Question about 1996 Mercury Grand Marquis
What has probably happened is you got a hole or cracks in your airbag. Dealerships and mechanics typically diagnoses it as the compressor but that is only to keep you coming back and wasting more money on something that will never truly be fixed. Both the airbag and the compressor are the problem. The compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag will kill 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. This is a PERMANENT fix. I added the link below so you can check it out.
I hope I was of some help

Nine times out of ten it is the rear air spring leaking. With the car raised on a hoist and the air suspension switch off the air bags should hold pressure. Then spray them with soapy water and look for bubbles. You can also remove the air spring and pressurize it in a tank of water to expand it for a more thorough test but can be a little tricky. Often times the springs(bags) will leak only under certain loads. I believe that the replacement spring will come with a new solonoid. If not you should replace it anyway. If the air spring is ok you should check the ride heighth sensor on that side. A false signal could force the module to release the air.
