Evaporator temperature sensor replacement

The evaporator temperature sensor is an element of the vehicle's electrical air conditioning system. The sensor is installed on the air conditioner, determines the air temperature behind the evaporator and serves to prevent freezing of the evaporator during long-term operation of the air conditioner. The signal from this sensor turns the air conditioning compressor on or off when necessary.

Signs of a faulty evaporator sensor.

Freezing of hoses.
Spontaneous switching off and switching on of the compressor.
The air conditioner does not work, there is no cold air.
Air conditioning adjustment does not work.

In this case, contact a car service to diagnose the problem. If it turns out that your temperature sensor on the air conditioner evaporator is not working, you just need to replace it. It is better to replace the sensor in a specialized car service, since when performing work on replacing the sensor, certain knowledge, skills and abilities are required, and a special tool is also required.

The main stages of work on replacing the evaporator sensor

Diagnostics of the electrical system of the car.
Installation of the sensor on a car may vary slightly depending on the model, but as a rule it is located in the area of the stove behind the instrument panel. It may be necessary to remove the protective parts of the instrument panel to gain access to the sensor.
Work must be performed with the battery disconnected.
Dismantling the sensor, having first disconnected the sensor power connector.
Installation of a new sensor.
Diagnostics of the air conditioner.
Installation of protective elements.

Proper operation of your car's air conditioner will provide you with a good mood and comfortable driving...

AC Blowing Hot Air

The air conditioner is blowing hot air because of sensor issues in the evaporator and ambient air temperatures. However, it can also be a failure in the blend door motor, compressor relay, or HVAC(Heating, Ventilation, and Air Conditioning) control head.

Is your car feeling more like a sauna? If so, don't sweat it - try to find out what's wrong first. Plus, when your car air conditioner system starts blowing warm air, it's essential to address it immediately. Not only can a malfunctioning AC be a real drag on your comfort, but it can also be a safety hazard if unchecked.

Don't let the situation get any hotter than it needs to be. Instead, ensure your vehicle stays in peak condition, keeping you cool and collected on the road. Remember - a minor issue can quickly snowball into a major headache if left unaddressed. So, avoid future troubles and enjoy a worry-free ride by investigating earlier.

AC Only Work Sometimes

It’s only working sometimes because the cabin air filter is too dirty, the “mode” door motor is faulty, or the variable compressor is stuck. Alternatively, the following parts might intermittently malfunction: the ac control unit, the ac high-pressure switch, and the evaporator temperature sensor.

Are you experiencing an unpredictable AC system in your car? One moment, it's working fine, and the next, it's not cooling at all? Air conditioners that blow cold air at one time and warm air at another are probably going through electrical issues.

Don't take this issue lightly! Ignoring it could put your safety at risk and lead to costly repairs. Instead, consider discussing with a professional to address the problem immediately.

Doing so ensures your vehicle remains in good working order, and you can drive it carefree, knowing your car air conditioner functions consistently. Don't let a minor AC issue become a significant problem that could have been avoided with timely maintenance.
