Why does my AC not work when idling?
If you find yourself idling without proper cooling after a particularly windy day, it could indicate damage to the air conditioning system. A halt in cooling while idling can possibly be due to a blown fuse or broken fans caused by the debris strike.
What causes car AC to suddenly stop 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.
What can cause AC compressor to not engage?
One of the reasons why compressors do not engage is because of a low pressure lockout, a poor ground, a bad clutch coil, an opening in the wire to the clutch coil, or simply a blown fuse. There are several ways A/C compressor clutches receive power.
Can a blown fuse cause ac not to work?
First of all, your electrical system might be having problems. While this prevents serious trouble such as electrical fires, it also means that a single blown fuse can cause the entire air conditioner to stop working.
How do I know if my ac fuse is blown?
Test the load: If you saw a voltage reading during the previous step, run the same test on the “load” side of the fuses. You should again see a reading between 220 and 240. If you see a voltage reading on the “line” side but not the “load” side, it means you have a blown fuse.
Why is my Nissan Altima AC not working in the water?
Clutch Cycling Switch – A/C systems use an electromagnetic clutch to activate the compressor. When this switch fails your air conditioning is dead in the water. Blower Motor – If there is no air blowing from your Altima at all, the blower motor is at fault.
What to do if your air conditioning compressor is not working?
If the clutch doesn’t engage, the air conditioning compressor can’t pump refrigerant. So start your diagnosis by determining if the compressor clutch works. Turn the air conditioning controls to MAX AC and start the engine. Then look at the front of the compressor clutch.
Does the air conditioner control the heater in a Nissan Altima?
The only thing that the air conditioning system has in common with the heater is that they both use the climate controls and the blower motor. It is entirely possible for your Altima’s heater to work just fine even when the air conditioner is not blowing cold at all.
What happens if the air conditioner compressor clutch is bad?
The compressor clutch also keeps the air conditioning from running constantly. If it ran all the time, you would notice a decrease in fuel economy and have worn-out air conditioning components more often. It would also cause excessive strain on the engine.
