    sounds dumb, and im sure you already have, but make sure the coolant is full in the radiator. air pockets often dont get hot enough to trip the switch even when the engine is hot.

    I'm suzcen. SpasticZ400 is my username there. Did you check your fuse. It's a sure fire fix in most cases. It's on the right side of the radiator.
