A car radio is one of the most important accessories of your car. For those karaoke drives to listening to some serene music, it is one of your essential ride partners. But they can get cranky sometimes and through a tantrum. But mending them is quite easy
If a car radio won’t turn off, basically indicates continuity of the electricity into the system despite being commanded to turn off by the car. The reason can be many as it is related to the electric system of the car and it can be a real pain sometimes to deal with them. This article tries to explain this problem in a simple manner
What Causes Car Radio To Not Turn Off?
Dealing with a car radion wont turn off can be a cat and mouse game as it involves the car electrical system. With this article, I have tried to simplify it by breaking down the problem into common issues that might be causing the radio to not turn off. Some of the common issues are as follows-
1. Shorted Internal Circuit
As the car radio is basically made of these smart integrated circuits, a failure in them can send the whole thing for a toss. Circuit failures can create short circuits which will lead to car radio wont turn off position as a permanent state. When a circuit fails, it can be changed as a separate module or may entail complete system replacement.
2. Dirty Buttons
A dirty environment is the biggest enemy of modern-day electronics. Dirt can lodge itself in the button mechanism of the car radio and as a result, the button won’t follow the command of the user. It will lead to the car radio being in the on position despite telling it to shut down by the user.
3. Electric overload
Sometimes it happens that we get overboard with installing music accessories in the car. I mean who does not like that banging stereo system? But it can cause havoc with the car’s electrical system if you will go beyond the design limits of the car’s electrical system. It can lead to an unintended flow of electricity into the car radio due to a short in the wiring and it can also lead to a fire if not attended to in time.
These days cars, especially German cars, have a lot of brains inside a vehicle in the form of modules. They are generally called comfort modules or body control modules. They control everything right from the small door bulbs to the car’s engine management system. sometimes it happens that moisture enters these modules and then all hell break loose. Since they also control the radio of the car, it can lead them to run or in a permanent state of being on even after turning the car off.
What Are The Symptom Of Car Radio Won’t Turn Off?
A major symptom of car radio won’t turn off is the draining of the car battery. If your car battery is draining of frequently in the span of two or three days, then chances are that the radio is sucking off all the juice while the car is still turned off. Another thing is that the car radio might continue to glow even after turning off the car or it might continue to play music through the speaker even after turning it off.
How To Fix Car Radio That Won’t Turn Off?
Fixing a broken car radio can be a very simple task to a complete replacement of the device itself. Since the causes are many, I have tried to narrow down basic solutions that can be helpful for a car radio won’t turn off situation. It can be a DIY activity or if you are not electrically inclined then you have to seek professional help. Some of the common fixes are-
1. Electric Contact Cleaner
The buttons of the car radion can gunk up with dirt and oil and as a result, they just quit responding to the user commands. Giving a nice spray of contact cleaner can really clean them up and make them work like they are new. Caution must be taken while using it. The electric system must be shut down and windows must be rolled down as these sprays are a fire hazard.
2. IC Repair
If the internal circuit of the car radio has an internal shot, then it can be repaired very easily. These days, car manufacturers even supply child parts where an independent module can be replaced very easily in a plug-and-play fashion. Getting them repaired however can be a complicated task in some high-end cars and in the worst case, a replacement is in the cards.
3. Car Wiring Repair
A bad car wiring can cause the car radio wont turn off state as a short in the wiring can still keep the power going on in the system. The good news is that repairing them is easy but it involves a lot of labor hours and sometimes it can drain a good amount of money out of pocket to repair.
4. Replacing The System
Unfortunately, some of the high-end cars are so complex and precisely engineered that their components cannot be repaired sometimes. So the best bet is to replace the whole system instead of repairing them, as the cost of repair will usually in these cases surpass the replacement cost. The good news is that it can be a good opportunity to finally upgrade your music system to a more modern one.
