07 Denali, Level-Ride Air Compressor not kicking in

[Rayaz_XL]

I have an 07 Yukon Denali XL. When I just got my truck 2 years ago, everytime i started the truck id' always hear the air compressor start up and run for atleast 2-3 mins, especially when i have a heavy load you will hear it run and inflate the airshocks.

 

I noticed for a long period f time I do not hear it operate at all, what diagnostic check can be done, also what do you think the problem is? Thank You!
