Hey everyone. I have a Taurus that has a heating problem in the winter time. Last winter when the temp was at or below 32 degrees the car would never heat up. I changed the thermostat but no change. Temp gauge would show about 1/4 operating temp at idle but when I go down the road, it starts heading down, colder, almost like I never crank the car. Water pump seems to work ok, no problem in the summertime with over heating. When the outside temp gets warmer, the inside will warm up. Any ideas? Thanks in advance
