1999 Buick Park Avenue Question: Auto ride level

 

Question

The auto level system has the back end of my car lifted to the highest level. I have disconected the level adjustment lever and I can hear the compressor run when I manually move the lever. It is as though the system will not bleed off excess air. How can this problem be fixed?

    It is common for the pressure release valve to fail. The valve is part of the compressor cylinder head assembly. There is a cylinder head replacemant kit available so that you don't have to replace the complete compressor. In order to be sure the release valve is at fault you will need a wiring digram which you can use to confirm that the proper signal is being sent to the release valve from the height sensor.
