What To Do With A Hyundai Veloster AC Knob Not Working

When something in your car is not working as it should, it can most certainly be an inconvenience. Whether it is just a small component or something major, you definitely would not want to deal with any issue with your vehicle.

This is why if you have noticed you have an issue with your Hyundai Veloster AC knob not working, then you may want to do something about it. Otherwise, this prevents you from adjusting the temperature in your vehicle, which can cause some discomfort for you.

With this in mind, let us take a look at some problems that can happen with your AC knob and what to do about it.

For instance, there are those who have experienced the control knob breaking off while in the midst of adjusting their vehicle’s air conditioning. If the weather outside is warm and you have a cool vehicle – then there should not be any worries. However, this is not the case if the vehicle feels much cooler than how you want it. 

So, if you want to fix your knob, you should first check if the rod connected to it has any damage. Perhaps the rod is broken or detached, which would need more repair work done. But if there is no damage at all, you can simply snap the knob back into its place and it should be all good.

On the other hand, a broken knob would definitely need to be replaced. If the rod is still intact, you only need to buy a replacement knob to get this issue fixed. But if you notice that the rod is broken, then you will have to take your vehicle to the dealership. Keep in mind that it does not suffice to install a new one since this will not solve the issue.

There is a high possibility that there are more damages involved with your AC knob, which a simple installation of a new knob cannot fix. For instance, it may be possible that more intensive repair work is needed. There are cases when a complete removal of your dashboard will be required to fix this issue.

So, it is best to have a mechanic take a look at the problem to get professional advice for your situation.

Now, there are also some concerns about the AC switch acting up. The knob, even after adjusting, is unable to control the fan well. When turning the knob, the speed of the fan simply goes low or the regular temperature is blown out. The knob has become delicate, which makes it different to adjust the temperature.

With that being said, you need to check with your dealer since there may have been a recall on your vehicle model, specifically for its knob. Otherwise, you may have to replace your AC assembly, or even perhaps cleaning the contacts on this component can work.

Additional Points About The Hyundai Veloster AC Knob Not Working

If you notice that your AC knob is not working, perhaps it is unable to turn, or when you do get it to turn, there may be a piece of plastic that comes off, which makes the knob defective. It may even turn freely, yet unable to change your AC settings. 

In this case, it could simply be a knob issue. You may be able to use your pliers in rotating the metal component where your knob is connected to. Then, you can purchase a replacement knob or hot glue your old one back into place. But when doing the latter, you need to make sure that it is pointed in the right position. 

It is also worth checking if this issue happens all the time or when you accelerate only. If you have an air distribution system that is vacuum operated, then it is highly likely that you have a vacuum leak going on. However, if you have an electronic AC, then it could be that your air blend motor is simply failing.

There are some drivers who encounter this same issue with their AC knob, and after taking their vehicle to the mechanic, they were not able to get a definitive answer. First, they were told that it would be necessary to disconnect the terminals of the battery and hold these terminals for about 30 seconds.

This will then discharge the car’s capacitors and let the systems undergo a reset. But if you have to do this, you will need to take your keys with you since the door may lock up and not be able to access your vehicle.

Some people who did this system reset were able to have the issue fixed. While there may not be any guarantee that it can work for all, it is most certainly worth a try. The only thing you need to do after this task is to reset your radio and clock presets.

Additionally, you will have to remove your switch and check your connector on the back portion of your switch. If you notice some burnt wires at your switch or connector, then it means the problem is electronic. Switches are prone to burning out, which means you will have to get it replaced.
