Mercury Grand Marquis rear axle air bags not holding air, seeking repair solutions on Mercury Grand Marquis

Some Mercury Grand Marquis owners report experiencing issues with rear axle air bags not holding air, which can be caused by several factors. These owners often find leaks in the air bags that need to be thoroughly inspected to identify the source of the problem. In cases where the air bags are damaged or worn out, replacing them with new air springs is a common solution to restore proper air retention. Additionally, some owners have reported that inspecting the compressor and solenoid valves is crucial, as these components are essential for maintaining air pressure in the system. Others have attempted to jump the relay pins to directly power the compressor, testing its functionality. In some instances, a temporary repair to the existing compressor assembly has provided a short-term fix until a permanent solution can be implemented. Addressing these issues promptly is important to restore the functionality of the air suspension system.
