Re: 99 Montana Load Leveling Module
Did you try the self-diagnosis function? Look under the Olds Silhouette forum under "Air Shock Problem", and you'll see the procedure. It works on my 2003, but not sure about the 1999.....I'd be curious to know if it has the diagnosis feature. The fellow I'm trying to help there can't seem to get it to work on his 1998....Glen
