How to identify the external temperature sensor of a Fiat 500 L.

Model: Fiat 500 500 L - Years 2012-2023
Part: Checks and maintenance

Let's see how to replace the external temperature sensor of the Fiat 500. It is a small protrusion located at the bottom of the right side mirror of the car. The YouTuber has removed the cover, and we can see the sensor, which is the black button at the end of the wiring. This sensor is important because the reading it takes of the external temperature affects the operation of the air conditioning or heating. Therefore, we recommend testing the wiring operation with a tester, and possibly changing the sensor, which can be found for example on Amazon with the code B0D5SHR75B for a price of 30.00 euros, with free delivery.

How to Reset the Central Locking of the Volkswagen Golf 4?

If the central locking system of the Volkswagen Golf 4 is not working, it is likely necessary to reset the system: to do this, open the driver's door and detach the side panel of the dashboard next to the steering wheel. Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14. To reset the system, remove this fuse from its housing, then reinsert it or replace it with a new one of the same amperage: this will reset the central locking system.
