I can turn off the air suspension and 24 hours later it has not lowered at all. I do the same thing with the trunk switch left on and 24 hours later it has not lowered any. I can not see where I would have that big of a leak for the compressor to come on so often. Does this point to a bad ride sensor? Maybe a bad module? I have read many previous posts, but still not sure. Any help would be appreciated. I do have the factory service manual.
