My Air suspension light keeps coming on my 04 crown Victoria, what is the problem

The suspension system will need to be professionally diagnosed. This is not an easy system to work with, but a trained technician with proper equipment can find the source of the problem. One or both of your air springs could be leaking air. Your lines could be leaking. The dryer may be leaking. The compressor may not be turning on. The compressor relay may not work. The height sensors could have issues, the solenoids could have issues. The control module could be in question. Wiring could be a concern. Testing is needed.

I have a few friends that had this system on their cars and they got tired of spending money on it and bought the conversion kits,no more problems. Ford Crown Victoria Suspension Conversion Kits — CARiD.com https://www.carid.com › ... › Suspension Systems › Suspension Conversion Kits › Ford
