07 Yukon Denali rear swaying on highway

I guess they are? How would I know if they are working right or not? Is there a way to test the air pump as well?

put a load in back
get soap and water and spray bottom of bags
and when rear lifts up see if bubbles come out

How much of a load (lbs) will trigger the pump to come on?

The pump should come on for a short period when you start up your truck.

Well just looked at the compressor I unplugged the air line from the shock and nothing.....no air sound or hiss. I would guess the air pump and rear shocks need replacement? Crazy thing is I have zero warning lights, no engine lights. If the system was bad or leaking air wouldn't it give me a warning message of some sort? Unless the previous owner pulled the fuse. Can someone tell me which fuse controls the compressor please. (A pic would help)

Thanks

Ok help me out which one is the air ride compressor fuse?

In all actuality if the fuse was pulled a warning message about servicing the suspension would show up. The only way it wouldn't was if a resistor was connected inline to the pump.

#71 - STUD 1 for the compressor
