2007 International pro star Suspension dump switch flashing

1st mine does that from time to time. When it does I just flip it to dump and back, it stops flashing...

The other thing is the electric controller may be bad... it's on the inside of the frame (driver side).2 relays (1 to dump & 1 to fill) side by side... 1 may be bad... the 2 in the middle control the levering valve

 

It will flash when the computer is detecting an electrical problem with the wiring or solenoid packs. Like mentioned above, it is common for the connection between the solenoids and the pack base to become corroded and cause problems like this.

 

I have 2006 international I have a similar problem the suspension only dum but is not going up not how you mentioned probably is because bed relay ore bed solenoid were I find the relay on the 2006 intert
