No fault codes. No blinking lights or indication of a fault. I ran calibration test. No blinking lights or fault codes after. I ran cool down test. Also no blinking lights or fault codes. At the end of cool down test the compressor light was turned off.

Good afternoon,

Do you have a set of gauges to test the high and low side pressures? I want to see the pressures.

Also, does the compressor come on when turning the AC on?

Check the fuse listed in the diagram I attached for power on both sides.

Thank you for your reply.

I took the car to A/C service. They did not find faults or leaks.

Recovery got 150g refridgerant and 16g of oil out. ( 5,2911oz and 0, 56oz )

Vacuum took 22 minutes to 0 bar, and 4 minutes to 10 mbar ( 0,145038 psi)

27 g oil was put in ( 0, 95 oz)
5 g of dye ( 0, 8 oz )
960 g of refridgerant ( 33,863 oz)

P. HP 12.0 bar (174,045 psi )
P. LP 1, 8 bar ( 26, 1 psi )

T.S. 5.0 C ( 41 F )
T.U 22.0 C (71, 6 F )

I fear the same could happen again. And would like to know how could I spot the fault as it happens. Or if there is nothing I can do to help diagnose possible recurring fault.

Thank you :)

OK, since you added the dye, keep an eye out for any leaks by using a good bright LED flashlight. It will glow green or yellow depending on the dye you are using.
