Question about 2003 Mercury Grand Marquis
Rear end sagging and compressor runs for 10 seconds but will not lift the rear end of 2003 grand marquis
What is odd is the compressor stopping after so short a time. It may be your only problem.
When you have a leak in the system, the compressor keeps running because the sensors do not signal for it to shut off. On your vehicle it is either being told to shut off prematurely or the compressor is triggering a circuit breaker.
There are ride height sensors on the rear. If the vehicle was lifted without turning off the Air ride, the sensors may have been stretched.
You can check for air leaks in the suspension bags, and air lines using a spray bottle of soapy water. There is also a Master dump valve that should be ahead of the Drivers front tire/radiator well area. It is not a concern unless there is no pressure in the system.
Finally, just as the engine can express diagnostic Codes, so can the suspension. You need a better scanner to do this function. It is the quickest way to find the problem.
Please rate my info.

It sounds to me like your compressor got killed. What probably happened is that the airbag got a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag killed the compressor. I would recommend going to strutmasters.com and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. I added the link below so you can check it out.
I hope I was of some help
