jphearn, Were the rear lift/dive sensors the problem. I just replaced my front and rear with Monroe shocks and WOW, what a difference the ride is. They needed replacing badly; however, I now have the same problem as you. The rear shocks will not deflate, they stay tight as a tick all the time. I haven't heard the pump kick on but once when it filled the shocks with air that was it. Been about two weeks since I replaced them and they are still tight with air and it looks jacked up in the rear. I read through 9 pages of posts and only two or three had this problem but none posted a fix. Thanks,
The compressor should make a puffing noise letting air out after the truck is turned off. Mine usually does it after my family of 5 exits the truck, as the system re-levels. Maybe the exhaust solenoid on your compressor is not working? Did you replace the compressor when you replaced the shocks?
I had my rear shocks and compressor replaced last week. I saw that the rear was noticeably higher than it was with blown shocks and compressor which looked level. I thought i might have the same problem as you. I never heard it run on start-up or release on shut down. Today I went back to my mechanics shop and opened the drivers window and got out and closed the door with the motor running. I reached through the window and turned off the key and jumped to the rear tire. There it was, PSSHHHHHHT. It was working. On the way home I looked a a lot front and rear wheel wells of Yukons, Tahoes, and a few Escalades. They were all noticeably higher in the rear.
