low presure AC port could be under the front wing like a ford focus on the drier canister but some renaults do not have one they only have one filler point with a large valve so you think it only has a high pressure port but in reality its the low pressure with the big valve so you swop the pipes around the AC machine ,look to see if this pipe is going to the low pressure side of the pump its a thicker pipe is the clue .
during the 1995 R12 was still in uses if you have 134a then you have the conversion here are the valve rule of thumb if the A/C pipes are thick you have the low pressure line the filter drier is a low pressure area, here the high pressure the condensor the thin line is the high pressure, go to the filter drier follow the thick line and you will find a valve that low pressure, go to the condensor the thin line you may even find a sight glass that area is the high pressure you should find a valve this is the high pressure
A/C low side ports are located on the 'thicker' plumbing vs. the 'thinner' plumbing coming off of the compressor.
Just follow the low side pipes from the compressor to the first low side port. It should also fit a quick connector onthe hose/can combination for r134a. The high pressure side port will not work with the low side hose quick connector.
