A friend has a '58 Cad and needs assistance with his original equipment air suspension. It goes up when you put it into that mode - for wheel changing etc, and goes down to the ground nearly. But doesn't sit at ride height. He also has a slightly leaky air bag which he knows he has to replace (where from?)
What should he check first? Is there a ride height sensor system etc? How does this system work? Any tips, pointers and systematic diagnosis checks would be greatfully recieved and I'll pass them on. I did recommend he join up here and post.
thanks all! Nick
