your ass end will sit a bit lower to the ground. The OEM ride height settings dont allow, nor account for this and therefore the only way to compensate is for the system to air your shocks up enough till it reaches its original stock settings. I was having to drive around before with a really aired up rear which was unusually harsh and bouncy. Not anymore... plus it seems to be functioning fine when I do pull a load or cram it full of people and stuff.
You would think that the engineers would have thought of that
well considering that most of our rides dont exhibit these problems til after the factory warranty runs out, I dont doubt that the engineers did think of this problem. What a great way to sell lots of shocks and ride compressors CP instead of warranty!
