Car heaters themselves don’t produce carbon monoxide (CO). However, if there’s an issue with the exhaust system, such as a leak or a malfunctioning catalytic converter, CO from the engine’s exhaust could potentially enter the car’s cabin, especially if the heater is running. It’s essential to ensure your car’s exhaust system is in good condition and to never run the engine in a closed space, like a garage, to prevent carbon monoxide poisoning.

A certain level of noise is normal for a car’s heater system, especially when it’s operating at higher settings. However, if you notice unusually loud or abnormal noises coming from your heater, such as rattling, squealing, or grinding sounds, it could indicate a problem with the blower motor, fan, or other components. In such cases, it’s advisable to have your vehicle inspected by a qualified mechanic to diagnose and address any issues before they worsen.

Yes, blower motors can often be repaired. However, the feasibility of repair depends on the specific issue causing the malfunction. In some cases, simple repairs such as replacing a worn-out bearing or a faulty electrical component can restore the blower motor to proper functioning. However, in other cases, if the motor itself is severely damaged or if it’s more cost-effective to replace the entire unit, then replacement might be recommended.

It’s essential to have a qualified mechanic diagnose the problem with the blower motor to determine the best course of action. They can assess whether a repair is feasible and cost-effective compared to a replacement.

Yes, carbon monoxide (CO) can potentially enter a car’s cabin through the vents if there’s a leak or malfunction in the exhaust system. The exhaust system of a car is designed to safely remove harmful gases, including carbon monoxide, from the engine and expel them outside the vehicle. However, if there’s a leak or damage to the exhaust system, such as a cracked pipe or a faulty catalytic converter, CO can seep into the cabin, especially when the ventilation system is active.

It’s crucial to ensure that your vehicle’s exhaust system is regularly inspected and properly maintained to prevent carbon monoxide from entering the cabin. Additionally, never run the engine in an enclosed space, such as a garage, as this can lead to a dangerous buildup of carbon monoxide.
