Ok, the switch is a four button. Being top left 2 hi bottom left auto 4x4, top right four high, bottom right four low. There is a neutral indicator on the left side of the switch also but no buton.

As for what you asked, when I cycle the key. Neu. Indicator is lit and red, and all the others come on yellow, stay on for a second then all but the four high indicator go out. The four high indicator stays lit, if I try to select another button it blinks a few times then four high stays lit and the other goes out. As for the fuse it was the one that said T CASE that was blown. Again thank you Jim for your expertise and your time, Sincerely Big Todd
