any help on how to add r134a?

The fill is on the line on the drivers side front wheel, remove the plastic shield, it has a plastic cap. I hope for your sake this is not an indication of evaporator leakage which is very common for these cars. To replace will cost almost the value of the car, and requires the removal of the entire dash

thanks, i did find the LP conn but looking at it seems to have a ball on the inside vs a pin like in my other japanese cars.
a small leak, has deteriorated over the last 2 yrs so just needs a little charge, vent temp is around 55F not 45 as should be, so hopefully not a major job......
