You can see on the VIN number where the jeep was made, but it probably even doesnt matter.

Re: AC Compressor Does't start WJ 02

The assembly plant is shown with the VIN position number 11: a C stands for Jefferson North and an Y for Chrysler Steyer (Austria)
But also the 5th letter/number shows if it is a WJ (Jefferson North) or a WG (Chrysler Steyer): An X (4x2) or W(4x4) stands for WJ, while a 2 (LH drive) or an 8 (RH drive) is for a WG.
So your jeep is clearly a Jefferson North build 4x4. Still donīt know how it can that you have an AC pressure transducer and not two pressure switches.

Re: AC Compressor Does't start WJ 02

I already install the AC Pressure Transducer and its running good Yeh , this switch has three contacts and finally the compressor is active.

The operation info:

The A/C pressure transducer monitors the pressures in the high side of the refrigerant system through its connection to a fitting on the A/C discharge line. The A/C pressure transducer will change its internal resistance in response to the pressures it monitors. A Schrader-type valve in the discharge line fitting permits the A/C pressure transducer to be removed or installed without disturbing the refrigerant in the A/C system.

The powertrain control module (PCM) provides a five volt reference signal and a sensor ground to the A/C pressure transducer, then monitors the output voltage of the A/C pressure transducer on a sensor return circuit to determine refrigerant pressure. The PCM is programmed to respond to this and other sensor inputs by controlling the operation of the A/C compressor clutch and the radiator cooling fan to help optimize A/C system performance and to protect the system components from damage. The PCM will disengage the A/C compressor clutch when high side pressure rises above 2971 kPa (431 psi) or falls below 206 kPa (30 psi). The A/C pressure transducer input will also disengage the A/C compressor clutch when ambient temperatures are below about 10° C (50° F) due to the pressure/temperature relationship of the refrigerant.

Thank you very much for your time without your help I would not have succeeded.
