2002 A/C low pressure switch location

[bcribb52]

I have a 2002 Thunderbird and the ac compressor clutch don’t come on. Pressure seems to be fine on Freon. I can jump the pins with the relay out and the clutch will engage. I’m thinking a bad low pressure switch but not sure where it is and can I replace the switch without losing my Freon. Thanks.

It is called an A/C pressure transducer sensor.
I assumed the wiring diagram should be the same for a 2002-2005.


The switch or sensor is in the engine bay on the driver side on my 04 in the high side hose coming out of the condenser.
About 4 inches from where my finger is.

I-replaced the switch. The compressor still won’t come on. I’m confused with this one

It's a very complex system and it could be anything my suggestion, take it to a qualified repair shop if you have one in your area that specializes in a/c repair even better and let them give you a diagnostic, beginning by accessing any trouble code codes related to the a/c system.

This code showed up on my scan tool.
Evaporator Sensor Discharge Circuit, Short to ground.
Gonna research the code and find out where the sensor is.

The sensor seems to be in the evaporator case behind the dashboard.
