2002 753 auxiliary button on dash

[safechoice]

Hello, I have a 2002 753 machine I had it in for repairs on the auxiliary hydraulics and they found a bad controller, all fixed. I worked the machine all day yesterday with no issues, came home to unload it and I cannot get the green lights to come on to activate the variable flow or Maximum flow hydraulics on the dash Any suggestions? Can the switch be replaced in the left side dash or is it a complete unit? I did not see a bad fuse, there is one marked "attachments" I am guessing that would be the one. When this button is pushed is it turning on a separate pump or just sending power thru the computer?

Left panel is a complete unit and switch can not be replaced. I wonder if it is a wiring issue at the controller. Its possible the other controller was not bad rather a wiring issue that temporarily started working after they messed with the plugs and wires?
