PT Cruise A?C not working

I just tried posting this but it disappeared. Sorry if it comes up twice.

So despite my resounding failure with my own car, my in-laws want me to check out the A/C on their 2006 PT Cruiser. It still blows air but only hot air. So the bought an A/C recharge kit. I looked on the all mighty Google and got some conflicting information so I want to be sure I'm doing it correctly.

One diagram I found said that this port on the top passenger side was the low pressure port. But other information says the low pressure port is on the large diameter pipe.

There's also this port which buried in the front (and I can't reach it). So which one is the low pressure port?

Only one port should the refill kit attach.

Make sure the condenser is free from damage and the ports don't leak. If the ports leak, replace the line.

The connector hose from the can to the valve should only fit one of the two. They are different sizes.

Very timely. Today, my car started blowing warm. I will be doing the same tonight.

In reply to Drewsifer:

The port in the top picture is the high side port, not low. The low side port will be on the larger tube.

See but I'm finding things like this :

But then there's this picture http://ww2.justanswer.com/uploads/tableland/2009-10-28_193612_2009-10-28_123227.png

But I can't find that port at the top of the engine compartment.

If you are using one of those recharge in a bottle kits, the fitting will only work on the low side fitting so just attach it to that one and carry on.

Well it appears I went to the correct port. So after hooking up the gauge it says the pressure is still high. So if there's pressure in the line and the air is still blowing, does that mean the compressor is most likely at fault?

The E36 M3ty fill gauge on the can? Not reliable.

A real set of AC gauges will tell way more.

You could spray the distribution block dome with something cold and see if it changes temperature on the inside temporarily.

I have a 2007 Civic that had the same symptom. It was a bad relay.
