Why is there a burning smell when turning on the heater?
1 Answers
There may be a burning smell when turning on the heater due to aging air conditioning wiring, heated components, or blocked air vents. Aging air conditioning wiring: The air conditioning wiring may have aged, or the heating element may be malfunctioning, causing it to overheat. Heated components: There are many plastic and rubber components in the engine compartment. When the engine temperature rises, these plastic components may heat up and emit a burning smell. Blocked air vents: Blocked air vents prevent hot air from entering the cabin, causing the plastic inside the air conditioning system to overheat and emit a burning smell.
