this is the heater control valve.

when you turn the Hot/Cool dial on the climate control, you're basically opening or closing this valve via this cable. when set to hot, it opens the valve and lets hot coolant flow through the heater system inside.
thanks bud. i guess that's where i was leaking coolant from. replaced now.
