The sight glass provides accurate diagnosis only under the following conditions.
If the vehicle can be tested under these conditions, check the sight glass appearance and compare to the chart.
* Engine speed Idling
* A/C switch "ON"
* Blower fan operating at highest speed
* Air source selector lever at "RECIRC"
* Temperature control knob at coldest position
* Ambient temperature below 35 °C (95 °F) and humidity below 70% (See NOTE 1)
* High side pressure less than 1470 kPa (15 kg/cm
2 / 213 psi) (See NOTE 2)

NOTE 1
If the vehicle cannot be moved to a testing location that meets these specifications, then the sight glass cannot be
used for diagnosis. You must discharge and recover the refrigerant, then recharge the system with the specified
amount of refrigerant. Then continue checking the system performance.

NOTE 2
If the high side pressure is greater than stated, the sight glass cannot be used for diagnosis. You must discharge
and recover the refrigerant, then recharge the system with the specified amount of refrigerant. Then continue
checking system performance.
