Where is the a/c compressor cycling switch located

probably overcharged the system and now the high pressure switch is stopping the ac from working
did you fix the leak first

The low pressure switch (also known as the AC compressor switch) will be under the hood, it will be located in the low side AC line from the AC compressor, this is the larger of the two lines from the AC compressor. See picture below, looks like it has a three wire connector. Also what is the AC doing that makes you think this switch is defective? Cycling on and off constantly?

a/c cycling switch bad. probably located in the compressor itself, but possibly remotely located usually on the reciever/drier

Should have a high pressure switch and a low pressure switch in the line or on the compressor.

If the freon is full and at correct pressure, then have the switch located on a/c compressor tested. Had the same problem and it was the switch on compressor.

does the compressor run when bypass the compressor thermal cutout switch on the compressor? here is the part number and a picture.
also does it run when u bypass/jump the compressor cycling switch? it is located in the low side of the sytem, thios is the line that is the larger of the two, hwere is the part # and picture.

1. compressure cutout switch (3 diff ones used)
FOUR SEASONS Part # 35756
Compressor Mounted Cut-Out Switch; 1 Term White
type two
FOUR SEASONS Part # 35973
Compressor Mounted Cut-Out Switch; 2 Term; Blue or Green; Low Pressure
type 3
FOUR SEASONS Part # 35970
Compressor Mounted Cut-Out Switch; 2 Term; Yellow

this is type one and two, two wires.

next is type 3 one wire.
Next is the low side compressor cycling switch, most common problem.

ACDELCO Part # 155606 {#96069320}
SWITCH,A/C CYCLING

On this Chrysler product they have an A/C Transducer located on the high pressure hose. The switch has three wires. They also have a thermo sensor located at the evaporator case behind the glove compartment. These two things are the only ones thatA jump in the system is only removing protection the system has. So it will damage your compressor or hoses. Find the compressor follow the high hose to the high pressure switch (transducer) it has three wires. Check under the dash by the glove box and you will see a round platick lid on the case with two wires that is your thermostat (thermo sensor).
control the compressor.

The A/C clutch is controlled by the A/C cycling switch (19E561) and the A/C pressure cut-off switch, which are connected in series. The A/C cycling switch is mounted on the suction accumulator/drier (19C836), and the A/C pressure cut-off switch is mounted in the discharge line at the A/C condenser.

The A/C cycling switch closes when the pressure on the low side of the system reaches approximately 276-324 kPa (40-47 psi). The A/C cycling switch opens when the pressure drops to approximately 163-175 kPa (23.5-25.5 psi), disengaging the A/C clutch. In ambient temperatures below -1° C (30° F), the A/C cycling switch will not allow compressor operation because of low system pressures.

The A/C pressure cut-off switch is used to interrupt A/C clutch operation in the event of high system discharge pressures. The A/C pressure cut-off switch is a single-function switch that controls A/C clutch engagement. When compressor head pressures rise to approximately 2896 kPa (420 psi), the contacts open, disengaging the A/C clutch. When the pressures drop to approximately 1724 kPa (250 psi), the contacts close to allow A/C clutch operation.

This problem can be caused by low refrigerant charge. Check with a manifold gauge set and temperature pressure chart.
The cycling switch is replaceable and there is a Schrader valve on the accumulator port so you do not lose your system charge when replacing. It screws on/off. It is available at any auto parts store. It protects the compressor from low pressure which can be caused by a loss of refrigerant and subsequent lack of lubrication and prevents evaporator freeze up. Replace the switch. It is about $10. The high presure switch is about $25.

if you are looking for the cycling switch, it is located at the pass rear of engine compartment at air box on top of accumulator if you are looking for the high pressure switch it is located at the compressor in the line

there is a thermistor switch located in evaporator case(thin black single or 2 wires) that makes the compressor cut in and out (cycle) it monitors evaporator temperature.
check head pressures with air cond charging station or gauge set and monitor pressure on high and low side (150-200kpa on low, 1500-1800kpa on high good average depending on ambient temp) if it is low on gas due to leak this can also keep compressor running longer due to evaporator temp not reaching lowest threshhold to cut compressor out

by pass the cycling switch located on a/c acumulator and turn a/c on if works then you might be low in freon or have a bad cycling switch
