    Worked last year, suddenly now, hook it up to 3 different trucks, doesnt light up or operate.. Tried cleaning out the connector that plugs into near the dash... on the controller side, no help. Anything internal i can open it and check or is it just a circuit board and fried?

    Open it up and check the on/off switch for continuity through it and be sure the wires aren't pulled off the board. Anything more than that it needs parts or replaced entirely.
