Your vehicle’s temperature blend door is the part that is responsible for passing air over the heater when you have the heat on in your vehicle, or passing that air over the cooler when the air conditioning is on. If the blend door isn’t working, then you’re going to have a difficult time staying comfortable while driving your car, and things could get potentially dangerous in especially hot or cold weather.
If the blend door malfunctions or breaks, then you’re going to have a number of problems to deal with in your vehicle. Here are just a few examples of some of the most common signs of blend door failures in Madison, TN:
- Defrost issues: If you’ve got the defroster turned on but it takes quite a while before you actually see any results, this is a sign that you could be dealing with some blend door issues. You might not even see the windshield defrost at all, or it will remain perpetually foggy. You’ll need to see an auto service specialist when these issues arise.
- Strange noises: In some cases, you may have the defroster turned on and the air comes out at an extremely fast pace, regardless of the setting. When this happens, you might also hear a strange grinding or clicking noise, which indicates parts inside the blend door are scraping against each other. It might sound like a sharp rap or knock. This will be most noticeable right as you turn on the heating or cooling system or the defroster.
- Setting issues: If you have different quantities or temperatures of air coming out of the driver and passenger side vents than what you expect based on the settings you’ve chosen for your air conditioning or heating, this is also a sign that you’ve got something wrong with your blend doors that needs to be repaired.
There are a variety of potential causes for these issues. The components used to control the blend doors are electric, and there is an entire calibration process that must occur within the system to determine the level at which the heat or air conditioning should be working. Occasionally this process of repeated calibration can result in the plastic doors bending and breaking over time. This calibration process happens when the car turns on, so the more frequently you drive, the more likely this is to be an issue.
The good news is that this isn’t an extremely difficult issue to fix, but it can take some time to figure out that this is the problem you’re dealing with, meaning you could potentially mess with a different part of your vehicle before tackling what’s actually wrong with it. This is one of the biggest reasons why it’s so important to bring your vehicle to a certified auto service specialist rather than trying to deal with the problem yourself.
