Today I was poking around my A/C system with the intention of putting a charge into it (my Dad has an R12 liscense for just such an emergency). After removing the cover in the front of the car (and the spare and water jug) I found a screw cap on the high pressure line of the system. I could not find a low pressure cap anywhere. Upon a quick review of the svc manual it appears the charge point is on the compressor (on the engine). Is this correct? Sight glass is in a great place - I have a feeling I am missing something. I did not have the time to pull the wheel and cover to have a close look at the compressor. Another question. When I did remove that high pressure cap freon leaked out of the connector/valve freely. I am assuming this is not to spec . Anybody have a part number for this little valve? I will get one from FOHou or online somewhere. I was happy to see I had some pressure. I am betting a quick charge will result in a working A/C...fingers crossed.
