International Lonestar Dump Switch Blinking Fast

Hi there,

My suspension air dump system stopped working and I checked the solenoids and noticed there was oxidation on terminals of both solenoids and in the module. So I replaced the module and the two solenoids that control the air suspension dump system. And it still did not work.

My air horn, that has its solenoid connected to the same module is functioning properly.

The switch on the inside is blinking fast green light.It is not dumping air. Air bags stay inflated. When I unplugged the air line on the solenoid side, no air came out.

I am hoping if someone can help me diagnose this issue.

Thank you in advance.
