could be a faulty component in the kit supplied to the mechanic

is it a four bag kit ?

Under the console, between the seats. Have the codes read first. These modules aren't cheap.

well I will tell you my problem it maybe the same happening to you, every time I park the car for more than 4 hours it will lower the rear and after I start it will go to normal high, well the car have a air leak on one of the air bags in the rear, the compressor was pumping air almost all the time because of that to the point that one time just stop working. I have to buy new air compressor and 2 air bags. I bought them at www.arnottindustries.com not difficult to replace either.

I replace both rear air springs on my envoy denali and it it still wornt inflate all the way up and u could hear the compressor working what can I do to fix the problem

You will need the computer scanned to find out what the problem might be.It could be a sensor or could be a module that is faulty.

May something wrong with the airbag. You can have a try of airbag reset tool. inexpensive and easy to use.

The air suspension system should stay up for several days without going completely down, which probably means that you have a small leak which is quite common even on relatively new air bags or struts.

A general rule of thumb is that if the compressor isn't kicking on several times during a drive then they are good to go. The air bags are a pain to change, so most people don't change them until they are really bad.

they are bolted in a not to hard to remove once the air is drained from them however you can not drive it without the air bags. It will bounce way to much to control the truck.

yes you must have a leak somewhere. maybe in the air bags or the lines. jack up the car while there is still air in the bags get some soapy water in a spray bottle and start spraying the air bag and lines and pump until you find the leak. then replace whats needed.
