Turn the A/C on complete, and set the fan speed to "high."3Check for cold air being blown in to the cabin. When the A/C does not blow cold, this could indicate a faulty compressor or possibly a lack of refrigerant in the cooling lines.4Remove the blue cap on the low-pressure line. The low-pressure line could be the only one particular having a blue cap operating out from the A/C compressor towards the firewall.

5Place the pressure gauge quick-connect fitting more than the top with the valve on the low-pressure line.6Open the verify valve on the pressure gauge, and verify to produce sure the pressure in the A/C lines is below the red mark on the pressure gauge. For those who have pressure that falls inside the green band on the pressure gauge, then the A/C program is pressurized---meaning there is refrigerant in the lines. Should you be not blowing cold air inside the cabin, it indicates that the compressor has failed. If there is no pressure or low pressure in the lines, there is a leak somewhere inside the lines.7Many times when the compressor fails, there's also a leak in the compressor.
