      Four common causes for an AC blowing hot air in the vehicle and their related parts.
      This fix will help eliminating

      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 HVACHeating Ventilation and Air Conditioning control head Is your car feeling more like a sauna If so dont sweat it try to find out whats wrong first Plus when your car air conditioner system starts blowing warm air its essential to address it immediately Not only can a malfunctioning AC be a real drag on your...

      Symptoms of a bad evaporator temperature sensor

      A bad evaporator sensor typically causes your vehicle's air conditioner to stop working, freeze too much, or blow warm air. The evaporator temperature sensor tells your vehicle's brain (the computer) to either drop or increase the temperature to dodge a freeze-up; it acts like a thermometer to prevent things from getting too cold or hot inside, protecting wires, circuits, etc. The evaporator temperature sensor sits behind your dashboard, near the glove box.

      1. Inconsistent or Weak Air Conditioning (A/C) Performance

      A faulty evaporator temperature sensor can cause the air conditioning system to behave erratically. Since this sensor monitors the temperature of the evaporator to prevent freezing, a malfunctioning sensor might give incorrect readings, causing the A/C to cycle on and off too frequently or not blow cold air at all. This results in fluctuating cabin temperatures and an uncomfortable ride.

      2. A/C Compressor Not Engaging or Staying On Too Long

      If the sensor incorrectly detects that the evaporator is too cold, it may send signals to shut off the A/C compressor prematurely, preventing the system from cooling properly. On the other hand, if the sensor fails to detect freezing temperatures, the compressor might stay on too long, which can lead to an overworked system, increased wear, and potential damage to other A/C components.

      3. Ice Buildup on the Evaporator Coils

      A defective evaporator temperature sensor might fail to detect when the evaporator is too cold, allowing moisture to freeze on the coils. Over time, this ice buildup can block airflow, reducing the effectiveness of the A/C and causing the system to struggle to cool the cabin. If ice forms, you may notice weaker airflow or even a complete loss of cold air until the ice melts.

      4. Warm Air Instead of Cold Air

      If the sensor incorrectly tells the A/C system that the evaporator is already cold when it isn’t, the system may stop cooling even when you need it. This can result in warm air coming from the vents even though the A/C is turned on.

      5. Increased Cabin Humidity

      The evaporator helps remove moisture from the air before it enters the cabin. If the sensor malfunctions and prevents the A/C from functioning correctly, it can lead to higher humidity levels inside the vehicle, making the air feel damp and uncomfortable.

      6. A/C System Stays Off or Fails to Turn On

      In some cases, a completely failed evaporator temperature sensor may prevent the A/C system from turning on at all. This happens because the climate control system relies on this sensor to regulate cooling operation, and without a proper reading, it may default to a fail-safe mode, shutting down the system entirely.

      7. Check Engine Light or A/C Warning Light

      On some vehicles, a failing evaporator temperature sensor can trigger the Check Engine Light (CEL) or an A/C system warning light. If the vehicle’s onboard computer detects incorrect temperature readings or a failure in the sensor circuit, it may store a trouble code, which can be retrieved using a diagnostic scan tool.
