We have a 2006 TrailBlazer SS with rear air bags. Why GM didn't use a nice simple system like they had in GMC Generals or like Peterbilt or Kenworth uses makes no sense. The truck will empty the bags every so often for no certain reason. It could sit for 4 hrs. or 24 hrs. 8* out or 48* seems to make no difference. Reading the confusing big words in the service manual just leaves me confused.Spraying the leveling devices with Silikroil helps, but they are only electric and have no air going to them. The truck has 175k on it and I feel if I was to spray something in the air intake of the compressor it might upset things as it will fill up when started and ride fine. Thanks in advance, John Kissel K242.
