We at Certified Tire & Service in Utah can take care of your AC compressor as well as the rest of your vehicle's air conditioning system. Because of this, the AC compressor as well as its components can wear out and even fail over time. When your vehicle is running with the central air conditioning on, the AC compressor is constantly working to compress and circulate the air conditioner refrigerant. How do I know if my AC Compressor needs repairs? Having a clutch prevents the AC compressor for having to work all the time rather, it is only engaged when your air conditioning is on and you desire cool air. The AC compressor runs when the pulley is engaged to the compressor driving shaft. Your vehicle's air conditioner compressor also has an electromagnetic clutch that engages and disengages the compressor pulley. To make sure all parts of your air conditioning system are working appropriately and you drive a Ford, Dodge, Chevrolet, GMC, or any other make, you can bring your car to Certified Tire & Service today. Once the water is removed, the refrigerant can start the cycle all over again. This is achieved by a component known as a receiver or dryer. Before the refrigerant can cycle back through the system, any water that may have been created in the process needs to be removed.
It is located in front of your vehicle's radiator so it is exposed to more air that flows through your car. The AC compressor is a long tube that goes back and forth through several cooling fins. The compressor is known as the power unit of the air conditioning system that moves refrigerant, or coolant, around the pipe and puts the liquid under high pressure before it is pumped into the condenser. In case these methods fail to rectify the problem, it is time to take your car to the mechanic.Your vehicle's air conditioning system has many parts that remove heat from the warm air entering its system. If they are fine and still the AC is not working, then the electric clutch is bad and needs to be replaced. If you hear a ‘cluck’ sound, then the clutch is fine and other wires and fuses have to be checked. Unplug the connector in that wire and connect the wire to the positive pole of the car battery. Compressors have a wire leading to the electric clutch. Another possible reason can be bad wiring. This is easy to fix and can be done by you. Step 5 - Other Common ProblemsĪt times, the belt of the fan (attached to the compressor and another in front of radiator) could be snapped and so the auto air conditioner might not be working. Check for any of these conditions, fix it and then re-check the compressor again. If it is not working, then the possible reasons could be blown fuse, broken wires, switch problems or low level of refrigerants.
Locate the compressor and check if it is running (it produces a humming noise). To identify the problem, start the car and turn on the AC. In most of the cases, problems with compressor result in inefficient auto air conditioner. Step 4 – Compressor ProblemsĬompressor is the heart of an auto air conditioning system. Clean the condenser with duster to restore the cooling capacity. Step 3 – Clogged CondenserĬheck for the status of the condenser, if it is clogged then the cooling fan closer to it cannot turn on thereby reducing the cooling effect. Thus, it is recommended to get the optimum pressure of Freon restored locally from a qualified technician. Due to environmental issues and strict federal laws governing them, only a qualified technician can refill Freon. If any one of the measures is below normal, then Freon 134A has to be refilled. To check the level and pressure of Freon, attach the pressure gauge to the compressor hose, start the AC system and take the readings. It is a combination of gas and liquid that is compressed and circulated for cooling the air. Step 2 – Level of Refrigerantsįreon is used as refrigerant in the auto air conditioning system. If there is a leakage, the dye will make it apparent and then you can get it fixed by a qualified technician or do it yourself. Wait for few minutes and check for coloring in the coils.
Add the fluorescent dye to the system and turn on the AC.
