I guess I'm not explaining very well.
The cable that should open the valve lets in hot water is not hooked up at the valve. It is hooked up at the control panel on the warm/cool lever.
I've looked at the box a couple times and I dont see where the other end goes so I'm assuming that I have to remove it to gain access in order to rehook.
In short: cable is attached at control lever, other end is laying in the floorboard.

Thanks for the help. I hope this clears it up a little.
