The Mk6 version of the Volkswagen Golf is unfortunately remembered for its heater issues. When faced with a lack of heat, the first step is to check your coolant level, as insufficient fluid can lead to heater problems. This simple solution is crucial because ignoring it can have serious consequences. If the coolant level is not the issue, the problem could lie with a faulty heater core, heater resistor, thermostat, blower motor, or blower motor core. The complexity and cost of replacing each of these components can vary, so it's important to accurately diagnose the problem before attempting any repairs. Keep in mind that fixing a Volkswagen is generally not cheap, with some parts being significantly more expensive than others.
