Air suspension solenoid valve block is an electronically-controlled module that's used in air suspension systems to fill and vent each air bag. It is responsible for distributing air from the compressor to air struts or air springs. Over time its O-rings can dry rot, causing damage to the compressor via air leaks and overworking, along with moisture damage to the electrical solenoid components.
The main problem with the valve block is that the solenoid valves may leak air back to the compressor or the central air reservoir. This can cause the vehicle to not maintain the ride height required. If you need help with troubleshooting the valve assembly, you can replace a new valve bolck. It is located near the air suspension compressor and easy for replacement.
