Re: Need more heat in Esteem
What does the temp gauge show during these times?
Does it sit at the half way mark between hot and cold (normal) or does it never move above the cold mark (not normal)?
If the temp gauge is in it's normal operating range (halfway), then the heater core is not getting coolant flow or the temp door (inside under the dash) is not closing properly. Also, the cooling system could be low on coolant.
If the temp gauge stays at the cold mark, then the thermostat is staying open.
Good luck!
