Hey guys, My 07 Denali will cycle the compressor at startup, but then after it runs it then shortly after starts letting air out. When I hear the very faint sound of it releasing pressure it will stop as soon as I push down on the bumper. So the valve is working properly. Why is it letting air out just after it ran the compressor ?
I have new air bags and just replaced the check valve in the compressor.

It does have a slight lean to the right. I have done the calibration and the sensors are where they should be according to the procedure. I am eventually going to manually adjust the passenger side sensor to match the drivers side height.

This forum is proving to be quite useless. Pretty basic question for anyone who's had a "trailvoy" with air ride.....

I guess what I'm looking for, is this normal ?

BTW I did adjust and correct my lean by adjusting the sensors.
