Have you fixed your heater problem? How do you fixed? I think if your temperature gauge goes down you may still having problems with your heater.
I think heater was not working because the heater control valve is blocking water circulation thru the heater radiator or because for some other reason the water is cold.
If your heater works fine on city but not on highway and your temperature gauge goes down to cold when you press the gas in high idle it seems like you are running without thermostat.
