First my car is an MKC not on list provided so I marked MKX. My air is blowing hot air. I bought A/C PRO and when I put tester on it went straight to the red which says see service tech.

Are you saying the A/C is overcharged with R134A?

Good morning,

Does the compressor turn on when you command A/C?

You need a set of gauges to give me the high and low side readings so I can see the readings.

Do you have a test light or voltmeter to check voltages for the system?

I attached a wiring diagram for you to view. Check the fuses for power on both sides with the key on.

I guess the compressor went out and in turn deteriorated everything else.. maybe the clutch froze up. It just seems to me that a car only 3 years old should of lasted longer. We turned it into the Ford dealer (probably while it's so expensive).

Yes, I agree. Any repair shop would do this repair for way less. The compressor, dryer and expansion valve with labor should be around $1,200.00 to $1,300.00 out the door.
