Ok. Here'* an update on this problem. I had my wife drive the car today and I followed her and watched the rear suspension. Everytime she hit a bump, the right rear tire would bounce up and down, like it had a bad shock. After we got back home, I removed the right rear tire and checked all the air lines that run from the pump to the shocks. No problems there.
I then disconnected the level sensor from the linkage rod on the left side and within a few seconds, the pump would kick in and start filling the shocks. So, the system is apperently working, but the car still seems to have a bad right shock.
My question is, if the shocks are filled with air, how can one be bad????
