AC not working

My air conditioner isn't blowing cold air.
Experienced mechanics share their insights in answering this question :
While there could be a variety of different reasons as to why your air conditioner is not blowing cold in your Mustang as it should be, the most common problem is low refrigerant. Unfortunately just topping off the radiator with more refrigerant will not automatically fix the problem, it is just putting a bandaid on the wound. With A/C concerns, I highly recommend enlisting the assistance of a certified mechanic to come by and inspect your Mustang’s A/C system in person. They will have the experience and tools needed to identify why your AC is not blowing cold air and they will also make the necessary repairs to keep you cool while you drive your Mustang on those hot summer days.

The most common reasons a Ford Mustang ac isn`t working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor. You may not realize there`s a refrigerant leak until the air conditioner stops blowing cold.
Your car`s AC stopped working most likely because of a freon leak or a bad compressor. Though these causes are the simple to spot reasons for your AC not working inside your car, it might be anything as simple as a dirty cabin filter or a bad belt.
Turn the AC dial in your car to the high and low settings to see if the airflow changes like it normally does when it`s operating correctly. If the airflow is adequate, you can rule out issues with the blower motor. If you don`t have any air coming out of the vents, you probably have an issue with your blower motor.
One of the most common reasons your car AC is blowing hot air is because of a refrigerant issue—specifically, a loss of refrigerant. This loss of refrigerant can occur either due to a leak or because your car`s refrigerant levels are too low.
If the clutch doesn`t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. In some vehicles the compressor clutch relay is turned on and off by the low pressure switch and the evaporator temperature sensor.
A typical vehicle will have multiple fuses connected to the operation of the AC unit. To locate the correct AC fuse(s) in your vehicle`s fuse box—and the fuse box itself—refer to your owner`s manual. You can usually tell a fuse is blown if the wire within the fuse is visibly melted or burned.
Look for it first around on the exterior of your machine, especially along the bottom edge near the ground. An AC`s reset button is typically red and visible, so it should be easy to spot. If you don`t see a reset button on the outside, it could be located inside the unit behind the service panel.
On average, the cost for a Ford Mustang Car AC Repair is $249 with $116 for parts and $133 for labor.
Common Reasons AC Doesn`t Run Cold

The most common causes of broken air conditioning leaks or compression issues. If you are feeling cool — but not cold — air, the issue could be a clogged filter, a problem with the cooling fan, signs of radiator trouble, or it could simply mean it`s time to recharge your AC.

Honda Civic 2008. AC stopped working suddenly and engine check light came ON for a day.Next day AC worked and no engine light.
ANSWER : Hi there. In both cases, when an AC system is not working and a warning light is coming on the dashboard, typically a professional mechanic will complete the same initial inspection, which is to download the stored error codes that triggered the warning light initially. This tends to give them an idea as to what is causing the problems. This could be something as simple as an electrical relay that is faulty or loose or an indication of a computer related "glitch". Either way, the best way to move forward is to have a professional mobile mechanic complete a check engine light inspection.

My AC does not always work. If I fiddle with the blower knob I can ususally get it to work on the lowest setting.
ANSWER : Hi There,
It sounds like you may have a faulty blower motor resistor. The highest speed setting may still work because in most cars in the highest fan speed settings the current bypasses the blower motor resistor. In some cars, if the resistor is failed, the fan may stop working completely. Another reason a blower motor resistor may fail is when the blower motor has a mechanical problem or when a foreign object jams the blower motor fan blade and prevents it from spinning freely. This leads to increased current through the resistor and causes it to overheat and fail. I would suggest having an expert from YourMechanic come to your location to diagnose your system to determine what may be causing the fan not to work properly.

My dash board don’t work my front light work when I change my light into high beam and my back window won’t go down
ANSWER : As unfortunate as it is, your vehicle would be considered flood damaged. Diagnosing electrical problems in a flood damaged vehicle is nearly impossible. This would take many hours or even days to determine which wiring harnesses and circuits have been affected. Then nearly all of the wiring under the dash would likely require replacement as well as many sensors and switches. On a BMW vehicle, the amount of wires and switches are likely more than that of a lower end vehicle. Due to the inefficiency in cost, you would likely be able to purchase another BMW like yours for less than what it would cost to fix your car. Many insurance companies would consider this type of damage to total out the vehicle unfortuantely.

My AC is not working took it the mechanic and he told me that’s it has a blown fuse box which is causing my AC not to work?
ANSWER : Hi there. I have not seen a fuse box fail very often on this vehicle. It is possible that he meant to say that the fuse for the AC is blown which makes a lot more sense. Most of the time when the AC fuse blows it is because the compressor is failing and has a short in the clutch.

The circuit is going to have to be tested for a short to confirm why the fuse blew. It can take some time to trace the wires, though it is probably the compressor. If you need to have this diagnosed, consider YourMechanic, as a certified mechanic can come to your home or office to inspect your AC system.

Windshield wipers stopped working. They’ll suddenly stop working then suddenly start working again. Has been happening for a week.
ANSWER : The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring. One, or more, of those electrical components has failed although it is also possible that the mechanical arms are binding (seized, if the lubricant has dried out) thus causing the electric circuit to the motor to overload. Regardless of the underlying fault, if you request a non functioning wiper diagnostic/repair, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

replaced ac relay and recharged ac which worked for a few days. Also can hear clicking from actuator in glove box. Any suggestions
ANSWER : If the A/C system was working properly (producing cold output) and then just "suddenly" stopped, broadly there are two possibilities: 1) you have a leak and consequently the refrigerant level is too low; or 2) the refrigerant charge is undisturbed (no leak) but for some reason the compressor has stopped functioning. If you request an a/c inspection/diagnostic, the bottom line is the responding certified mechanic will get it resolved quickly but here is an indication of some of what’s involved in diagnosing this. Using pressure gauges one first determines if there is any charge at all in the system. If there is a charge, you can attempt to command the compressor on and then see if high and low side pressures look reasonable (in range). If the pressures are good and the compressor does function, you move on to see why the clutch is not engaging when YOU command the A/C on via the switch at the dash. If, however, the mechanic cannot directly activate the clutch and get the compressor to even run, that typically means the compressor clutch is bad. Sometimes the clutch can just be changed on the car, so no big deal and you don’t even have to "open up" the a/c system. Other possibilities include a faulty low or high side safety switch which fault also prevents the compressor from starting. If you request the a/c inspection/diagnostic, the mechanic will resolve this. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

My ac slowly stopped working after just two days.
ANSWER : The air conditioning system relies on a full system charge to function properly. A poorly operating air conditioning system is usually caused by a low charge from a leak. If the air conditioning compressor electronic clutch fails, the fuse blows or the relay burns out, you will notice the lack of cooling. The refrigerant inside the air conditioning system is a gas whose use and handling require a certification. Consider hiring an experienced technician like one from YourMechanic who can come out and give your vehicles air conditioning system a performance check which includes checking system pressures in an effort to offer you a more personal diagnosis.
