Rear-end lowers after being parked on Hummer H2
After my H2 is parked awhile (mostly overnight), I will find the rear end has "dropped" approximately 6" as compared to the height of the front end. The rear end will regain its height once the engine is turned on. This happens intermittently.

I get a "service air suspension" message, the compressor runs either constantly or not at all when the message is displayed. This doesn't happen all of the time, just randomly. Sometimes it completely drops the rear air suspension and sometimes it's just fine.... Drives me crazy!
I was the second owner of my 2003 Hummer H2 and the air started leaking from the rear compressor or tank about one month after buying the vehicle, I have tolerated it until now ( about one year now ) because now I have to stop and restart it just to get 25 miles now! Any ideas what I should do next like a conversion to shocks and springs or repair/replace the expensive part ?
Rear drops when parked. Noticeably more on drivers side. Looking for the solution.
I have a 2003 hummer h2 while in park the rear loose air and it sit really low and it takes about 20 min to rise back to normal for me to drive..I could hear the compressor turn on when I start the hummer but its taking for ever to go up from the rear. What could be the problem

Over night the back end of my h2 hummer drops down but after driving during the day it stays the same height of the front . Until I get up in the morning it happens all over again.
