It's called short cycling. The most common cause is low freon. Take it to a mechanic for diagnosis.
The AC clutch is on the front of the compressor where the belt rides. When power is applied to the clutch it engages to turn the compressor. It is basically a magnet a/c compressor clutch is the ound thing on the front of the compressor with pulley wheel attached. this clutch is an electro magnetic clutch that when electricity is supplied, engages so as the a/c compressor is driven ,which can then pump freon thru the ac system
The A/C compressor is clutch driven, when electricity is applied to a coil, it engages the clutch. Most likely the coil shorted out in the A/C clutch on the front of the compressor.
Bad A/C compressor clutch. Bad A/C compressor clutch.
The A/C Compressor may not be charged with frion if the A/C Clutch does engage, or it may not engage due to fact it's not sending 12v to the electronic wiring. First start the engine and turn on the A/C, watch if the clutch on the compressor engages or not.
The A/C compressor puts an extra load on the engine when it engages. This is most likely the engine hesitation you are experiencing.
Engages and disengages the compressor clutch as needed.
Vehicle could have a solenoid type switch to increase idle to compensate for load on engine caused by A/C compressor
How Much Does Car A/C Compressor Repair and Replacement Cost? Car a/c compressor replacement costs about $994 for a car a/c compressor with average prices of a car a/c compressor ranging from $842 for a compressor to $1146 for a car a/c compressor in the US for 2020, according to Repairpal
Check your battery... The A/C Compressor is probably bad. I had the same problem and when you turn on the ac it engages a clutch that is driven by your fan belt and if the compressor is bad it will stop the belt from turning and stall the engine. The same thing will happen for a bad alternator.
The Air conditioning compressor is likely seized. There is a clutch in the pulley that engages the compressor when the A/C is turned on. You can easily check the compressor (with engine off make sure the pulley has had time to cool off as it will be very hot) Try to turn the most center part of the pulley. If you cannot turn it by hand the compressor is seized. The smoke was MOST likely from the serpentine belt rubbing on the seized pulley when the A/C compressor was engaged. Please note that the same belt drives the power steering pump. This belt will be destroyed from the heat and must be replaced to prevent a possible steering failure.
It might be that the A/C compressor isn't engaging when it is turned on? While the engine is running and while looking into the engine compartment at the compressor, have someone turn the A/C to the 'on' position and watch to see if the compressor actually engages or not. You ought to actually be able to hear an audible 'click,' and there will be a slight but noticeable change in the engine speed when it does. If not, then you might have a blown fuse or electric relay, or even a loose wire connection. It's also possible the that compressor may have failed.
Which Compressor are you talking about ? The a/c compressor or the rear suspention Compressor ?
