The centre part of the solenoid you have shown is electrically operated and works with a magnetic shaft that pulls in and allows the air pressure to continue throttle the valve it's either seized or not working at all strip and inspect this piece first.
Hey where exactly is that valve located? You said under the car...is it under the passenger side by rear door....I see a protection panel that can come down...just dont want to take it down if thats not the location
supaaaafly Bad height sensor? Ok how did you determine that after all of your trouble shooting? I have replace the ECM and the EAS Control Unit still nothing..... I'm knee deep in now so....Height Sensor sure I will try it😀
Where is that valve located on your vehicle and that’s all you did was just changed out height sensor and your rocker lights come back on? Thank you sir
Jeffrey Harvey reset your car disconnect battery next check for holes in air suspension next learn how to reset air suspension. Check your air suspension fuses .
