I check the fuses under the hood they all seem fine, what would cause the air compressor not to turn on?

Hello,

9 times out of 10 it is the airbag (spring helper) that has a hole in it which turns the pump off, here is the wiring diagrams so you can see how the system works and how to change out the airbags. Check out the diagrams (Below). Please let us know what happens.
