    Hyundai ix35 AC Compressor Faults: A Guide by Keepin Cool Auto Air Conditioning

    When it comes to vehicle comfort, a well-functioning car air conditioning system can be a lifesaver, especially in the heat of an Australian summer. However, like any component in a car, the AC system, particularly the AC compressor, can run into issues. Today, we’re focusing on Hyundai ix35 AC Compressor Faults – a prevalent issue that Keepin Cool Auto Air Conditioning is quite familiar with.

    Understanding the Role of the AC Compressor in Your Hyundai ix35

    The heart of your car’s air conditioning system is the AC compressor. This vital component:

    • Takes in low pressure, low-temperature refrigerant gas.
    • Compresses the gas, increasing its temperature and pressure.
    • Sends the high-pressure gas to the condenser where it is cooled and changes back into a high-pressure liquid.


    Common Hyundai ix35 AC Compressor Faults

    Just like a human heart, when the AC compressor fails, the entire AC system falters. Below are some common Hyundai ix35 AC Compressor Faults that you, as a vehicle owner, should be aware of.

    1. Leaking Refrigerant

    If your Hyundai ix35’s air conditioning isn’t cooling as it should, a leaking refrigerant could be the main culprit. Given the high pressure within the compressor, it is prone to leaks over time.

    2. Strange Noises

    Squealing, ticking, or grinding noises are often early warning signs of compressor problems in your Hyundai ix35. The presence of such noises warrants an immediate mobile car AC service.

    3. Locked or Seized Compressor

    Due to internal component wear and lack of lubrication, a compressor may seize up or lock, leading to complete AC failure.

    Troubleshooting Tips for Your Hyundai ix35 AC Compressor

    Have you recently noticed that your Hyundai ix35 air conditioning isn’t as cold as it used to be, or that the AC system pressures on the high and/or low sides are abnormal? If so, you may want to perform a diagnostic check on your variable displacement AC compressor. Here’s a step-by-step guide crafted by Keepin Cool Auto Air Conditioning, your Brisbane car air conditioning specialists.

    Checking the AC System

    1. Initiate the process by starting the car’s engine. Set your blower speed at level 2 and then toggle the AC to MAX, ensuring the temperature is set to the lowest level.
    2. Proceed to check the AC pressure. The high-side pressure must register above 130 PSI.
    3. If the high-side pressure is below this specification, check the built-in torque limiter slip clutch of the compressor pulley. This slip clutch prevents AC drive belt disengagement in case the compressor seizes. If the compressor does seize, the clutch shears off engagement points, allowing the compressor pulley to rotate freely without applying rotational force to the compressor input shaft.

    Diagnosing a Sheared Torque Limiter Slip Clutch

    While the engine operates normally, observe the centre bolt of the pulley. It should rotate at the same rate as the pulley itself. If only the pulley is spinning while the centre bolt is stationary, it’s an indication that the torque limiter slip clutch has sheared due to internal binding. In this case, compressor replacement becomes unavoidable.

    When the centre bolt is rotating as expected, continue with the following diagnostic procedures.

    Testing the External Control Valve (ECV) Resistance

    With a diagnosis kit, connect a multimeter to the leads from the ECV. The ECV resistance should ideally range around 10.1 ~ 11.1Ω at room temperature (25°C) but may change due to higher underhood temperatures. The acceptable range for resistance is between 8 and 14 Ω. If the resistance falls outside this range, you’ll need to change the ECV.

    Testing AC Pressure

    Using a test kit, gauge the AC pressures while the engine idles, the blower at speed 2 and the AC set to MAX. Your low-side should read 20 – 40psi, while your high-side should be between 130 – 190psi.

    If the AC pressures appear normal, check the wiring to the AC heater control head and repair any wiring/connection issues. If pressures remain outside the specified range despite the wiring being faultless, consider these steps:

    • Verify whether the radiator cooling fans are working properly.
    • Empty the system and refill with the correct refrigerant charge.
    • Check for blockages in the AC lines, expansion valve, evaporator or condenser fins.
    • Inspect the ECV valve for any corrosion, damage or bent pins.

    Finally, if there are still problems and you couldn’t find any other faults, consider replacing the ECV.
