Reasons for HVAC Blower Failure in Your BMW
Something that sets BMW vehicles apart from other luxury brands is the features that they offer for comfort, including an enhanced air-conditioning system. The HVAC system allows for optimal climate control at all times so that you can stay cool no matter how hot the day is outside.
Unfortunately, the HVAC blower sometimes fails, leaving drivers uncomfortably warm on those sunny summer drives. This system, like any other, needs regular maintenance and care to stay in good condition. When this is neglected or the HVAC blower fails, you need to get it fixed as soon as possible. You paid the premium; you deserve all that a BMW offers. In this article, we are going to talk about the warning signs of HVAC blower failure, why it fails, and what you can do about it.
Warning Signs of HVAC Blower Failure
When you see a technician for repairs, you should be able to accurately describe the symptoms of the problem you are experiencing if you want the quickest, most efficient care. Notify your technician if the air flow is weak or inconsistent. If you turn on your BMW’s air conditioner and later, you do not notice any temperature difference, put your hand up to the vents. If the air is blowing weakly, this is likely a problem with the HVAC blower. However, if no air is coming out at all, this is not a sign of blower failure, but rather an electrical problem. It is vital to differentiate between the two.
This is really the only main issue you can diagnose by yourself. If the air never gets cooler when you need it to, this is also not likely due to an issue with the HVAC blower. Instead, your BMW may be leaking freon.
Why HVAC Blower Failure Happens
Your BMW’s HVAC blower is probably failing or malfunctioning for one of two reasons:
- The blower motor relay is not working as it should. The blower itself needs electricity to make air flow through the vents into your car. When the motor does not run, the air does not flow. Think of it the same way you would a speedboat. When the motor does not run, the boat won’t move forward.
- Normal wear and tear could simply be the cause of blower failure. As every vehicle ages and the parts are used consistently, they break down. In most cases, these parts can be repaired or replaced. If your blower malfunctions, it is just a sign that you need regular maintenance.
What You Can Do for your HVAC Blower
In the future, you can exercise some control over how often a part fails in your BMW. You do this by scheduling regular maintenance services and inspections with a qualified auto technician. They can detect damage before you do in many incidents and give you repairs before you end up taking the bus to work.
For now, all you can do is see that professional for HVAC blower repairs. Going to a mechanic who works on mainly domestic brands may not be wise because they may not get the job done right initially. A dealership will certainly put your wallet on a diet.
