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.

These guys are amazing I booked an appointment with them for a different date, but they texted me saying we have the parts and can come over the same day in the evening and can do the service. They are that fast and reliable service I ever seen. The mechanic who came over for the service is real good, I feel bad about not have the space he need to do the service as I don’t have the drive way so need to park in parking spaces which I have. But the mechanic took the challenge and did it anyway, sorry guys.

The mechanic was at my place two hours ahead of schedule and did a great job. This is a very convenient service and the quality of the work is the same as in a auto service.

This is by far and away the best experience I’ve had with any mechanic. They arrived early, got the job done fast and even explained what they were doing so I could get a better understanding of my vehicle. Not to mention the fact that they were lower in cost than the quotes I received from other companies. The service and convenience just can’t be beat.

10/10! Scheduling was easy, pricing wasn’t too bad, and the mechanics they sent out were to the point and fast. I will definitely be using them in the future.

Requested a quote on Yelp for mechanics that could let me know what was causing my check engine light to come on. Instant Car Fix was quick and painless to get a quote and have someone come out same day! The mechanic David met me, conducted the diagnostics and gave me great information as well as followed up for possible other solutions. Would definitely recommend the company and David! Will be a repeat customer!

I was out of town, in a pinch, and all of the other shops had been booked up. Instant Car Fix gave me a quick call back with a plan of action and quote. I put the car in a nice quiet place and they saved me. I was able to meet my deadline and get back on the road for my next appointment in Pennsylvania that night. Instant Car Fix was very professional and recommend them in a pinch. ++ !
