When energized, the solenoid opens to allow fluid to drain back to the reservoir; when de-energized, it closes to maintain system pressure. It is commonly replaced when the valve leaks, the coil fails, or the liftgate operates slowly or erratically. The AMF3330 is a complete assembly (valve body AMF3338 and coil AMF3345) that serves as a direct aftermarket replacement for several OEM drain valves.
