Question
I have recently had a major problem with my envoy. the air
suspension was perfectly fine and just this morning i went to
drive it and my vehicle was nearly sitting on the ground. the
compressor is not going on and i have checked the fuses. it
drives so rough i can barely stay seated. any ideas?

Answer
Samantha,
  As stated in my profile, I'm a Parts Expert, NOT a tech but I have looked at everything I can to help you.
  All I can come up with would be a relay. I have looked in Standard Ignition, Borg Warner and A/C Delco and can find no relay.
  All I can guess is that the relay, IF it has one, is a G.M. item only. You should call your local G.M. Dealer.
  I'm sorry this is the best thing I can offer. Again, I'm NO Tech!!
  In the mean time, the only suggestion I can make is to get one of those "plastic doughnuts" that women use after having a baby and put it on your seat in the truck.
  I hope this helps and hope my humor wasn't offensive. Good luck..
