To open them, you have to turn them about half a turn (180 degrees) or so clockwise BUT, you need to have your A/C hoses connected first because there are no valve cores in the OE fittings.
Turning the valves fully clockwise (frontseated) will lockout the compressor so that the oil level can be checked without losing refrigerant.

I was going to post a pic but, photo bucket is down at the moment.

not to steal this thread but you can check the com press oil? whered you get this info?

Okay, so what I'm understanding is that I have to turn the valve clockwise to add coolant, correct?

You may have the York compressor. If you do, you have the compressor that JP magazine prefers for doing the OBA setup.

does it look like this?...

Thanks for all the help guys. A/C blows colder than the wife's wj now.

For anyone else who ever has this problem, remember: CLOCKWISE to open the valve.
