Where is the temperature sensor of the Bora evaporator located?
2 Answers
The evaporator temperature sensor of the Bora is installed on the evaporator, near the wiper. The air conditioning temperature sensor is located inside the air box, on the air conditioning evaporator. The function of the evaporator temperature sensor is to sense the temperature of the evaporator and regulate the operating time of the air conditioning system. Here is more information about the evaporator: 1. The evaporator temperature sensor serves to protect the air conditioning system, preventing frost formation on the evaporator surface, which could reduce heat exchange efficiency. Generally, a surface temperature of the evaporator around 2-4 degrees Celsius is considered the frost formation temperature, and this feedback is sent to the AC switch to control its operation. 2. The relationship between the evaporator temperature sensor and the AC switch is a NAND gate, meaning both signals must meet the requirements for the air conditioning to activate, and then it is connected in series to the high and low pressure switches.
The temperature sensor for the Bora's evaporator is located inside the center console, right next to the evaporator. You'll need to remove the glove box and some plastic trim panels underneath to see it. Last time I worked on an old Bora, I ran into issues with this part—the A/C cooling was intermittent, and after testing, it turned out the sensor data was drifting. To replace the sensor, you first need to disconnect the A/C lines, being careful not to let refrigerant leak everywhere. Then, use a hex key to remove the mounting screws—it's a tight spot, hard to get your hands in. Don't forget to apply some refrigerant oil to the seal when installing the new sensor, or it might leak later. The whole job takes half a day if you're doing it alone. If you're not confident in your skills, it's better to let a professional auto repair shop handle it—much less hassle.
