I am having problems with my heater. It seems to work fine in the city on but within 5-10 minutes of being on the freeway my temperature gauge goes down and it starts blowing cold air. Any known causes?

If the temperature gauge drops, it's not a heater problem. The engine coolant isn't staying hot enough. Suspect the thermostat is sticking open and must be replaced.
