Initial Checks
Experiencing problems with your Volvo XC90 driver side AC can be frustrating. Before contacting a professional, start with some initial checks. These simple steps might save you time and money. Let’s go through the basics to ensure your AC starts cooling again.
Check Settings
Begin by checking the AC settings. Ensure the AC is set to the correct mode. Set it to “cool” and adjust the temperature to the lowest setting. Make sure the fan speed is not set to zero. Verify if the air recirculation button is turned on. This helps the AC cool more efficiently.
Inspect Vents
Next, inspect the vents. Open each vent fully. Ensure no objects are blocking the airflow. Sometimes, dust and debris can clog the vents. Use a soft brush or vacuum to clean them. This can improve air circulation and cooling.
Fuses And Relays
The Volvo XC90’s driver side AC not working can be frustrating. Often, the problem stems from issues with fuses and relays. These components are crucial for the AC system to function properly. Let’s dive into how you can check and address these issues.
Locate Fuse Box
First, you need to locate the fuse box. In the Volvo XC90, the fuse box is usually found under the dashboard on the driver’s side. It may also be in the engine compartment. Check your owner’s manual for the exact location.
Once you find the fuse box, open it carefully. You will see a diagram on the cover or in the manual. This diagram shows which fuse controls the AC system. Make sure you understand the layout before proceeding.
Test Fuses
Now it’s time to test the fuses. Use a fuse tester or a multimeter to check each fuse. Pull out the fuse related to the AC system. Look for a broken wire inside the fuse. A broken wire means the fuse is blown and needs replacing.
If the fuse looks fine, test it with the multimeter. Set the multimeter to the continuity setting. Touch the probes to the fuse terminals. If the multimeter beeps, the fuse is good. If not, replace the fuse.
After replacing a blown fuse, check if the AC works. If the problem persists, the issue might be with the relay.
Relays are also located in the fuse box. Use your owner’s manual to identify the correct relay. Swap it with a similar working relay from another system, like the headlights. If the AC starts working, the relay was faulty. Replace the bad relay to fix the problem.
Blower Motor Issues
Experiencing issues with the driver side AC of your Volvo XC90 can be frustrating. One common problem involves the blower motor. This component plays a crucial role in ensuring your AC system functions properly. If it malfunctions, the driver side AC may stop working. Let’s dive into how motor function and wiring inspection can help diagnose and fix this issue.
Motor Function
The blower motor is responsible for pushing air through the vents. If the motor is faulty, it won’t blow air as needed. This can make the driver side AC stop working. To check if the motor is the problem, listen for unusual noises. Grinding or clicking sounds can indicate motor issues. Also, check if the motor is running at all. If it’s completely silent, the motor might be dead.
Wiring Inspection
Wiring issues can also cause blower motor problems. Damaged wires can prevent the motor from getting power. This will stop it from working correctly. Inspect the wiring for any visible damage. Look for frayed wires or loose connections. These can interrupt the power supply to the motor. Fixing or replacing damaged wires can solve the problem.
Refrigerant Levels
Experiencing issues with the AC on the driver’s side of your Volvo XC90? One common cause could be the refrigerant levels. Proper refrigerant levels are crucial for the AC system to function efficiently. Low levels can lead to uneven cooling or complete AC failure on one side. Here’s how you can check and recharge the refrigerant levels to restore optimal performance.
Check Levels
The first step is to check the refrigerant levels. You can do this by using an AC gauge set. Attach the gauge to the low-pressure port of the AC system. This port is usually located near the firewall or on the compressor. The gauge will give you a reading of the refrigerant levels. Compare the reading with the recommended levels in your owner’s manual.
Low refrigerant levels indicate a leak or normal wear. In either case, recharging the system will be necessary. But make sure to check for any visible leaks before proceeding with the recharge. This will prevent future issues.
Recharging System
To recharge the system, you’ll need a refrigerant recharge kit. These kits are available at most auto parts stores. Attach the kit to the low-pressure port. Follow the instructions on the kit to add refrigerant. It’s important to add the refrigerant slowly and check the pressure frequently. Overcharging can damage the AC system.
Once you’ve added the proper amount of refrigerant, disconnect the kit. Run the AC for a few minutes to ensure it’s working properly. Check the temperature of the air coming from the vents. If it’s cool and consistent, the recharge was successful.
If the driver’s side AC still isn’t working, there may be another issue. It could be a faulty compressor, a blocked condenser, or an electrical problem. In such cases, professional diagnosis may be required.

Temperature Sensors
Temperature sensors play a critical role in the functioning of your Volvo XC90’s air conditioning system. These small, yet essential components monitor the temperature inside and outside your car. They help in regulating the climate control system, ensuring a comfortable ride. When the driver side AC stops working, faulty temperature sensors might be the culprit.
Locate Sensors
First, you need to find the temperature sensors in your Volvo XC90. The sensors are usually located around the dashboard area. Check both the driver and passenger sides. You can also find them near the evaporator and heater core. Consult your vehicle’s manual for exact locations.
Sensor Testing
To test the sensors, you will need a multimeter. Set the multimeter to measure resistance. Disconnect the sensor from its connector. Place the multimeter probes on the sensor terminals. Compare the reading to the values specified in your car’s manual. If the readings differ, the sensor might be faulty. Replace it to restore proper AC function.
Ac Compressor
The AC compressor is essential for the air conditioning system in your Volvo XC90. It keeps the air cool by compressing and circulating the refrigerant. If the driver side AC is not working, the compressor might be the issue.
Compressor Operation
The AC compressor starts by taking in low-pressure gas from the evaporator. It then compresses this gas, turning it into high-pressure gas. This high-pressure gas moves to the condenser, where it cools down and turns into liquid. The liquid refrigerant then flows through the system, absorbing heat and providing cool air inside the car.
If the compressor fails, the refrigerant cannot circulate properly. This results in warm air blowing from the vents. Understanding how the compressor operates can help diagnose and fix the problem.
Diagnose Problems
Diagnosing the AC compressor involves a few steps:
- Check if the compressor clutch engages when the AC is turned on.
- Listen for unusual noises from the compressor.
- Look for any visible leaks around the compressor.
- Use a pressure gauge to check the refrigerant levels.
If the clutch does not engage, the issue might be electrical. If there are leaks, the refrigerant might be low. Unusual noises often indicate internal damage. Using a pressure gauge helps confirm if the refrigerant levels are adequate. Addressing these issues can restore the AC functionality on the driver side of your Volvo XC90.
