Is your vehicle’s blowers only blowing on one setting?

Are the heater blowers only blowing hot or cold? Is only one vent blowing air? Is there a strange noise or burning smell? Autoexperts Medway can test heater resistors in Gillingham in Medway.

Ventilation System Explained:

Modern cars are designed to have a constant through-flow of fresh air that keeps the interior atmosphere pleasant even with all the windows shut. The incoming cold air can be heated by the engine to keep the windows clear of mist and the car interior at a chosen temperature.
Air enters a large duct at the front of the car commonly through grilles in the scuttle panel. They are placed so that when the car is moving air is forced in through the air vents. From there it goes to the Heater, which warms it if required.

How it works:

The incoming air can be heated as it enters the cabin. It does this by allowing air to pass though the fins of a mini radiator or Heater Matrix. This is normally situated in a heater box behind the dash board.
Air blowers then blow the air through the front foot-wells and through vents on the dashboard. By changing the position of flaps and vents, they can be adjusted to point at the windscreen, the side windows or alternatively at the faces of the front-seat occupants.

The Resistor:

The air blowers switch runs through a resistor which alters the power to the blowers. A resistor restricts the power running through the heaters electrical system. When you turn the blower switch up the resistors resistance lessens allowing more power to pass through to the blower motor causing the fan to spin faster.
At the rear there are exit vents to the outside. When the car is moving these vents allow air to pass through giving a constant through-flow.

Common Faults:

The most common fault with regards heating blower systems is the blowers stop working on all the different settings. This is normally due to the resistor burning out. Another common fault can be wiring to either the resistor or blower motor. They can become warm and over time cause a poor connection. In extreme circumstances this can cause a burning smell and will require early investigation to rectify any potential fire hazard from occurring.
