Stop in for a cup of coffee

I need to work on the heater in my Dakota. It is heating at about half mast. Only about halfway up on the temp gauge. If I remember, a piece of cardboard made it happier. I could pull out the scan tool and check the temp. Probably needs a stat.
The early Daks had shitty heat, cold air would find its way through/around heater box.
Avalanche gets stupid hot inside in this weather.
