Where is the air ride switch located in a 2000 Ford Explorer?

A 2000 Ford Explorer did not come standard with an air ride suspension system. Air ride suspension was not a factory option on that model year. Therefore, there is no air ride switch. If you have an air suspension system, it's an aftermarket addition, and the switch location would depend entirely on where the installer placed it. Check under the dash, in the center console, or even possibly near the air compressor itself.
