Yesterday I noticed that all of a sudden the rear suspension on my Buick LeSabre was too stiff and very rough going down the road. I believe that my rear shocks are filled with too much air. What would cause the compressor to all of a sudden fill the shocks up with too much air? What would be the problem here?

If it's below freezing the pump air exhaust may be frozen and has no way of leveling. If you can get it in a warm garage or the temperature changes it will melt and start working normally. The pump may have a short, online videos for the repair. The wiring harness has a short. The level control is bad or has a short.

Here's addtional information and the fuses to check.

The Factory Service Manual has trouble trees for problems with the ALC. Is the back of the car too high?
