- The blower motor is a small motor that regulates the blowing capacities of your automobile's heating and cooling system. The VDO Siemens model is dark gray and shaped somewhat like a wheel. In the center is a metal connection rod used to fasten the engine into place under the car's hood. The device is a small, but important part of your vehicle's total system.
- The blower motor is most often found under the instrument panel of the car, once you've opened up the hood of the vehicle. You must disconnect the old motor and remove the retaining screws one at a time. The retainer clip can be taken off by hand and saved or discarded. Afterwards, you should be able to extract the motor with the accompanying wheel and install the new device in the same manner the old one was installed.
- The blower motor, in large part, is responsible for the functioning of your heating and cooling system in your car. To be precise, the blower doesn't create the cold or hot air, it just distributes it throughout the cabin. Without a working blower motor, the car may overheat as it tries to push more cold or hot air out. If the air isn't being distributed by the motor, most of it will simply not make it into the cabin of the vehicle.
- The price range varies with this product depending on whether you purchase a new or used motor. As with any car part, it's best to purchase the newer option. However, slightly used or new PM247s are often available on eBay or Amazon. A new one should cost about $50, while used ones cost anywhere from $20 to $30 (as of August 2011) or even less.
