2012 Volkswagen Passat Blower Motor Repair in Downtown Portland

I’ve heard that rodents love this thing. Is that true?

There have been cases where rodents have made their home near this motor. It does tend to get warm near this part because of the heater core which is what they like. However, that is fairly uncommon but it does happen. There are pictures of other people who have had this happen to their vehicle but it is not a 100% chance that you will have it happen to you. Obviously, it depends on where you live and what the weather is doing.

Ok, that’s weird. What does this thing do anyway?

The blower motor does what you probably think it does. It takes cold or warm air and pushes the air through your vents to accommodate your climate settings.

Where is this usually located in a vehicle?

It is usually found near the heating ventilation and air conditioning ducts, also known as HVAC ducts. A lot of vehicles have this space behind the glove box.

I’m curious as to how the blower motor gets the hot or cool air. It seems like it should only blow room temperature air out or air that is about the same temperature as it is outside the vehicle. How does this work?

If you ask your Passat for cool air then it blows the air past cold evaporator into your vents. If you ask the vehicle for warm air then the blower motor blows air across the hot heater core and then through your vents.

If I drive this thing in bad shape then it is not going to break my Passat, right? I mean, it has to be running off electricity and, therefore, has the potential of breaking my system, right?

The blower motor should not damage any other systems if you choose to drive with it broken. However, it may not be comfortable because you will not be able to control the temperature inside your vehicle without the use of this part.

Well, could you help me out by telling me what to expect if my blower motor is not doing what it used to be able to do? What would I notice if it was going bad?

The first thing to know is that a blower motor can fail and the heat or ac might still work. You might be able to feel hot or cold air at your vents but they will not have much air pressure. The fan speed and/or temperature will not matter at all. You probably will notice the change in air pressure if your motor is bad or failing.

Is there a time frame that I should look at to determine when I should change my blower motor?

If you drive a lot and have high a lot of miles on your vehicle then you might start thinking about having your blower motor looked at in order to determine the health of the part. If you have had the Passat for a while then you also might want to check the plastic fan blades to make sure that they are still in place and have not broken off. The fact is that the material of the fan blades become weaker and weaker over time and use. They can break off and cause problems. You might also start to notice noises from the passenger floorboards when you use your A/C or heater. The noises could be caused by fan blades that are no longer in good repair or even a faulty bearing. Fan speed usually will not matter.
