The PO had put a ball valve in-line for the incoming hot water to the heater core. I'm not sure why he would of done this, and it has always been closed. Is it bad to not have water running through there? I'm tempted to open it, but I'm a little nervous about hot water pouring into the cab. There must of been a reason he would have done this..... Any ideas? The original heater controls were broken, and I just got a new heater control for Christmas and installed it, and since the weather has been a little cool (for Florida standards) I wanted to have everything operable. Here's a pic to show where the ball valve is:
