FX3 ride control
 

Just bought a 1993 C4. On start the Service Ride Control light DOES NOT come on. The ride control switch makes no difference in ride and it is a very hard ride. We have inspected the Bilstein Shocks appear to be good no leaks but very firm pushing down on frame. I have checked the ride control module behind the seat and nothing is disconnected. any thoughts or help would be appreciated.
