Hi Michael. Thanks for contacting us today. Usually, this type of issue (when the heater isn’t working well and temperature issues) is caused by an obstruction of debris inside the heater core. Coolant flows through the heater core to supply the heat (as the engine temperature increases). If there is debris trapped in the heater core, these type of issues can occur. If the debris is not removed, or the heater core replaced - it can lead to serious overheating issues.
