The A/C (Air/Conditionig) low pressure service connector, (low valve), is placed on the input compressor aluminium pipe, near A/C compressor.

Wht is a TXV


Simply it's a valve in a refrigeration system that controls or meters how much coolant is allowed into the evaporator.
A thermal expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant flow into the evaporator thereby controlling the superheating at the outlet of the evaporator. Thermal expansion valves are often referred to generically as "metering devices".
A thermal expansion valve is a key element to a heat pump; the cycle that makes air conditioning, or air cooling, possible. A basic refrigeration cycle consists of four major elements, a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air conditioning occurs. The cycle starts when refrigerant enters the compressor in a low pressure, low temperature, gaseous form. The refrigerant is compressed by the compressor to a high pressure-and-temperature gaseous state. The high pressure-and-temperature gas then enters the condenser. The condenser precipitates the high pressure-and-temperature gas to a high pressure liquid by transferring heat to a lower temperature medium, usually ambient air. The high pressure liquid then enters the expansion valve where the TX valve allows a portion of the refrigerant to enter the evaporator. In order for the higher temperature fluid to cool, the flow must be limited into the evaporator to keep the pressure low and allow expansion back into the gas phase. The TXV has sensing bulbs connected to the suction line of the refrigerant piping. The sensing bulbs give temperature readings to the TXV to adjust flow of refrigerant.[2]

if the compressor kicks on then it may not need gas, you may have another problem, caution dont blow up can or system, if the can is connected to low side and the compressor is running then it should take the freon.

Cant find the valve to refill air conditioning where is it?


Servicing Port will be located along the low / suction hose of A/C between the compressor and condenser. The larger hose is the low side.

Its easiest to follow the larger hose from the compressor to the condenser to find it.

Some models even have the port mounted to the compressor or condenser.

Hope this helps...

Where is the air conditioning low pressure value located?


Its between the compressor and condensor. It looks like a valve on a tire. find the two steel lines running from your compressor. The low pressure side is the bigger line. There should even be a threaded cap on the valve that has an L on it, designating it the low pressure valve...I'm assuming you're charging the ac?

The low and high side valves are located under the air filterbox, if you open the hood and remove the air filter box you will see the valves ,good day

In order to charge, you must locate the low pressure valve to install the refrigerant. The low pressure valve is between the compressor and the evaporator. Do not charge on the High Pressure side, The high pressure valve is between the compressor and the condenser. To locate the low pressure valve, follow the line that comes from the compressor and routes toward the firewall. The valve will be somewhere on that line. Do not overcharge. The amount of pressure that is needed on the low pressure side will depend on the ambient outside temperature.

Why is the ac air conditioning not cooling


Could be low on freon, could be a bad compressor, could be a bad expansion valve, could be..... Get it checked out to find out for sure.
