Ac problems - AC Cars & Trucks

If you are experiencing AC problems with your 2011 Nissan Juke, there could be various reasons behind the issue. Diagnosing the specific problem will require a closer inspection or assistance from a qualified mechanic. Here are some common AC problems and their possible causes:

1. Weak or Warm Air Flow: If the air coming from the AC vents is weak or not cool enough, it could be due to low refrigerant levels caused by a leak in the AC system. Other possible causes may include a malfunctioning compressor, faulty condenser, or issues with the blower motor.
2. AC Not Blowing Cold Air: This issue could be caused by a refrigerant leak, a malfunctioning compressor, or a faulty expansion valve. Additionally, a clogged or restricted AC condenser could also result in the AC not blowing cold air.
3. Strange Noises from AC: Unusual noises such as grinding, rattling, or hissing sounds coming from the AC system could indicate problems with the compressor, condenser, or blower motor. It's important to have these noises checked promptly to prevent further damage.
4. AC Cycling On and Off: If the AC system frequently turns on and off, it could be due to low refrigerant levels, a faulty pressure switch, or issues with the AC clutch or compressor.
5. Electrical Issues: Problems with the AC system's electrical components, such as fuses, relays, or wiring, can also lead to AC malfunctions.

To diagnose and resolve the AC problem accurately, it's recommended to take your Nissan Juke to a certified mechanic or an authorized Nissan service center. They have the necessary expertise, diagnostic tools, and experience to identify the specific issue and perform the required repairs. Attempting to fix AC problems without proper knowledge and tools can lead to further damage or safety risks.
Remember that regular maintenance and servicing of your vehicle's AC system can help prevent issues and ensure optimal performance. It's a good idea to have your AC system inspected and serviced at recommended intervals to keep it in good working condition.

You can buy fuses in petrol stations. There is more to AC though than just a fuse. There is a relay as well and an electronic clutch.

Car AC stopped working There are several things that can cause electrical problems for your car's air conditioning. These can include failed switches, a blown fuse, a problem with the control module or something else. Fuses can short out and make the A/C stop working or a loose connection can create an electrical short that is easily fixed.Sep. 24, 2019

The major problem with recharging your own ac system is that it needs a leak to require a refill
That leak eventually looses gas and the problem starts again
next thing is that it is not a matter of hooking up the supply and letting in gas as there has to be a set pressure requirement for the volume to be right. Now by what you have done is
not fixed the problem,
need to have the thermostat checked for correct operation
check operation of climate control (if fitted)
remember that more gas does.'t equate to colder air but a properly maintained ac system does.
have the system checked for leaks and operation by an accredited ac specialist shop

the ac blows cold air and if it is not doing that the there is a problem with the ac system,(leaks) or the ac compressor ( belt problem or clutch not getting power)

adding Freon may not be the answer but will cause unnecessary problems if not done by a specialist. Have an accredited ac specialist look at the problem as the ac may not be working because of a leak in the system. He may have also used the power wire for the radio and so there is less current available to work the ac.

The rear defrost is an electric switch for the defroster in the rear glass.
If you turn on the ac and do not get cold air, the first thing to check is if the compressor is running. If not, you could be low on freon or have an electrical problem in the circuit for the ac clutch.
If the compressor is running and one of the ac lines is ice cold, you could have a blend door problem under the dash.

Have a good mechanic to check to see if the door of the a/c and heater and defroster is working properly. I had the same problem and one mechanic said he could fix it for $750. I got it fixed by an honest mechanic for less than $100. Good Luck!!

Hi I just repaired this same problem, It was tough to diagnose. The failed part is the cabin blower motor resistor unit below the glove box. I had ac and recirc lights flickering and the ac compressor going on and off with the flicker.
Hope this helps

Your problem could be caused by MANY things/components. Example, if there is LOW pressure in the AC system, it will not work. Blown AC compressor magnetic clutch fuse, (does this Santa Fe have FULL AUTO AC or Manual?). If the evaporator Thermostatic Switch is malfunctioning, the AC will not work.. if the AC compressor clutch relay is broken, the AC will not work, if the coolant temperature sensor is malfunctioning and telling the ECU (engine control unit) the temp is above 240 degrees, the AC will not work, etc. Here's a first step, go to http://www.hmaservice.com/ and register. You will find gobs and gobs of technical info on your vehicle -- more than you probably want to know.

if the compressor was locked up the drive belt would come of when u engage the AC compressor, your problem is most likely a low charge
