AC Is Not Working Diagnosis

 

If your car's AC is not working, diagnosing the issue can involve multiple steps. It may be useful to have some basic knowledge about the system before attempting to diagnose it. Here are some general steps to follow:

Check for leaks: To ensure your AC is in good condition, inspect its components such as the compressor, hoses, and condenser for any visible damage. Additionally, examine the fittings and connections for any leaks.

Check the pressure: To determine if there is an issue with the AC system, please check the high and low side pressure using an AC gauge. If the pressure is too high or too low, it may indicate a problem with the system.

Check the compressor: Please ensure that the compressor is working properly by listening to any unusual noises when the AC system is turned on. Also, verify that the clutch is engaging correctly since the compressor is the core of the AC system.

Check the blower motor: It's like the engine of your car's air conditioning system, responsible for pushing air into the cabin. Listen closely for any strange sounds when you turn on the AC, and make sure that the airflow increases as you adjust the fan speed. Peek under the hood and inspect the motor's wires and the motor itself for any visible damage or signs of wear. Remember, if the blower motor isn't working correctly, it could seriously affect how well your AC cools the car.

Check the refrigerant levels: To determine if there is a leak or problem with the system, check the refrigerant level using a refrigerant gauge. If the level is insufficient, it may indicate an issue.

Check the electrical system: Please inspect the AC electrical system by examining the fuses, relays, and wiring to ensure that they are all functioning properly.

Check the cabin air filter: It is recommended to inspect the cabin air filter because if it is dirty, it may impede airflow and decrease the effectiveness of the AC system.

It is recommended to take your car to a qualified mechanic or AC specialist for diagnosis and repair if you are not comfortable performing these steps yourself.

My Jaguar battery was dead and I had no way of accessing it since it is located in the trunk….and I could not open the trunk since the battery was dead😵‍💫. Contacted Instant Car Fix and a mechanic was dispatched with a new battery. He was great! Got the trunk opened by jumping a terminal under the hood. Installed the new battery and the car was good to go! Great service by an experienced mechanic! Thanks!

Carl did an amazing job fixing my van. I’m back on the road. Having car trouble is one of the worst inconveniences. I appreciate his services so much.

Mechanic did a great job and showed up with a good attitude. Although there was a complication with the coolant service due to a part that leaked, the rest of the visit went very well. He seemed very knowledgeable and recommended shops that might carry the part I need - being a Euro car there are no local shops that carry parts for my car. Definitely looking forward to working with this company again in the near future when I get the part in.
