It appears that the low pressure cutout switch isn't working

Customer Question

It appears that the low pressure cutout switch isn't working but I can't find it to replace it.
JA: How many miles are on the car? What size is your engine?
Customer: 105,000 3.0 litre. 2006 Fusion SEL
JA: What is the model of your '06 Ford?
Customer: 2006 Fusion SEL
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: The clutch was not engaging. Checked pressures by jumping relay. Pressures good. Checked resistance on the eval temp out sensor, checked out ok. If I activate the clutch with the relay out and bring the low side pressures down to normal, I can plug in the relay and the system will continue to run. In the morning when the car has sat over night, it will not activate the clutch.
JA: Anything else you think the mechanic should know?
Customer: Im just looking for the low pressure cutout switch location.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Ford Mechanic about your situation and then connect you two.

Hello, my name is***** and thanks for your question.

This system uses a pressure transducer which provides both low and high pressure signals to the PCM. It is located right at the evaporator liquid line at the firewall.
