Okay, I might be getting a handle on this - a little. Still need someone to tell me if I'm right.
I think the picture shows the ELC compressor, and thanks to another thread (ELC questions!!
), I understand it a little better. Right now, my very heavy tool box is sitting in the trunk on that side. So it sounds like the compressor is kicking in because of the added load. I just never noticed it before, and I don't know what a properly functioning ELC compressor sounds like.
I'm also wondering if it'* functioning correctly because I have no idea how long I've been driving with the rotted vacuum lines and what kind of effect it may have had. Guess I should check the other side, too.
Should the compressor kick in every time I start the engine as long as I have the extra load? In my case, it does. But it seems like once the height adjustment is made, it should stay put until the load changes. Yes? No?
BTW, the vehicle has 120k miles. Don't know if that'* a red flag for certain ELC components or not.
Any advice will be greatly appreciated.
