Air Conditioning
My AC had been working and then the next morning I press the AC button and it blinks red 3 times. The low side pressure is very high around 105 when the car is running. I haven't added any r134a, is it safe to connect the can and release the pressure?
Thank you

Adding fluid will not solve the problem your system is leaking. If you put any in it will leak out.

The resolution to my issue was replacing the A/C Refrigerant Pressure Sensor (2110000283). Symptom was when you press AC button it would blink red 3 times and go off. There wasn't any leak and I wasn't low on r134a. Easy replacement from under the car. Hope this helps someone else down the road.
