Does anyone know how often the air ride pump is supposed to cycle on and off? I'm sitting in the car with the kids waiting on the wife in the store and my pump is coming on about every minute. I stood outside for a bit with my leg against the running board and I can feel the ride height go up when it turns on but don't really feel it go down. Maybe because the shocks bleed off slower than it fills up. But anyways I am just wondering what the acceptable limit is before I need to start worrying about leaking shocks. Thanks.

Could also be a leak at the compressor. Agree it should only come on when the truck is first started or if you put a ton of weight in it. You should also be able to feel your shock bladders. They should be rigid, and not soft. The compressor should not be running that much.Nice Ride said:
It's an 08 esv with almost 100K miles. We just picked it up a few weeks ago. Is there a procedure that I can to to isolate the leak? In not a dummy when it comes to mechanical work. I just don't wanna pay a dealership to do something if I can do it. I squeezed the driver rear shock and I could tell it had air in it but it wasn't hard. There was some resistance.
It should be really firm. Check them again in the morning after the truck has sat. Bet they are completely empty. You need to spray the shock bladders down with soapy water and look for bubbles. I'm guessing it's the shocks. Might even want to swap out the compressor. Dorman makes an easy plug & play swap out. You can find everything on Amazon and will save you a ton of money as it's fairly easy DIY project.mxer0022 said:
I got the hose kit for the compressor costed around 100$ it comes with a hose that connects to the left rear air shock the pump and the hose that is going to the right rear air shock. I put the escalade on even ground and disconnected the battery and rest the system and now I am good. So before you get shocks and a new pump you should try the hose kit first. I use to get the pump running periodically and I knew it could not be the shocks since they was replaced 6 months ago. I was going to get a new pump but I tried the hose kit first and I was successful.
There is a know issue with a connection on the pump. Google it on the escalade. Its a cheep piece before you do the lines. I agree with the soapy water test on everything. Pit weight in the truck, as soon as it pumps up start spraying... be patient.... In my opinion, I would stick with all stock items.
I just went through this with my 2008 Esky. 88k miles and the rear shocks went out. Ext warranty picked up the tab, 4k miles later and the new ones exploded per dealership (both sides). New shocks again and a new compressor this time.
It rides like new again, u will definitely feel a little bounce here and there when they aren't working properly.
Good luck !
