My dad's focus had the needle exactly how you describing it. It would be good in the summer, but when it gets colder it would never warm up. Also the air from the vents was warm or more on a cooler side. We suspected the thermostat and replaced it while flushing the coolant system. That fixed the problem. Now the car is nice and toasty when warmed up :))
