Those two things are not related. There is a failure in the system, most likely from a seized or inoperative compressor. Unfortunately Ford does a very poor job of making specialty parts available for more than three to five years, but no manufacturer supplies parts for a 20-year-old car. The aftermarket industry has developed a retrofit kit that involves installing regular coil springs to restore the ride height. You won't have the self-leveling feature, but the ride quality will be the same as what you had before.
The front will also have to be converted to coil springs if you don't have them already. If those are replaced, that will put the suspension's ride height back to factory specs, which is the optimum setting for best tire wear, BUT, the car will have to be aligned afterward to insure those adjustments are correct.
