The Toyota Corolla is renowned for its reliability and durability, but like any modern car, its technological components can occasionally run into issues.
One of the most reported problems is the touch screen not functioning as expected. If you’re facing this issue, you’re not alone. Let’s look at some of the most common causes and possible solutions.
Common Causes of Toyota Corolla Touch Screen Failure
| Cause | Symptoms | Solutions |
|---|---|---|
| Cold Weather | Screen unresponsive on cold days | Allow interior to warm up, rub screen to generate heat |
| Blown Fuse | Screen totally unresponsive | Check and replace touch screen fuse |
| Software Issue | Screen turns on/off intermittently | Install latest software updates, contact Toyota if issue persists |
| Digitizer Malfunction | Screen doesn’t respond to touch | Contact repair specialist, dealership if under warranty |
Toyota Corolla Touch Screen Not Working Causes
1. Temperature Issues
Cold Weather Impact on Touch Screens
If you’re trying to use your Toyota Corolla’s touch screen on a particularly cold morning and find it unresponsive, don’t panic. Touch screens often operate through heat sensitivity. When it’s cold outside, the screen may need some time to warm up and function normally.
What You Can Do:
- Wait a few minutes with the car running to allow the interior to warm up.
- Try using your fingers to gently rub the screen, generating heat through friction.
2. Electrical Issues
Blown Fuse Can Be the Culprit
A non-functioning screen can sometimes be traced back to a blown fuse. The fuse box for the Toyota Corolla is generally located to the left of the steering wheel.
Steps to Check and Replace the Fuse:
- Look for a small seam or crack along the dash near the steering wheel.
- Use a screwdriver or pry bar to carefully pop open this section.
- Inside, you’ll find an array of fuses. Each one is responsible for a different part of your car’s electronics.
- Refer to the diagram on the back of the panel you just opened or consult the vehicle’s owner’s manual to identify the correct fuse for the touch screen.
- Once identified, pull out the fuse and inspect it. A functioning fuse will have a thin strip of metal connecting the two ends. If it’s broken, the fuse needs to be replaced.
- If you need to purchase a new fuse, they’re relatively inexpensive, often around $10.
3. Screen Display Issues
Intermittent Functioning: On and Off Issues
Some Toyota Corolla owners, like Lekna, have reported their touch screen turning on and off every few minutes. This can be incredibly frustrating, especially if the car is relatively new.
Possible Solutions:
- Ensure all software updates for the vehicle have been installed.
- If the issue persists, it may be a manufacturer’s defect, and you should contact your dealership or Toyota’s customer service for further assistance.
4. Digitizer Malfunction
When The Screen Doesn’t Respond to Touch
The digitizer is the component that translates your touch into a command the car’s system can understand. If it’s not working, the screen won’t respond to your touch even if it’s displaying correctly. Thomas Dean suggests checking the face ID, typically a 5-6 number on the display bezel.
What You Can Do:
- Contact companies like Original Car Audio, as mentioned by Dean. They specialize in repairing such issues.
- If your Corolla is still under warranty, consider reaching out to your local dealership for repair or replacement options.
Conclusion
While the Toyota Corolla is a dependable vehicle, no car is immune to occasional technological glitches.
If your touch screen isn’t working, take a systematic approach to diagnose the issue, starting with the simplest solutions like warming the car or checking the fuse.
Always refer to the owner’s manual for guidance, and when in doubt, seek professional help. Your Corolla’s touch screen is an essential feature, and with the right approach, you can get it back to working condition in no time.
