Why is my car air conditioner cycling on and off?
I turned the A/C off and stopped putting R-134a into it becuase the compressor cycling was almost causing the car to die from the load it was putting on the engine. Onto Google I went. Everywhere I turned, people said that if the compressor was cycling on and off quickly, that meant the compressor was low on freon.
What happens if the clutch on the AC fails?
No cooling at all In more severe cases, where the switch has completely failed, your AC system will completely cease to blow cold air. Without the cycling switch to activate the compressor’s clutch, the AC system will not be pressurized correctly, and the system will be unable to produce any cold air as a result.
Is it normal for car AC compressor to cycle on and off?
Since the mid-1990s, most cars equipped with air conditioning have also been outfitted with electronic modules that tell your car’s AC compressor to cycle on and off. Although it may be alarming the first time it happens at a stoplight or when you are idling at the store, it is very normal.
When does the air conditioner cycle on and off?
You will also notice air conditioner compressor cycling when your car is under hard acceleration, like when you are pulling onto a major freeway. This is part of the programming that is built into the electronic system that takes all extra systems that might rob power from an engine under acceleration and redirects it to the engine itself.

Why does my a / C turn on and off?
So problem fixed. Took about 10oz. of freon and a new A/C actuator. Now looks like it might need a new A/C and heater control since it kicks on the compressor when the knob is turned to defrost and it stops blowing hot air to the windshield.
Why is my air conditioner not cooling down?
A problem our technicians often address in air conditioning systems is short-cycling. This is when an air conditioner becomes trapped in the start-up cycle so it doesn’t complete a regular cycle. The thermostat activates the compressor to begin cooling down the house, but for some reason, the compressor shuts down early.
What causes an air conditioner to short cycle?
Air conditioner short cycling occurs when something within the system prevents your unit from completing a full cooling cycle. A full cooling cycle occurs from the time that the unit kicks on to the time that the temperature you set at the thermostat is reached and the unit kicks back off again.
Why is my car a / C not blowing cold air?
If your car’s A/C isn’t blowing cold air, you could be looking at anything from a leaking hose to a faulty evaporator core. Diagnosing the root cause of A/C problems in your vehicle can be difficult since there are so many possibilities.
