I have a 2000 Park Avenue Ultra that I bought for my wife. Lately the rear end bounces like it has no shocks on it. I have been told that there is some kind of air pump that controls the shocks. I have looked under the car and I can see the air lines similar to the ones I had on my 1969 roadrunner back in the early 70's. My question is, how do I go about trouble shooting this problem. I have been told to look from anything like a fuse to a crimped airline. But I need a starting place.

Thanks, Jim
